Find Washers by Specification or See our Directory of Suppliers. There are many different types of washers for a variety of applications. Lock washers are used to secure fasteners. Spring washers are a load bearing device that provides a preload between two surfaces. Other common types include flat washers, C-washers, D-shaped washers, countersunk or finishing washers, fender washers, SAE washers, torque washers, and shoulder washers.
In some cases, the washer is also to allow for easier turning of the bolt head or nut. If the nut digs into the material a bit, it will be hard to turn, and possibly damage the material if it is turned anyway. The washer decouples the turning motion of the nut from the material.
