Product Description

Heavy-Duty Self-Drilling Fixing For Steel

The 5.5X40MM SS Hex HS Selfdrill Bi-Metal Washered Self-Drilling Screw A2 is a premium fastening solution engineered for fast and secure fixing into steel sections up to 12mm thick. Designed with a bi-metal structure that pairs a hardened carbon steel drill point with an A2 stainless steel body, this screw delivers exceptional performance in both drilling speed and corrosion resistance. It’s an ideal choice for outdoor or exposed applications such as steel cladding, façade installations, and metal roofing, even in aggressive environments.

The hexagonal head ensures strong drive control, while the pre-assembled stainless steel washer with bonded EPDM seal prevents water ingress and delivers a tight, leak-free finish. With no pre-drilling required, installation is streamlined—saving time and labour costs on-site. Its robust self-drilling tip is precision-designed to penetrate up to 12mm thick steel, making it suitable for heavy-duty structural or industrial applications where consistent, reliable performance is essential.

This high-quality bi-metal screw offers peace of mind with long-term resistance to rust and wear, helping reduce maintenance and improve the longevity of steel assemblies in exposed conditions.
