Professional Applications & Engineering Value
This spring lock washer delivers exceptional engineering value through its 18-8 stainless steel composition and innovative top and bottom serrated design. The dual-sided serrations bite into both the fastener and bearing surface, creating superior resistance to vibration-induced loosening in demanding applications. The corrosion-resistant properties make it ideal for automotive assemblies, industrial machinery, marine equipment, and outdoor structures where environmental factors would compromise ordinary washers. With Rockwell C38 hardness, it maintains structural integrity under repeated stress cycles, while the precise dimensions ensure proper fitment for both 5/8" and M16 fasteners. This combination of features solves critical challenges in vibration-prone environments, reducing maintenance frequency and preventing equipment failure.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications including 0.669" ID, 0.945" OD, 0.051" thickness, and 0.083" overall height. Manufactured from 18-8 stainless steel with Rockwell C38 hardness rating, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The dual-sided serration pattern provides enhanced locking performance for both inch (5/8") and metric (M16) fastener systems in industrial applications.
