Shop Cup Washers

Cup washers are formed washers that come in a range of styles. We provide a wide array of forms to suit the specific type you need: formed flat-sided cup washers, cup washers with flanges or flat rims to fit into recesses or holes, and even countersunk washers to be used with flat head or oval head screws and bolts. Our selection of cup washers feature a flanged design to distribute weight on a wide variety of surfaces. 

This type of washer may be utilized to shield large holes in applications where plumbing lines are required. Cup washers can also be used as spring retainers, centering washers, tamper proofing, and as finishing washers. A countersunk cupped washer is engineered to provide insulation for various types of configurations. Contractors make use of these components for support or decorative applications.

Cup washers and countersunk washers are offered in materials such as Low Carbon Steel, Brass, Copper, Spring Steel, and Stainless Steel. Willie Washers offers cupped washers with finishes such as Zinc & Clear, Zinc & Yellow, Phosphate & Oil, Black Oxide, or Zinc & Black. Browse our large selection of cup washers, countersunk washers, fender washers, and terminal cup washers to find a product that meets your needs and demands. Give our team a call by phone at (847) 956-1344 or fill out our Contact Form if you have questions or concerns about our selection of cup washers.
