Spring Washers Are Formed In An Irregular Shape To Provide Lighter Resistance And Distribute Pressure In Low Strength Fastening. Spring Washers compress to act like a spring and deflect when loaded, providing a preload between the two joined surfaces. Fasteners are used where assemblies need a part to eliminate rattle, maintain assembly tension, compensate for expansion or contraction, or to absorb intermittent shock loads for long lasting durability.

Countersunk Finishing Washers have a recess design that prevents the fastener from splitting or stripping the work piece material for added durability. Hardware is made of high quality steel for long lasting reliability.
