Custom Flat Washer Manufacturer
Flat washers are flat, ring-shaped components installed beneath a bolt head or nut to increase the bearing area and distribute clamping force across the mating surface. Their inner diameter, outer diameter and thickness determine the fit around the fastener and the contact area available for load transfer.
As a flat washer factory in China, we produce standard and custom flat washers according to customer drawings, samples and dimensional requirements. Production can be specified by ID, OD, thickness, tolerance, material, hardness, flatness and surface finish, with standard configurations available to applicable specifications such as DIN 988
