Evolution Bi-Metal stainless steel TEK-5 self-drilling tek screws are specifically designed for fixing into aluminium sheeting and panels from 4.0mm to 12.5mm thick. The 16mm EPDM washer creates a waterproof seal, making these ideal for securing roofing panels and exterior cladding.

Stainless steel fasteners are required when fixings aluminium sheeting or into aluminium substrates.
