USS Through Hardened: The “Wide Series” has a larger outside diameter that delivers increased bearing surface resulting in the best load distribution.
SAE Through Hardened: The “Narrow Series” has a smaller outside diameter and is best suited for those applications with a limited amount of space.
Our Through Hardened washers offer the highest strength for all applications.
USS and SAE carbon steel washers are stocked in plain, zinc clear, and zinc yellow.
We recommend using the biggest diameter washer that will fit the application.
