## Description

These washers are finished with a black ceramic coating and are designed to fit nuts and bolts of a similar size and finish. This black finish is designed to match the latest trends in black-finished hardware. When selecting a washer, be sure to pick 1 that matches the fasteners you are already using. Picking a different finish may cause a chemical reaction, weakening your fasteners over time.

• Perfect for interior, exterior, and decorative applications.
• Black ceramic coating provides lifetime corrosion resistance.
• Use with hex bolts, carriage bolts, or lag screws.
