Connecting two sheets of stainless steel material can be problematic for a number of reasons. Self-drilling screws can help to solve some of these issues and DD Fasteners Bi-Metal can supply these essential components in a game-changing format made using two types of steel.

Self-drilling screws are referred to by various names including stitching screws, roofing screws and Tek screws. At DD Fasteners Bi-Metal , we can supply self-drilling screws made from Grade 304 stainless steel which feature an innovative point made using hardened carbon steel.

The hardened points of these screws act in a similar way to a drill bit and are thus able to cut directly through a stainless steel sheet. They can be used for up to two sheets of stainless steel with a thickness of 1mm each for a total thickness of 2mm and are also suitable for use with Grade 316 cladding or sheet.

All of our bi-metal screws undergo extensive and diverse testing and quality control procedures to ensure premium quality. Find out more about these procedures on our website ,  contact our expert technical team for further information and advice.
