Spring Washers

Spring washers, also known as split washers, are made of highly elastic material and are a single circular fastener component with a hole in the center, commonly used in a variety of mechanical devices. It provides uniform pressure and tension in bolt assemblies and can effectively prevent loosening and wear of bolts and nuts under thermal expansion and contraction, vibration, and dynamic loads to maintain a solid connection.

51Fasteners provides spring washers in full sizes, various coatings and materials. We can customize spring washers according to your drawings.
