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.

External Tooth Lock Washers secure bolt heads or nuts to increase the bearing area and offer greater hardness so that the nut or bolt can be rotated without distortion of the bearing surface. Hardware is constructed of high quality steel for long lasting durability.

3/8-16X1 3/4 Slotted Indented Hex Washer Thread Cutting Screw Type F Fully Threaded Zinc. Thread-Cutting Type-F threaded screws are used in heavy gauge sheet metal, aluminum, zinc and lead die castings, cast iron, brass and plastic. In stainless steel, material into which the screw is to cut threads should have a lower hardness by 10-20 Rockwell hardness. Indented hex washer head offers advantages of hex head, plus greater protection to mating surface.
