Our “Contact washers” family has been designed to ensure secure fastening over time for all assembly challenges. They prevent loosening of threaded assemblies due to vibration or temperature variations.

This family includes a complete range of products: some of them can be used separately, others have been designed to be assembled on a nut or a screw, they can ensure electrical continuity, etc.
