Uss Flat Washer 5/8" Zinc Plated

Hillman USS Flat Washer 5/8" Zinc Plated

The Hillman USS Flat Washer is a general-purpose washer that sits under a bolt head or nut to spread the clamping force over a wider area. Sized for a 5/8" bolt, it protects the material surface from damage and marring and helps the joint seat evenly. This gives a more secure connection that is less likely to loosen or pull into the surface under load. It is made to the USS pattern, which has a wider outer diameter and a larger bore than the SAE pattern. The extra width spreads the load across more surface and helps bridge slightly oversized, rough or elongated holes, which makes it a common choice for general construction, framing and heavy repair work. It is stamped from low-carbon steel with protective zinc plating that resists rust and corrosion for dependable indoor and light outdoor use, and it keeps a clean, uniform silver finish.
