What are Tapping Screws?
Tapping screws are designed to join 2 pieces of sheet metal together.
Self Tapping screws were first used in the early 1950s, when they were used in sheet metal.
Our tapping screws are also known as sheet metal screws. These have a sharp Type “A” thread with a moderately sharp gimlet point. The threads are widely spaced. Sheet metal screws are used in thin gauge metal.
The material being fastened is light gauge steel and is often soft. The holes in the material are usually pre drilled or pre punched.

They work by piercing holes in thinner gauge metal.
These screws are sometimes called thread forming screws. As the screws are being installed, they form their own mating thread when joining 2 pieces of metal.
This allows for disassembly and reassembly.
If the material is too thick, then self drilling screws are needed.
While our tapping screws were not made for wood due to the thread design, in some applications they can be used in wood. However, if they are, then a small pilot hole might be necessary due to the hardness of the wood. Do not overtighten. They can strip out because some grades of wood are hard.
They can also be used in plastic in some cases.
