Flat washers are the most widely used types of general purpose washers. Most often paired with standard bolts and hex nuts. They distribute the force from the bolt head and nut over a larger area which serves to protect the surface of the material you are working with.

Flat washers are great for adding resistance to your bolts and screws to prevent them from boring into the wood and weakening it. These SAE fine threaded washers are finished with zinc to be corrosion resistant and designed to fit other fine fit bolts and washers. When selecting a washer, be sure to pick one that matches the fasteners you are already using. Picking a different finish may cause a chemical reaction, weakening your fasteners over time.
