Direct From Factory M16 Spring Wave Washer – Steel – Zinc Plated – DIN 137B – Pkg of 50

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.
