Metal Washer Fasteners are often used in conjunction with threaded fasteners. Before a threaded fastener like a screw is driven into a surface, a washer may be placed through the end. 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. The washers are round outer diameter thin plates with a center hole punched to the size of the bolt or screw. The offered Metal Washer Fasteners are made for being used in various industries and applications.
