Bi-Metal Wing Drill screws for light steel are specifically designed for fastening timber, composite panels, aluminium sheeting, and cladding materials directly to light gauge steel sections without the need for pre-drilling. The integrated wings on the screw create a clearance hole through the timber or panel before snapping off once the drill point reaches the steel, allowing the thread to engage securely into the steel substrate without damaging the material surface.

Manufactured using bi-metal technology, these screws combine a hardened carbon steel drill point for fast drilling performance with a stainless steel body that provides excellent corrosion resistance and long-term durability, making them ideal for external and high-moisture environments. They are commonly used in roofing, façade systems, steel frame construction, and timber-to-steel fixing applications where reliable performance and a clean finish are essential. To install, simply drive the screw directly through the material into the steel section using a suitable drill driver at the recommended RPM speed until a secure fixing is achieved.
