Flat / Plain Washer
A plain washer, or flat washer, is a basic and circular metal piece with a central hole. Its purpose is to evenly distribute the weight of a threaded fastener, such as a bolt or screw, across a larger surface.
Fender Washer
The fender washer is specifically designed for use on thin sheet metal. It stands out with its larger outer diameter relative to its center hole and is made from a thinner gauge metal compared to typical flat washers.
Spring Washer
Unlike flat washers, spring washers have a curved or angled shape that allows them to exert a spring force and prevent loosening caused by vibrations or thermal expansion
External Tooth Lock Washers
External Tooth Lock Washers are a type of lock washer featuring multiple outward-facing teeth (serrations) around the outer edge.
Internal Tooth Lock Washer
Internal tooth lock washers have teeth on the inner edge which secure the bolt or screw by gripping its surface, thus preventing any loosening caused by vibration or shock.
Square Washers
Square Washers are flat washers with a square outer shape and a central round hole.
Serrated Washer
A serrated washer is a type of lock washer designed with ridges or serrations either on one or both surfaces.
