What is A Self-Tapping Screw?

A self-tapping screw is a type of screw that taps and threads its own hole as it is installed. Different tapping styles are used with different materials. For example, self-tapping screws for metal utilize a gap in the continuity of the thread, which generates a flute and a cutting edge similar to those on a standard tap; self-tapping screws for wood or soft plastics often use a tip that tapers to a gimlet point, which forms a tap hole by displacing the surrounding material. Also known as self-drilling screws, these screws are offered in both imperial and metric sizing varieties.

Self-piercing screws are a variation of self-tapping screws that are specifically designed for use with sheet metal materials. These screws have the ability to self-pierce light gauge sheet metal and tap their own mating threads as they’re installed.

Sheet Metal Screws

Sheet metal screws are one type of self-tapping screw. They are ideal for applications with pre-drilled holes, and are fully threaded from under the head to the end of the thread. Value Fastener stocks Type A, Type AB, High-Low and Type B sheet metal screws. Most of our sheet metal screws are manufactured from 18-8 and 410 stainless steel. These stainless steel screws are available with a number of finish options; we offer clear zinc plated screws, black zinc plated screws, black oxide plated screws, green ceramic coated screws, among other options. We also offer several different head types, including flat head steel metal screws and hex head metal screws. 

High-Low self-tapping screws have double lead threads where one thread is high and the other low, which provide easier penetration into the substrate. The high threads are sharper than conventional threads, which causes less displacement of material as the screw is driven in; consequently, less effort is required to drive in High-Low self-tapping screws. The low threads, which run between the high threads, increase the screws’ contact with the substrate material for a stronger grip and increased resistance to pullout and vibrational loosening.
