Professional Applications & Engineering Value

Engineered for demanding industrial washer applications, this zinc-plated steel square washer addresses critical challenges in machinery assembly, structural frameworks, and equipment manufacturing. The 0.219" ID precisely accommodates No. 10 screws, eliminating bolt hole mismatch while the square configuration provides superior resistance to rotational forces. The Rockwell B40 hardness ensures the washer maintains its structural integrity under vibration and heavy clamping pressures, preventing joint failure in heavy-duty applications. Combined with the corrosion-resistant zinc plating, this washer delivers long-term reliability in environments exposed to moisture, chemicals, and temperature variations, making it ideal for automotive, construction, and industrial machinery applications where fastener failure is not an option.
