Stainless Steel Flat WashersFlat washers are a thin, flat, circular stamping with a centrally located hole, made from 18-8 austenitic stainless steel. Designed for use with stainless steel screws and nuts in general applications where parts are subject to corrosion. These general purpose commercial standard flat washers are positioned under a nut, head of a screw, or head of a bolt in order to provide a smooth bearing surface and evenly distribute the fastener load over a wider area.Detailed Product InformationSelect Desired Washer Size In Drop Down Menu To View Full Detailed .General Product InformationNominal Washer Size | Outside Diameter | Thickness Minimum | Thickness Maximum
