Plain washers are designed to evenly distribute the load of a threaded fastener and provide a more secure connection.
They help to avoid surface damage and reduce friction during tightening and loosening. During their use, plain washers ensure structural reliability by providing a buffer that maintains joint tension and protects surfaces from wear and tear.
