Product Description

High-Performance Bi-Metal Self-Drilling Screw

The 5.5 X 38MM HS SS Hex Selfdrill Bi-Metal Washered Self-Drilling Screw A2 is a premium fastening solution designed for secure fixing into steel without the need for pre-drilling. Its bi-metal composition features a hardened carbon steel drill point for efficient penetration, seamlessly fused with an A2 stainless steel body that offers outstanding corrosion resistance—making it ideal for external cladding, roofing and façade applications in harsh environments.

The hexagonal head with pre-assembled stainless steel washer and bonded EPDM seal ensures a watertight finish while distributing pressure evenly to prevent damage to surfaces. This screw is perfect for use in applications requiring high pull-out strength and rust protection, even in coastal or industrial locations. Quick to install with a secure bite into substrate, it helps reduce installation time and long-term maintenance costs.

Whether used in construction, fabrication or renovation projects, this self-drilling screw offers long-term reliability and performance in demanding conditions.
