How Does a Screw Work?
The world of screws is vast, and you’ll find no shortage of different options when you shop for screws for your next project. How does a screw work?
A screw has the same overall shape as a nail, but it includes a spiraling groove travelling around and down the shaft. The head has several options, including hex, pan, flat and round. Drives can be slotted or made with a Phillips head design for driving.
When you need to hold two materials or objects together, the groove helps keep the screw in place and the bond secure. To drive the screw into a material, you’ll need a screwdriver or drill that’s compatible with the head design.
There are many different types of screws, and while their exact uses differ, what a screw does best is hold two things together. What are different types of screws used for? Here’s a primer on the different types of screws available to you, as well as some key information as you evaluate what types of screws will work best to meet your needs.
What Is a Screw Used For?
Screws are fasteners for all sorts of construction projects, large and small. The reason there are so many different types of screws is that there are so many different ways objects and materials need to be fastened.
Sometimes screws are classified by the material they are used to fasten. For example, you might find you need concrete screws for fastening objects to concrete, wood screws for fastening objects to wood, or drywall screws for fastening objects to drywall. No one screw or fastening could possibly serve as a one-size-fits-all solution, because there are simply too many different needs and applications for screws and fasteners.
What Are the Different Types of Screws?
Because of how many different ways there are to use screws, you’ll find there are tons of different types of screws. Here are just a few of the different kinds you’ll find when searching for the right solution:
These are just a few of the different types of screws. You may find that the screw you need is classified into one of the categories above, but it’s also categorized by its drive type (Phillips, slotted, combination, star, etc.) or by the shape of its head (oval, flat, button, round, pan, etc.). In some cases, you may find a screw is classified by a combination of terms. For example, you might find that you need a slotted flathead metal screw.
What Is the Difference Between a Self-Tapping Screw and a Normal Screw?
With most screws, you’ll need to drill a pilot hole that creates threads and helps guide the screw into a secure spot. That’s not the case with self-tapping (or self-drilling) screws. When you choose self-tapping screws, there’s no need for a pilot hole. The screw creates its own threads as it is installed and remains tightly in place despite any activity or vibrations.
What’s the benefit of self-tapping screws?
Self-tapping screws save tons of time when you’re working on a significant project. For example, if you’re working to fasten objects and you need to use several dozen screws to get the job done, choosing self-tapping screws can significantly decrease the amount of time the project takes you. This is incredibly important in large construction projects where getting the project done on time is of the utmost importance.
These screws are also reliable, as they hold materials together firmly and have a long service life. Installing self-tapping screws with a coating can also prevent discoloration of the material due to rust or corrosion, making these fasteners ideal for harsh environments.

How to Use Self-Tapping Wood Screws
All hardware stores which are truly really worth the name have an extensive assortment of wood screws and tools, bolts and nails for utilizing these items. Adding more difficulty, each type of tool and securer may possess a somewhat different method of correct usage.
Let us take a glimpse into how you will make use of wood fasteners as well as what you do not do with wood screws. At All Points Fasteners, we have a variety of self-tapping wood screws for do-it-yourself projects.
What Does a Wood Screw Look Like?
A wood screw has shorter threading that is not throughout the whole body and fewer pitches, made for projects involving lumber, plywood and wood materials. Compared to other screws, they are easier to drive into wood, which is why you should always use a wood screw for wood projects.
You need to make certain the materials the wood screws are produced from will be the best sort of fasteners for your project. Some metals tend to be a lot more corrosion-proof, plus most can leave a terrible spot if you use them in wood because they react to the sap still left in the wood. Before purchasing self-drilling wood screws, do some study and ascertain exactly which type of screws you will be using.
Are Wood Screws Self Tapping?
Wood screws are self-tapping because they can tap their threads into the wood material. Before you can use a wood screw, you must drill a pilot hole, because self-tapping screws are not self-drilling. This pilot hole must be smaller than the screw, so the threads can go into the wood material and create a secure fastening.
How to Use Self-Tapping Wood Screws
The first thing you need to do when using wood fasteners is to get hold of individual tapping anchoring fasteners and regular wood screws. The self exploit fastener generally is a lot easier to install because it requires much less to do the job.
All you need to do is make use of either a Philips or flat head screwdriver. Set the point of the fastener on the spot you wish it to be and begin screwing. As you turn the screwdriver, the fastener should cut into the wood and make a hole for itself completely — no drills required.
Afterward, there is the standard self-tapping wood fastener. You will require a drill for doing so. You will have to mark out all of the places where you need to place fasteners and drill a hole in the wood, which is the correct size for the fasteners you will be using. Then, you need to go along and, while employing the proper kind of screwdriver, screw all the screws into place.
What Are the Risks of Self-Drilling Wood Screws?
The hazards of using self-tapping wood screws are:
- Not getting all of them in straight: An individual tapping screw might go in the wood skew because of the grain of your wood or from unequal pressure on the screwdriver as it’s flipped into the wood. If you help a drill afterward, you run a slightly decreased chance of going askew, as you are not going to place a lot of pressure on your drill to bite into the wood, and the drill isn’t possible to get pushed close because of the wood grain.
- Making the pilot hole too big: As a substitute, you risk utilizing a drill bit that’s a touch too large for the anchoring screws you will be utilizing in your do-it-yourself project. Using an oversized drill bit means that the fastener is not going to hold well, so the fastening won’t be secure.

This and That About Wood Screws
When executing Do-it-Yourself projects, quite a few folks get perplexed about what fasteners to use to perform their job. There are a lot of choices…so many dimensions to decide upon. What length should the screw be? How thick of a shank do I need? Philips drives? Torx drive? Hex Head? What type of point do you need? Zip? Tek Point? Type 17 point? There is a reason why each fastener has a certain specification or attribute and if you don’t know how your screw is going to perform you will end up blaming the screw if it doesn’t perform how you want it to when the real cause was how it was used. Let’s take a look at how you can figure out what sort of wood screws to use.
As the name suggests, wood screws are used when you are doing work with wood. Many of your wood screws will be produced from a metal that isn’t likely to react with the resins as well as treatment chemicals within the wood. Some metals will leave a rather unpleasant looking stain if they come into contact with particular chemicals or resins. It used to be that you only had two choices of material for wood screws – plain carbon steel or carbon steel with zinc plating. Sometimes you could locate stainless wood screws. Now however, you can find screws for wood, usually deck screws, with special plating to protect them from chemically treated wood. They are generally available in 500 and 1000 hour salt spray tested.
There are a few selections when it comes to wood screws or rather, screws you use in wood. There are wood screws that require pre-drilling since their point isn’t sharp or hard enough to self start. They have coarse threads so that the wood will fill in between the threads and help to prevent them from pulling out of the softer wood or particle board. Generally, they have a prominent smooth shank (sometimes called a shoulder) to help pull together the two pieces being fastened.
Another option is what is referred to as a Type 17 point, which has a very sharp point and the thread will go all the way to the tip of the point with finer threads, generally 18 threads per inch. These work wonderful in the harder woods. As you put pressure on the screw and turn it using a drill it’ll cut into the wood and create its very own hole. These are typically rather tight fitting and don’t often tear loose. They have a cut at the tip of the point so that the displaced wood has an avenue of escape and keeps the wood from splitting.
The vast majority of wood screws may also have an area of non-threaded metal just beneath the head. This is so that you are able to allow the top of the screw to slide through the top piece of wood so you are able to tightly fasten the two bits of wood together.
For DIY projects to go easily, make certain that you pick the proper screw with the right features for the wood you’re going to be using and for the correct application. You should also determine if you need to use of the self tapping variety or if you will need to have to pre-drill. Just about all wood screws will work for just about all woods, however getting the best fastener for the job is definitely ideal.
Here’s a quick suggestion to point you in the right direction: For harder woods, fine threaded wood screws work best. For the softer woods or particle board, the coarse threaded screws are more appropriate. These are also often called particle board screws.
Self-Tapping Deck Screws
Deck Screws – Wood Screws? No splits, pre-drill or mushrooming Fine hardwoods, composite, & pine.
Self-tapping wood screws , and other screws, really make a big difference in the outcomes of any house project. These basic products can be the difference between a finished project that can last for a lot of years and one which may fall apart the first time you use it. Everyone has made compromises when performing project work. This is typically due to the inconvenience of having to run to the store for the little and seemingly insignificant part that simply does not appear to be worth the effort to make the trip. If you consider arrogance in your venture, you may want to rethink if that is true. If it seriously did not make a difference you may not have the multitude of options from that to choose. Wood screws come in dozens of lengths and have certain characteristics for particular uses.
One leading example of a specialty wood screw is for outside decking. Deck screws are specially coated to be rust resistant. Doing so can help decrease the chance of unpleasant rust marks from developing on your outdoor patio stretch. The rust resistant covering additionally keeps the screw from becoming deteriorated by weather conditions conditions. Because they are exposed to the outdoors, and in the case of the outdoor patio, are especially vulnerable to the elements. This is simply because the fasteners are employed on a flat surface that can pool water in the fastener holes. A failure can result should the fastener rust through. The resulting loose decking could additionally cause a safety hazard and homeowner liability. The enzymes and chemical substances employed in treated timber can be hard on the screw as well. The small expense in employing the right screws pales in comparability to the doable consequences. Recall, the covering is merely corrosion proof so to treat the outdoor patio face as needed to hold each the wood and fasteners in good shape.
Wood screws have come a long way in their overall performance and the know-how these folks employ. This technological innovation allows for greater, and lengthier long lasting benefits with your home projects. This translates into much better wanting tasks using an expert quality. One recent development in of a wood screw is the use of different drive heads. The most popular are still the Phillips head screws. The cross shaped drive head provides safe contact in between the driver and the screw. They also permit for a standard of connection offering the user the ability to do the job on different planes while taking care of control of the fastener. The sq disk will take doing so connection separating app and screw and creates a contact point which not only supply much better grip during the drive, but attaches so snugly that you can do the job upside straight down or sideways without losing contact using the drive head. The regular fastener head has its uses, but for comfort the sq drive and Phillips head offer added control.
The design of a wood screw is being founded on the particular characteristics of how wood works using the fastener. If you evaluate a metal screw to a wood screw you will see most differences. The wood screw is tapered producing the connection more safe. A metal screw does not possess this taper, and because of doing so, must not be employed in wood applications. The screw can have a propensity to again from the hole leading to the joint to fail. Wood screws usually do not possess threads that extend all the way to the screw head. This feature helps keep the fastener firmly in place. The best advice is if you do have a wood venture, use self-tapping wood screws for an ideal result.
Self-Tapping Sheet Metal Screw, Wood Screw or Lag Screw?
Even pros are confused at times on which fastener they are using on a job. They often wonder, what’s the difference between a wood screw vs. a metal screw and which do I need. When you are putting screws in to wood, then they have to be wood screws right? Well, possibly…….One good clue to spot the difference between a wood screw vs. sheet metal screw is to check underneath the head of the screws.
If the screw is fully threaded with a sharp point, you most likely have a sheet metal screw.
If the screw only is about 2/3 threaded with a smooth shank underneath the head, you are looking at a wood screw. Typically in the past, wood screws were not case-hardened like sheet metal screws and, unlike sheet metal screws, were plain steel and not plated.
But these days, there are many more options available. Some companies carry case-hardened wood screws and many are now zinc plated which gives them more protection from corrosion. The purpose of the smooth shank underneath the head was so that the two pieces of wood being fastened would draw together once the threads past through the first piece of wood.
Then there is the lag screw which is also used in wood. Frequently a customer will ask for a lag screw when, in fact, he is wanting a #14×3 self-tapping Hex Washer Head Sheet Metal Type A screw. A quick way to figure out which one you want is to ask:
1. Does it have a smooth shank underneath the head? and …
2. Does it have an attached washer on the hex head.
As you can tell from the pictures above, lag screws and sheet metal screws look quite different.
Zip Screws and Tek Screws
Self tapping screws, such as zip screws and tek screws, are perfect for jobs when you plan to connect materials that are of different varieties, such as wood to metal, metal to plastics and metal to metal. Self tapping screws are really versatile and simple to use since they will tap their own threads as you drive them into your materials, and this in turn will save you time and time equals money! There are many kinds of self tapping screws you can buy today and they each have their own purpose.
There are fundamentally two sorts of popular self tapping fasteners available, zip screws and tek screws. Type A screws are also self-tapping, as they tap their own threads, even so, they are not as popular as they normally need a pilot hole to get them started.
There are two kinds of tips for self-tapping screws and that they are the self piercing screw, also identified as zip screws, and the other is the drill bit tip, tek screw type.
Tek screws are intended for use in soft steel or other metals. The points are numbered from 1 through 5, The larger the number, the thicker metal it can go through without a pilot hole. For example, a # 5 tek point can drill a 0.5 in (12.7 mm) of steel. Contractors at times question the quality of their tek screws when the screws break, when the actual reason for breakage is the application for which they are being used. The following is a very simplified reason for heads of tek screws sometimes popping or screws twisting and breaking when drilled into steel too thick for the tek screw used. With a standard tek screw, the front of the fastener will be drilling in slower while the drill bit is drilling the pilot hole than when the threads of the tek screw catch the material being drilled. Once the threads catch, the screw will turn as fast as the TPI. In other words, if the screw is 16tpi, the screw will go in a 16th of an inch each time it turns. The problem becomes, if it is a thick piece of metal, the threads will catch before the drill bit is done drilling through the metal. The consequence is that the front of the fastener will be moving slower than the back of the screw and the screw will break. However, by having the drill bit of the screw longer up the shank of the screw and changing the threads per inch to a finer thread (24 threads per inch), the front and the back of the screw will move at the same time and the tek screws won’t break.
While self-piercing zip screws can pierce their own hole in to soft metals and create its own threads, this is usually done with thinner gauges of metal starting at 24 gauge. Needlepoint screws, are also commonly known as zip screws and are self-tapping in that they tap their own threads.
They are also sometimes referred to as self-piercing screws because they will ‘self start’ with soft metals when pressure is applied. #8 x1/2 Hex Washer Head Needlepoint screws (zip screws) have reportedly worked best when used in square duct with 30 and 28 gauge metals. Contractors state that they have better luck with a #7 needlepoint when doing round pipe with 24 and 26 gauge metals. Application is very important when choosing which fastener to use in your specific job, otherwise, the screws may not perform in the way that they were expected. Many screw ‘failures’ are actually misapplications. Although some say that they have been able to use #7 zip screws in up to 20 gauge metals, it has been our experience that when working with metal 22 gauges and thicker, drill bit tip (tek screw type) really does the job much easier.
Zip screws and tek screws are readily available to help save you time and money.
