Flat Washers

Round flat washers are the most common type of washers supplied and they have the most uses. They are used to span oversized holes, and can spread loads over wider areas. They prevent surface damage and embedment from nuts and bolts, and provide a consistent surface for more predictable joints. They can also be used as shims to compensate for tolerance variations.

Willie Washer stocks over 60,000 different special washers for same day shipments. Check our inventory for various sizes, shapes, materials and finishes.
