Professional Applications & Engineering Value

This zinc-plated steel square washer is engineered to address critical challenges in industrial settings, such as uneven load distribution and fastener loosening under vibration. The 4" width and square shape maximize surface contact, effectively spreading force across a broader area to prevent joint failure and substrate deformation. Made from durable zinc-plated steel, it resists corrosion in demanding environments like construction, machinery assembly, and outdoor infrastructure. With a precise 1.562" ID tailored for 1 1/2" screw sizes, it ensures accurate alignment and secure fastening, reducing maintenance needs. The Rockwell B40 hardness further enhances reliability, making it ideal for heavy-duty applications where consistent performance and compliance with RoHS and REACH standards are essential for safety and regulatory adherence.

Specification Summary & Compliance

This square washer features an inner diameter of 1.562" and a width of 4", with a thickness range of 0.220-0.280" for precise fit in inch-based systems. It complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) standards, ensuring environmental and safety adherence. The Rockwell B40 hardness confirms consistent material strength, suitable for industrial fastening requirements without compromising on durability or regulatory compliance.
