Professional Applications & Engineering Value

This 18-8 Stainless Steel square washer is engineered to solve critical challenges in industrial assemblies, such as corrosion-induced failure and uneven load bearing. Its square shape provides a larger surface area than round washers, effectively distributing pressure and reducing the risk of material indentation or bolt slippage in high-vibration environments. The corrosion-resistant properties make it ideal for outdoor, marine, or chemical exposure applications, extending equipment lifespan. With precise dimensions tailored for 3/4" screw size, it ensures secure fastening in structural frameworks, heavy machinery, and construction projects, delivering reliable performance where durability and precision are paramount.

Specification Summary & Compliance

This washer features an inner diameter of 0.813", width of 2", and thickness range of 0.112-0.128", manufactured to inch system standards for consistent fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. The Rockwell B84 hardness confirms its mechanical robustness, suitable for demanding industrial use without compromising on environmental safety.
