Professional Applications & Engineering Value
This bronze split lock washer delivers critical engineering solutions for industrial applications where vibration-induced fastener failure is a primary concern. The bronze material with Rockwell B90 hardness provides excellent wear resistance while maintaining the spring properties necessary for effective locking action. The split design creates constant spring tension against both the fastener and bearing surface, effectively resisting rotational loosening in heavy machinery, power transmission systems, and industrial equipment. The ASME B18.21.1 standard compliance ensures dimensional accuracy and reliable performance across various 1/2" screw applications, making it ideal for maintenance, repair, and OEM applications where consistent locking performance is essential.
Specification Summary & Compliance
This split lock washer features precise inch system dimensions: 0.512" inner diameter, 0.869" outer diameter, and 0.125" thickness, designed specifically for 1/2" screw size applications. Manufactured to ASME B18.21.1 specifications for standard split lock washers, it ensures proper fit and function. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making it suitable for use in regulated industries and international markets.
