Professional Applications & Engineering Value
This split lock washer delivers critical vibration-resistant performance for demanding industrial applications where mechanical fastening integrity is paramount. The zinc-plated steel construction provides essential corrosion resistance while maintaining the Rockwell C38 hardness necessary for sustained locking force in machinery, equipment assembly, and structural frameworks. Engineered specifically for 7/16" screw size applications, the 0.45" internal diameter ensures precise fitment, while the split design creates continuous spring action that compensates for thermal expansion, material relaxation, and dynamic loading conditions. The ASME B18.21.1 standard compliance guarantees dimensional accuracy and performance reliability across manufacturing, construction, and maintenance operations where vibration-induced fastener failure poses significant operational risks.
Specification Summary & Compliance
This standard split lock washer features precise inch system dimensions with 0.45" ID, 0.776" OD, and 0.109" thickness, manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for international industrial markets with strict material restrictions.
