Meeting Your Manufacturing, Material, And Quality Requirements

Numerous factors affect the quality and long-term performance of flat washers. As a U.S.-based manufacturer and an ISO 9001:2015 certified company, we assure you that all parts we ship are manufactured domestically. We offer metal washers made from a diverse range of materials, including conventional options like copper stampings, aluminum washers, and stainless steel washers (which can include passivation). We also specialize in plastic washers and exotic materials like Inconel, Nylatron washers, and Monel. Additionally, we can quote a variety of platings including zinc, cad yellow, and black ox to suit your specific needs.
