5/8" Hardened Bevel Washer - 11/16" I.D. - Hardened Steel - Plain - F436 - ASTM A325 - 25 Pk

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.

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.

Hard Steel Flat Washers are used to increase the surface area of fasteners in order to more evenly distribute the force applied when fasteners are tightened to a surface. They are intended to be used in conjunction with Grade 5 and Grade 8 bolts and nuts. Common applications for hard steel washers include industrial, MRO, manufacturing and oil & gas.
