Lock Nut C9967
SAF-Holland

Lock nut variant identified by code C9967 provides a secure, vibration-tolerant fastener option for SAF-Holland installations. This locking nut is designed to resist loosening from dynamic motion and road shocks, helping maintain alignment and joint stability in critical assemblies. It belongs to the same family as other component-level fasteners and uses standard M12-compatible threads, aligning with corresponding bolts and hardware. The zinc protective finish adds corrosion resistance for long-term field performance in varied climates. VMRS 053-007-035 roots it in the lock-nut segment of hardware, while category 42837 places it in a specialized sub-portfolio of locking fasteners used on trailers and suspension components. In practice, technicians ensure correct thread engagement and mating surface preparation, then torque to specification to maintain structural integrity. The packaging includes the standard safety labeling (P65). This part is selected when reliability under vibration is essential and where standardized replacement parts are required for fleet maintenance.
