Self-Tapping Screw – Countersunk

About Countersunk Self-Tapping Screws

Countersunk self-tapping screws are commonly used where a flush finish is required when fixing metal to metal. Once installed, the head sits level with the surface, making them ideal for applications where panels, brackets or plates need to sit flat.

All countersunk self-tapping screws in this category are designed for use with a pre-drilled pilot hole, allowing the screw to form its own thread cleanly in metal. This controlled installation helps improve accuracy and reduces stress on both the screw and the material.
