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. These tek screws are made from AISI A304 stainless steel and are then electro zinc plated to give extremely good resistance to rust. Stainless steel fasteners are required when fixings aluminium sheeting or into aluminium substrates.

  • Coarse self-tapping thread for extreme grip & excellent pull out
  • Manufactured from AISI A304 stainless steel
