Self Tapping Screws

Self-tapping screws are a type of fastener designed to create its own internal thread as it is driven into a material, such as metal, wood, or plastic. Unlike traditional screws that require a pre-drilled hole, self-tapping screws have a sharp, pointed end and special threading that allows them to cut through and tap their own threads into the material.

Self-tapping screws are widely used in industries such as construction, automotive, electronics, furniture assembly, and general DIY projects. They are particularly useful in applications where quick and efficient fastening is required, or where pre-drilling may be impractical or time-consuming.  Self-tapping screws offer several advantages. They simplify the fastening process by eliminating the need for pre-drilling. They provide strong and secure connections, as the threads formed are specific to the screw itself. Self-tapping screws also have high pull-out resistance and can be easily removed and reinstalled if needed.

We stock them in a variety of heads, CSK slotted, CSK pozi, pan pozi, pozi flange, pan slotted, and hex. Finishes include zinc and stainless.

Diameter measurement differs from other screw types, and they are measured in No. Gauge with a corresponding metric (mm) equivalent. We stock them in No2 (M2.2), No4 (M2.9), No6 (M3.5), No8 (M4.2), No10 (M4.8), No12 (M5.5) No14 (M6.3). The length is measured in imperial inches.
