Product Description

Stainless Steel Self-Drilling Screw for Secure Metal Fixings

The 5.5x32mm LS SS Hex Self-Drill Bi-Metal Washered Screw is designed for high-performance fixing into metal substrates up to 4mm thick. Manufactured from A2 stainless steel with a hardened carbon steel cutting tip, this bi-metal screw ensures fast and reliable penetration without pre-drilling. The integrated washer provides a tight, secure seal, ideal for preventing water ingress and panel deformation.

With dual thread zones—one for solid metal connection and one under-head thread to prevent panel crushing—this screw is suited for steel construction, sandwich panels, and cold-formed section installations. It’s engineered for ease of use with cordless impact drivers and features a sharp drill tip for consistent starts without slipping.

Perfect for professional metal construction projects, this screw meets the demands of precision, corrosion resistance, and ease of application.
