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.

Sheet Metal Versus Wood Screws

While it’s certainly possible to use just any fastener for a project, your work will only last if the product suits the material and the environment. Each situation is unique, and it’s helpful to know when to use a wood screw versus a sheet metal screw. The differences between the two include:

  • Sheet metal: These fasteners are fully threaded all along the shank and have a sharper tip at the end. You can attach thin sheets of metal with this option.
  • Wood: The threading takes up two-thirds of the shank, while the rest is smooth up to the head. This design grips two pieces of wood together.

If you need fasteners of a specific length or diameter, All Points Fasteners can help you find the right option. We are one of the only online fastener companies with a live chat on our website, so support from us is available at any time. Our representatives will do their best to help you choose the right product based on the information you provide.

Applications for Sheet Metal Screws and Wood Screws

Particular jobs need certain screws for them to be successful. You can apply these two types of fasteners in many situations, such as:

  • Heating and air: You can use sheet metal screws to attach thin metals in jobs such as HVAC installations.
  • Constructing outdoor decks: Wood screws have a special coating to prevent corrosion that could result in stains on your lumber. Sheds or other projects that will be exposed to the elements are also opportunities to use wood screws.
  • Residential and commercial: Both fasteners have their uses in building homes or larger structures.

If you want to know which screws to use in specific situations, such as when you need to screw metal to wood, All Points Fasteners can guide you in the right direction.

Zip Screws and Tek Screws

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.
