Professional Applications & Engineering Value

This heavy-duty split lock washer delivers critical vibration resistance in demanding industrial applications where mechanical fasteners face constant stress and movement. The 18-8 stainless steel construction provides excellent corrosion resistance in harsh environments, while the standard split design creates continuous spring tension that compensates for thermal expansion, material relaxation, and vibration-induced loosening. Engineered to ASME B18.21.1 standards, this washer ensures reliable performance in heavy machinery, structural assemblies, and equipment subjected to dynamic loads. The combination of Rockwell C35 hardness and precise dimensional control makes it ideal for applications requiring repeated disassembly and reassembly without performance degradation.

Specification Summary & Compliance

This split lock washer features precise dimensions of 1.914" ID x 2.811" OD with 0.422" thickness, manufactured to ASME B18.21.1 standards for dimensional accuracy and performance. The washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. Designed specifically for 1 7/8" screw applications in inch measurement systems, it maintains consistent quality and reliability in vibration-prone environments.
