Professional Applications & Engineering Value
This heavy-duty square washer addresses critical engineering challenges in industrial applications where standard washers fail. The 18-8 stainless steel composition delivers outstanding corrosion resistance in chemical processing, marine, and outdoor installations, while the square configuration prevents rotation during torque application. With its substantial 50mm width and 6.0mm thickness, this M10 metric washer effectively distributes clamping force across wider surfaces, preventing material deformation in structural assemblies, machinery bases, and heavy equipment. The precise 13mm ID ensures perfect alignment with M10 screws, reducing installation errors and maintenance requirements in high-vibration environments.
Specification Summary & Compliance
This square washer features metric dimensions with 13mm internal diameter, 50mm width, and 6.0mm thickness, manufactured from 18-8 stainless steel with Rockwell B84 hardness rating. The product conforms to international metric standards for M10 fasteners and maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
