Professional Applications & Engineering Value
This split lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The black-oxide steel material provides superior corrosion protection while maintaining the necessary spring tension for reliable locking performance. The standard split lock washer design creates continuous upward pressure against the fastener head and downward pressure against the work surface, effectively preventing rotation and loosening. Particularly valuable in machinery assembly, automotive applications, and heavy equipment manufacturing, this ASME B18.21.1 compliant washer solves the persistent problem of maintenance-intensive fastener retightening. The precise 0.512" inner diameter ensures perfect compatibility with 1/2" screws, eliminating installation issues and reducing assembly time.
Specification Summary & Compliance
This industrial-grade split lock washer features precise dimensional specifications including 0.512" inner diameter, 0.733" outer diameter, and 0.172" thickness, engineered for optimal performance with 1/2" screw size applications. Manufactured to ASME B18.21.1 standards with Rockwell C38 hardness, it ensures consistent quality and reliable locking action. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
