Professional Applications & Engineering Value

Our zinc-plated steel square washers deliver critical engineering solutions where standard round washers fall short. The 2.5" width and square configuration provide significantly larger surface contact area, effectively distributing clamping force and preventing material deformation in heavy-duty applications. The Rockwell B40 hardness ensures the washer maintains its structural integrity under sustained pressure, while the corrosion-resistant zinc plating protects against environmental degradation in manufacturing, construction, and machinery assembly. These industrial washers are specifically engineered for 1 1/4" screw systems where vibration resistance and long-term reliability are paramount, making them ideal for structural steel connections, equipment mounting, and high-stress mechanical assemblies.

Specification Summary & Compliance

This square washer features precise dimensional specifications including 1.312" inner diameter, 2.5" width, and thickness ranging from 0.110" to 0.140". Manufactured from zinc-plated steel with Rockwell B40 hardness, it conforms to inch system standards for North American industrial applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use across global industrial markets.
