Our “Flat washers” family has been designed to ensure secure fastening over time for all assembly challenges. They are used in threaded assemblies for distribution of load on a greater surface. They are also used for oversized or oblong holes and for protection of assembled parts.

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