Among the essential components in fastening assemblies, plain washers play a critical role. Plain washers, known for their straightforward design and functionality, are thin, flat, and circular pieces usually made from metal or plastic. They are placed between the bolt or screw head and the surface being fastened, or between the nut and the fastening surface. Their primary functions include distributing the load of the fastener, protecting surfaces from damage, and preventing loosening due to vibration.
