Nail Size Chart

Different construction projects require fasteners with various qualities to ensure the project’s structural soundness. Construction workers use nails in all kinds of tasks, from roofing to flooring. It’s essential for workers to use a suitable nail size, type and material for their application.

Nail size is standardized according to several factors, including diameter, gauge and shank length. These characteristics make various nails suitable for different projects. Understanding nail size is essential for selecting the proper hardware for your job and potentially saving yourself money and time. Discover the right nail for your application with these nail size charts.

Standards for nail sizes

Standards for Nail Sizes

The nail sizing charts below provide the industry standards for nail sizing. To understand a nail size chart, you first need to know the measurements used to determine nail size:

  • Penny size: The penny size is a standard unit of measurement for nails, abbreviated as “d.” This measurement initially referred to the price of 100 nails, with longer nails costing more. Now penny size indicates nail size, although it doesn’t correspond precisely to another unit of measurement. For example, a 16 penny nail is abbreviated as a 16d nail and is longer than an 8d nail.
  • Gauge: A nail’s gauge is a unit of measurement referring to its diameter or thickness. Higher nail gauge sizes correspond to thinner nails, with smaller nail gauge sizes correlating to thicker, stronger nails. For instance, a 12-gauge nail is thinner than a 5-gauge nail.
  • Shank diameter: The shank of the nail refers to its longer portion driven into the material rather than the flat head. The shank’s diameter is a measurement of its thickness in inches.
  • Shank length: Shank length refers to nail length and is measured in inches.
  • Head diameter: The nail head diameter is an approximate measurement of the nail’s head in inches.

Nail Types

Nails exist in various sizes and types to serve different functions. Pullout resistance is one factor that influences nail selection. Nails with threaded or ringed shanks resist pullout more than those with smooth shanks. Whether a project involves hardwood or softwood also influences a construction team’s choice of nail.

Nail materials vary, with stainless steel and copper-plated nails some of the most common. Copper nails provide excellent structural support and longevity, making them ideal for environments with high humidity. Stainless steel nails work well with soft materials and provide corrosion and climate resistance.

Different applications also require unique nail heads. For roofing, nails must lie discreetly under shingles while providing tear resistance. Flat, wide nail heads are ideal for this situation. Specialty nail designs and coatings allow construction workers to find suitable hardware for their job.

Based on these factors, the three most used nail types include:

  • Common nails: Common nails have smooth shanks ideal for structural work, repairs and other applications requiring typical resistance. The smooth shank of common nails makes them adequate for supporting lateral loads where pullout resistance is a minor factor.
  • Box nails: Box nails have smooth shanks similar to common nails. The primary difference is that box nails typically have a slightly higher gauge. These nails are ideal for projects where the construction team is less concerned with holding strength, like working with thinner wood, crates, trims and other non-structural projects.
  • Annular and threaded nails: Annular or threaded nails have threaded shanks that provide additional grip once inserted into the material. These nails offer superior pullout resistance and structural support. Construction workers use annular nails in projects that require extra holding power, like subflooring and drywall replacement.

How Supply Chain Issues Are Impacting the Fastener Industry

How Supply Chain Issues Are Impacting the Fastener Industry

From the pandemic to sky-high inflation, the past few years have been challenging for many industries. Factory shutdowns and port disruptions slowed the production of many products that the world needs to continue functioning. Recently, the fastener supply chain hasn’t been immune from problems, including shortages.

Supply chain troubles can cause your company to fall behind on its projects or even lose customers. Fortunately, there are ways to manage the shortages and adjust to keep your projects on time and on schedule as much as possible.

What’s Driving Fastener Supply Chain Issues?

Supply chain problems are complex, and there are several factors that contribute to the overall issue and lead to material shortages. Some of the concerns behind fastener supply chain issues are:

  • Labor shortages: Companies need employees to work in the plants that manufacture fasteners like screws and bolts. They also need workers to load the containers and work at the ports. Labor shortages, due to illness, isolation requirements or people leaving their jobs, have affected the speed at which companies can produce and ship fasteners.
  • Container shortages: Fasteners that come to the U.S. from abroad usually make the journey on container ships. A shortage of available containers has made it challenging for supplies to be shipped. The container shortage is partly caused by a labor shortage, as there aren’t enough drivers or vehicles to return the containers to their origin.
  • Port congestion: In addition to a limited number of containers, many of the ports that receive container ships have also experienced congestion, with ships having to wait to be unloaded. The delay in unloading ships has led to a delay in products getting to the companies that need them.
  • Limited materials: There’s been a shortage of raw materials needed to produce specific fasteners, such as stainless steel. In some cases, material shortages are directly connected to labor shortages.

How to Cope With Industrial Fastener Supply Chain Issues

If your company can’t get the fasteners it needs, it may have to delay projects or use sub-standard supplies as a stopgap. Sometimes, an alternative fastener isn’t an option, as it can void warranties.

The best way to deal with fastener supply chain concerns is to work with a fastener importer and distributor, particularly one that specializes in finding hard-to-locate screws and other fasteners. All Points Fasteners is working hard to find a solution to the insulation screw shortage for its clients and will work hard to find and source other hard-to-locate fasteners you need.

Why You Shouldn’t Over-Torque Fasteners

Installing screws to fasten materials is a standard procedure for construction contractors, HVAC technicians, roofers and other professionals working in the trades. While the tendency is to make the fasteners as tight as possible to ensure a secure fit, it doesn’t always produce the best results. Over-tightening screws can even do more harm than good in some situations.

What Happens When You Over-Torque Screws?

Making screws too tight can have numerous detrimental consequences.

Damage to the Screw Thread

The thread on a screw performs the essential function of converting torque into linear force during the fastening process. Over-tightening the fastener can damage the thread, preventing it from maintaining a secure fit.

Inability to Remove the Screw

It’s possible to install a screw so tightly that you won’t be able to take it back out again without significant effort. You may need several items, including a hammer, impact driver, rotary tool and a lubricant such as Liquid Wrench to remove the screw.

Ruining the Fastener

You can damage screws by making them too tight. Embedding the fastener too deeply into the material increases the torque required for subsequent tightening or loosening. If the screw is so tight that the tools mentioned above cannot move it, applying them may cause the screw head to strip out or snap off, which compromises the integrity of the attachment and renders the fastener useless.

Damage to the Workpiece

damage the work piece

If you’re not careful when tightening screws, you could potentially harm materials such as sheet metal or wood. This could lead to costly project delays, and replacing the materials creates additional expenses and cost overruns.


Although it might sound counterintuitive, over-torquing a screw won’t prevent it from loosening over time. Vibrations, wear and tear and other external factors will eventually take their toll and cause the screw to lose its grip on the material. You’ll need to install a locking nut, locking washer, threadlocker solution or a combination of these items to keep the screw secure.

Top Mistakes to Avoid With Fasteners

Top Mistakes to Avoid With Fasteners

Fasteners are vital for all types of projects, but when you don’t use them in the application they were designed to be used, you can affect your project in the long term. Understanding the top fastener mistakes can help you use screws, bolts, nails and other types more effectively.

Choosing the Wrong Material

When selecting fasteners, it’s essential to consider the material you’re using and the environment the fastener has to operate in.

For example, grade 316 stainless steel is corrosion-resistant in extreme saltwater environments, which is useful in some applications, but not others. You’ll also want to consider how your fastener will interact with the material you’re working with. Aluminum and stainless steel cause galvanic corrosion that weakens the material and makes it more susceptible to rust.

Forgetting About Dimensional Accuracy

Your fasteners need to be the right size to work with your project. The size of your fastener will determine how well it connects your materials and how stable that connection is. For example, a fastener off by a single millimeter can create uneven load distribution with a washer, leading to loosening over time. As these parts loosen, they corrode faster and decrease the life span of your project.

Creating plans before building your project is valuable for dimensional accuracy. With these plans, you can see how thick your materials are and determine which length is best for every fastening application.

Using the Wrong Tool

If you use the wrong tool with your fastener, you may negatively affect the structural integrity of your project. For example, using the wrong screw gun bit may make it difficult to tighten the fastener as much as it needs. Rotating between a screw gun and an impact driver could cause an unevenly distributed load. Even if you choose the right screw size and material, the wrong tool can stand in your way. Using impact tools to drive in screws is by far the most common inappropriate tool use which can, over time, cause the heads to pop or compromise the structure of the screw.


While tightening your fasteners is essential for stability, overdriving can also cause issues. When using a washer, overdriving causes excess pressure that reduces sealing performance over time. These sealing capabilities are necessary for many applications, and without them, your project may sustain water damage or corrode faster.

Coarse Thread Vs. Fine Thread Fasteners

Coarse Thread vs. Fine Thread Fasteners

When you’re planning your next project, choosing the best fastener type is essential to the overall function of your final product. Coarse and fine thread screws are two specific fastener types that work well in various applications. The difference between fine and coarse thread screws can help you determine which one is right for your next project.

What Is a Coarse Thread Screw?

Coarse thread fasteners have a wider thread pitch — the distance between each row of threading. Since this pitch is wider, coarse thread screws have a low number of threads across the distance of the fastener.

Coarse threads allow more material to settle between the threading, making it harder for these screws to strip or cross thread. The threading can take on damage like nicks and marring and still function efficiently. Coarse threads are also less likely to gall or seize during tightening, making them easier to install.

What Are Fine Thread Screws?

In contrast, because of a narrow thread pitch, fine thread screws have a larger number of threads per distance. These threads offer higher tensile strength than coarse thread fasteners, and they’re often easier to tap. Since fine threading involves narrow, shallow ridges, there’s material to cut when forming threads.

Fine thread screws also have a shallow pitch or helical angle, making them more resistant to vibration. These fasteners also have less heft than their coarse counterparts, so they require less torque to install.

Which One Is Right for Your Application?

Choosing the right fastener for your application is about understanding the environment, the material and how the screw will need to perform.

Generally, coarse thread screws work well in most applications. These fasteners offer the strength and ease needed for many construction and industrial applications. Coarse threads work well with the following materials:

  • Softwoods
  • Plywood
  • Oriented strand board (OSB)
  • Wood studs

Fine threads are best for applications where vibration may be an issue. You’ll often find fine thread fasteners in machine parts, transmission parts and hydraulic systems because these applications involve high vibration. The materials best suited to fine thread screws include:

  • Hardwood
  • High gauge metals, including aluminum, titanium and stainless steel
  • Metal studs

What Is a Square Drive Screw?

What Is a Square Drive Screw?

The square drive screw is designed to be used in installing decking, furniture manufacturing operations, along with other demanding industries that use tough materials like hardwoods. Screws can utilize several  other drive types, including:

  • Allen drives: Screws with Allen drives have socket heads with multiple sides. They risk camming out under excessive force.
  • Hex heads: Screws with hex heads are used with a wrench or a socket and ratchet.
  • Slotted and Phillips drives: These drives are some of the most common. However, screw heads with slotted and Phillips drives usually cam out easily.

Until the square drive screw was invented, nearly all screws were slot head or straight drive screws. Square drives, also known as Robertson drives, lower the risk of camming out. For one-handed driving and an excellent grip, look no further than the square drive.

How Square Drive Screws Work

Square drive screws are most resistant to stripping out or screwdriver slips.

Square drive screws make it easier for screw tips to remain in place during driving. They also help prevent slipping and stripping. Square drive wood screws have a thick shaft and are made of softer metal, allowing them to drive through wood and reduce cam out. This design means you can avoid scarring up the finish and make joints tight on the first attempt.

The square drive screw has a central square head that fits neatly into a driver, which comes in handy when you’re working on a project that uses join angles and composite materials. You can also disassemble your project without damaging the item or stripping the screw. The heat-treated steel offers dependable strength, and for better holding, the optimized thread depth reduces crumbling between threads.

The sharp thread angle also cuts cleanly into wood to minimize splitting or cracking. Square drive screws reduce driving resistance due to their minimum body diameter, and the sharp point can get a screw started quickly without a pilot hole.

How Strong Are Deck Screws?

How Strong Are Deck Screws?

Screws can be found in a variety of sizes and shapes, and though many people assume screw types are interchangeable, there are important differences between wood screws and deck screws. Though deck screws and wood screws look similar, they have different purposes.

Compared to thin nails, deck screws are much stronger and can hold considerably more weight. Deck screws are also stronger than wood screws and tend to be made from stainless steel or copper for increased durability.

What Are Deck Screws Used For?

Deck screws are used for outside jobs like building decks and fencing. When buying these fasteners, keep in mind that there are different types of deck screws to choose from.


  • Wood deck screws: This type of screw has an unthreaded shank and a coarse-threaded portion.
  • Composite deck screws: This type of screw has finer threads and a smaller head. Some also feature an extra thread set that prevents the mounding of the composite materials at the screw’s head.


Deck screws are perfect for outdoor use because they’re composed of stainless steel, galvanized steel or copper to prevent rust and increase corrosion resistance, which is particularly important in a wet environment. These screws have flattened, countersunk, flare or bugle-shaped heads. The heads of deck screws can prevent them from sinking into the material and splitting or cracking it.

Deck screws also have unique threaded shanks that increase their durability. The aggressive point and sharp threads increase the screw’s hold once it’s in place. This sharp, deep threading on deck screws allows them to easily cut into a workpiece, and they are also better able to withstand humidity, rain and salty water than wood screws.

If you want to construct a robust, sturdy deck, you’ll need deck screws for attaching decking and railings to the framing.

Guide to Buying Tek Screws

If you need self-drilling, tek type, screws for your project, it’s important to know what type you need. There are several things to keep in mind when making a decision.

What You Should Know When Buying Tek Screws

There are many features to consider when buying tek screws. Before you buy, determine:

  • Head style: This aspect will determine how the screw distributes stress and what the finished surface will look like. For instance, hex heads are standard for heavy-duty applications like roofing and HVAC and lighter uses like fastening components to liner panels.
  • Shank size: Shank describes the thickness of the screw. A higher number shank means a thicker screw.  Think dress size.  A #12 is thicker than a #10 shank. You should use higher thicknesses for heavy-duty applications.
  • Length: On Hex heads, pan heads, modified truss heads and pancake head screws, screw length measures from right below the head to the screw tip. Choose this measurement based on how thick your materials are and how much grip you need. On countersinking screws, you would measure the entire screw since the full length of the screw will be embedded in the material.
  • Point type: Self-drilling screws, also known as tek screws, have four popular sizes – #2, #3, #4 and #5.  The higher the number, the thicker the metal the tek screw can penetrate. A #5 drill bit tip can drill through up to ½ inch steel.
  • Plating: Your screw’s outer coating affects its response to the surrounding environment. Zinc plating is standard but can also be found with ceramic coating.
  • Material:    The least expensive self-drilling tek type screws are manufactured in carbon steel.  They are also available in 410 stainless (magnetic) and 18-8 stainless (non-magnetic).  18-8 stainless and 300 series stainless are best used in aluminum.  410 stainless tek screws can be used in heavier gauges but can give you surface rust without compromising the integrity of the screw.  We even have bi-metal tek screws, where the drill bit tip is carbon steel but the body of the screw is non-magnetic stainless.  These screws are pricey but they do the job of drilling through steel but giving you the best in rust resistance.
  • Time: How many screws do you need, and when do you need them? Call us early enough, and we can ship the same day any items we have on the floor.  We offer painted screws for a cleaner look, however, custom paint colors will need time to prepare so don’t wait until the last minute to order!

Buy Tek Screws Based on Application

There are many types of tek screws for specific applications. Some specialized screw types include:

  • Heating and ventilation:  For commercial hvac our 10×3/4 hex washer head is the most popular.
  • Metal framing: You can use these screws to connect steel pieces.
  • Stitching screws: These screws work best for stitching cladding panels.
  • Reamer Tek screws: Choose these screws when you need to attach composites or timber to steel.
  • Beam Busters: When you’re working with thicker metal, these screws work where standard tek screws don’t.
  • Composite panel fasteners: These screws work for roofing applications, cladding, cold and hot rolled rails, and purlins. They also work well for fastening components and liner panels to heavy steel.
