What Is a Thru Hard Washer?

Hard washers are much like traditional washers in shape and size, but they have been hardened through special chemical processes for enhanced toughness and durability. There are different types of construction-grade and military-grade hard washers to choose from, but they all provide similar levels of performance.

Applications of Hard Washers

Hard washers provide added strength that you won’t get from traditional washers. They are used in applications that involve intense weight or levels of exposure to heat. In these cases, the added hardness is an important characteristic to ensure strength and stability.

USS vs. SAE Thru Hard Washers

To be considered hard washers, the washers must meet certain standards and requirements. SAE hard washers meet requirements as laid out by the Society of Automotive Engineers, while USS washers adhere to United States Standard requirements. You’ll find both options when you browse our selection of thru hard washers.
