• Precise fit for 2" screws with a 2.062" inner diameter, ensuring secure fastening and reducing installation errors.
• Robust thickness range of 0.220-0.280" for optimal stability and vibration resistance in demanding construction and mechanical setups.
• Compliance with global regulations, including RoHS 3 and REACH, making it safe for use in regulated industries without environmental concerns.
• Versatile inch system compatibility for seamless integration with standard industrial equipment and fastener systems.

Professional Applications & Engineering Value

This heavy-duty square washer is engineered to address common challenges in industrial settings, such as uneven load distribution and fastener loosening under dynamic loads. The zinc-plated steel material offers excellent corrosion resistance, crucial for outdoor or humid environments like construction sites and machinery assemblies. Its square shape provides a larger bearing surface compared to round washers, effectively spreading force and preventing sinkage into soft materials. With a Rockwell B40 hardness, it maintains structural integrity under high stress, reducing the risk of failure in critical applications. Ideal for use with 2" screw sizes in structural frameworks, heavy equipment, and mechanical systems, this washer ensures reliable, long-lasting performance while meeting stringent industrial standards.

Specification Summary & Compliance

This square washer features precise dimensions with an inner diameter of 2.062" and thickness range of 0.220-0.280", adhering to standard inch system tolerances for consistent fit. Manufactured from zinc-plated steel, it complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and is REACH (EC 1907/2006) compliant, ensuring environmental and safety standards are met for industrial use.
