Extra thick flat plain washers provide a larger bearing area than standard washers, improving load distribution and reducing the risk of deformation under heavy clamping. They disperse pressure and protect mating surfaces, helping to maintain fastening stability in bolted assemblies.

Offered in carbon steel and stainless steel with multiple surface treatments, these plain washers cover a full range of sizes. Specify diameter and thickness when ordering to ensure the correct fit and finish. They are suited where increased bearing area or anti-deformation performance is required. Contact us to confirm availability of particular sizes or surface treatments.
