Hillman Zinc-Plated Steel 3/4 in. SAE Flat Washer 20 pk 953 Wide Temperature Range: 105 -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. *
