Flat Washers
Willie Washer is a leading manufacturer of flat washers, offering precision-engineered components for a wide range of industrial applications. Round flat washers are the most common type of washers, and they have the most uses. Common uses include spanning oversized holes, distributing loads over wider areas, preventing surface damage, and avoiding embedment from nuts and bolts. Round flat washers also provide a consistent surface for more predictable joints and can serve as shims to compensate for tolerance variations.
