Clamping Fasteners

Machine Washers

Machine washers are precisely toleranced intermediate plates that distribute the compressive clamping force of a threaded fastener across a broader surface area. By reducing localized contact stress, they prevent deformation of the mating substrate and mitigate the risk of fastener embedment. Fabricated from diverse materials including hardened steel, brass, and polymers, these components are ubiquitous in structural engineering, fluid sealing systems, and electromechanical assemblies requiring load management or galvanic isolation.
