About this item
Product details
The Hillman Flat washers are great for adding resistance to your bolts and screws to prevent them from boring into the wood and weakening it. These USS coarse threaded washers are finished with zinc to be corrosion resistant and designed to fit other coarse 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. These washers feature a steel material. 18 pack.
- Flat washers are used to increase the pressure a bolt or screw provides in material
- When selecting a washer, be sure to pick one that matches the fasteners you are already using.
- Prevents a nut, bolt, or screw of the same finish and size from pulling through material
- Designed for use specifically with screwing USS threaded bolts
- The zinc plating offers moderate protection against rust and corrosion while the steel material offers durability

Good quality and very useful.
I got these to make cowboy ornaments and they worked perfect as the cowboy hat brim on the bolts that I also got.
