USS hardened flat washers are great for adding resistance to your bolts and screws to prevent them from boring into the wood and weakening it. 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.
