About Plain Flat Washers

Plain flat washers are thin, flat, circular metal discs with a central hole that fits around a bolt or screw. They are primarily used to distribute the load of a fastener, reducing the stress on the material being fastened and preventing damage to the surface. Plain flat washers also help in preventing loosening of the fastener by providing a smooth bearing surface, ensuring a more secure and stable connection.

At Teshi Fasteners, our plain flat washers are manufactured with precision from high-quality materials to ensure exceptional performance and longevity. Available in materials such as carbon steel, stainless steel, and alloy steel, our plain flat washers meet various industry standards and specifications.
