Products / Self-Tapping Screws

Self-Tapping Screws
They cut their own thread — and hold it.

Designed for materials where pre-tapped holes aren't practical. The hardened thread profile cuts a mating thread in light-gauge metal, plastic or wood as the screw is driven, creating a tight, vibration-resistant joint.
