Flange Cup Washers and Back Up Washers are used as spring retainers and locators, centering washers, housings for assemblies, a substitute for larger heavier washers, as spacers to reduce material usage and weight product, end caps, anti-tampering protection for fasteners, and for many other reasons.

Flange Cup Washers generally have a greater overall height than Back Up Washers and therefore the cup portion is deeper.

We will help you define your need and select the appropriate-size washer from our tool library of cup washer dies—or we will design to your unique specifications.

You can specify Flange Cup Washers and Back Up Washers made of Steel, Stainless Steel, Aluminum, Copper, Brass and other malleable metals.
