This included two washers, a nut and bolt and a sealing washer of rubber, cork or fibre sheet.
Why Are Washers Used?
The primary purpose of most washers is to evenly distribute the load of the threaded fastener with which they are used. Threaded fasteners stress the material in which they are driven. Driving a screw into wood, for example, may cause the wood to crack around the surface.

What Are Fender Washers?
