Product Description

Reliable Bi-Metal Screw for Secure Steel Fixings

The 5.5x38mm LS SS Hex Self-Drill Bi-Metal Washered Screw is engineered for consistent and secure fixings into steel substrates up to 4mm thick. Its bi-metal construction combines an A2 stainless steel body with a carbon steel drill point, delivering corrosion resistance alongside effective drilling performance without the need for pilot holes.

Designed with a hex head and integrated washer, this screw offers a tight, sealed fit, preventing leaks and minimising panel damage. The dual thread profile ensures optimal clamping while avoiding surface indentation on panels. Ideal for use with sandwich panels, cold-formed sections, and structural metalwork, it is impact driver compatible and suitable for outdoor or damp environments.

For contractors and installers seeking speed, reliability, and durability, this screw provides excellent performance in demanding conditions.
