Product Description

High Strength Bi-Metal Screw for Steel Applications

The 5.5x38mm LS SS Hex Self-Drill Bi-Metal Screw is designed for fast and efficient installation into steel materials up to 4mm thick. This A2 stainless steel screw features a hardened carbon steel drill point, delivering fast penetration without the need for pre-drilling. It’s the ideal choice for installers needing precision, corrosion resistance, and long-term performance.

Engineered for structural and panel applications, the screw includes a dual-thread configuration—one to grip into structural steel and the other beneath the head to prevent deformation of lighter gauge materials. Designed for use with cordless impact drivers, it enables quick, safe installations in demanding site conditions.

Whether you're fixing cold-formed steel, sheeting, or composite panels, this hex head screw delivers dependable hold and clean drive-through in every use.
