Washers often get thrown to the side or made into a game, but these unimpressive metal circles are more important than they are given credit for. They keep other fasteners in place against vibrations and impact. They keep surfaces from slipping against one another. Fastener Express has a selection of Black Oxide Stainless Washers to blend with dark-colored projects. Our washers are all weather resistant and high quality.
