CHAMFERD WASHERS – ISO 7090

ISO 7090 Chamfered Washers are specially designed flat washers with a beveled or chamfered edge on one side, intended for use with high-strength structural bolts and assemblies. The chamfer matches the bearing surface under bolt heads or nuts, ensuring full contact and even load distribution. This design reduces stress concentrations, prevents edge damage, and maintains joint integrity in heavy-duty applications.

At National Fasteners, our chamfered washers are manufactured with precise dimensional accuracy and superior surface finish, conforming strictly to ISO 7090 standards. They are ideal for applications in structural steelwork, bridges, heavy machinery, and other load-critical assemblies.
