Have you ever wondered how those handy little screws work? The ones that don't require a pilot hole and can be used on a variety of materials? Well, self tapping screws are pretty amazing and have a variety of applications. Let's take a closer look at how they work.

How Self Tapping Screws Work

Self tapping screws are specially designed to make their own threads as they are driven into the material. This is accomplished by a series of precision cutting edges on the tip of the screw. As the screw is turned, these cutting edges score the surface of the material and displace enough material so that threads can be formed.

While this may sound like it would cause damage to the surrounding area, the screws are designed so that the cutting edges only score the surface during initial installation. After the first few turns, the cutting edges retract into the body of the screw so that it can be tightly fastened without damaging the material. This also allows for easy removal if necessary.

The Benefits of Using Self Tapping Screws

So now that we know how these special screws work, let's look at some of the benefits of using them. First of all, because self tapping screws don't require a pilot hole, they can be used on materials that are too thin to drill a hole in without causing damage. This makes them perfect for working with delicate materials such as plywood or plastic. They are also great for quickly attaching two pieces of material together without having to thread a nut onto a bolt.

Another benefit is that they can create their own threads in any type of material, even metals. This means that you can use them on projects where you need to attach two pieces of dissimilar materials together. For example, you could use them to attach a piece of wood trim to metal siding on your house without having to drill separate pilot holes for each type of material.

Self tapping screws are an essential tool for anyone who works with wood, metal, or plastic. They are easy to use and provide a strong connection between two pieces of material. Whether you're working on a quick repair job or a more involved construction project, these screws should be your go-to choice when joining two pieces together.
