Professional Applications & Engineering Value

This zinc-plated steel square washer delivers critical engineering advantages in demanding industrial applications, where corrosion and mechanical stress are common challenges. The zinc plating provides a protective barrier against moisture and chemicals, significantly reducing rust and extending component lifespan in outdoor or high-humidity settings. With its 2" square shape and substantial 0.220-0.280" thickness, it effectively distributes clamping force over a wider area, preventing surface indentation and fastener pull-through in structural assemblies, machinery bases, and heavy equipment. The Rockwell B40 hardness ensures the washer maintains its form under heavy loads, while the precise 0.938" ID guarantees perfect fitment with 7/8" screw sizes, eliminating misalignment issues in critical fastening systems.

Specification Summary & Compliance

This square washer features inch system dimensions with a 0.938" inner diameter, 2" width, and thickness range of 0.220-0.280".
