This washer is made from A2 stainless steel with a flat Form A profile to suit M20 bolts or set screws. It is typically installed between the nut or bolt head and the surface material, distributing load to minimise local deformation and maintain joint security.
The corrosion-resistant material makes it appropriate for outdoor and damp site conditions. Commonly used in structural connections, general construction, machinery assembly, and repair, it offers a reliable solution for both light and heavy-duty fastening tasks where an even load spread is required.
