Basic Cup Washers

Basic or Standard Cup Washers have the sides of the cup or dish bent at roughly 90 degrees. The basic cup washers are manufactured in a shape that allows for a variety of uses in an array of applications. Standard cup washers are used to cover bolts or nuts for safety or anti-tampering requirements. Cup washers are also used to compress insulation and sealant materials. Additionally cup washers are also utilized as spring retainers.

The important characteristics of a basic or standard cup washer are different depending on the uses. The inside cup dimension, the outside dimension, the height, and the material thickness are factors to consider when designing your cup washer. Cup washers are available in materials such as Low Carbon Steel, Spring Steel, Stainless Steel, Brass and Copper. Basic or standard cup washers are available in finishes such as Zinc & Yellow, Zinc & Clear, Galvanized, Black Oxide, Nickel, and Phosphate & Oil. Choose a cup washer material and finish that meets your needs. Basic and standard cup washers are designed to accommodate a variety of bolt sizes and uses.
