Bi-Metal Hex Head screws for heavy steel are specifically designed for fastening metal sheets, cladding systems, roofing panels, and construction components directly into heavy gauge steel sections without pre-drilling. Engineered with a high-performance self-drilling point, these screws provide fast and reliable installation in demanding structural and industrial applications where strong fixing performance is essential.

Manufactured using advanced bi-metal technology, they combine a hardened carbon steel drill point for exceptional drilling capability with a stainless steel body that delivers outstanding corrosion resistance and long-term durability in external environments. The hex head design allows for secure torque transfer and easy installation using a suitable hex socket driver. Commonly used in roofing, façade systems, steel framing, and heavy steel construction, these screws are ideal for projects requiring high strength, weather resistance, and dependable long-term performance.
