What Are Self-Tapping Screws?

 

Self-tapping screws, also known as tapping screws, are designed to cut their own threads in which they are screwed.

Self-tapping screws have a wide range of applications. These tap tite screws are suitable for a variety of materials, including plastic, metal, and even wood. When inserted into a hole in the material, they can create their own threads, eliminating the need for pre-drilling. Self-tapping screws can be used in both DIY and industrial applications.

There are two types of self-tapping screws-

Thread forming:

These screws do not have a pointed tip, so you will need to drill a pilot hole before using them. Thread-forming screws are commonly used to join plastic materials. They typically grip material more tightly due to their design

Thread-Tapping:

Although these screws do not require a pilot hole, one can be drilled to facilitate fastening. Thread-tapping screws remove material while also creating a path for the screw.

There are many different types of self-tapping screws, and the one you choose will depend on the project at hand. Let’s take a look at some of the most popular types.

Countersunk or flat head self-drilling screws: These allow for a flush finish because the screw head sits below the surface of the surrounding material. This results in a flat and smooth finish.

The screw head is less likely to be compromised and distorted when driving into the material due to the shape of the driver used.

Hex head/Socket self-tapping screws: Contractors typically use hexagonal head screws in heavy-duty applications where a countersunk head is not required.

Button head, dome head, and pan self-tapping screws: Self-tapping screws with button heads, dome heads, and pan heads are commonly used in carpentry. The dome shape reduces the possibility of the screw head countersinking into the material.
