Lock Nut - 1 25 7
SAF-Holland

The engineering of this lock nut targets high-load lockage in suspension systems that experience frequent dynamic forces and vibration. With a thread size of 1 1/4-7 in, it is designed to maintain preload under fluctuating torque, ensuring that critical fasteners remain secured during vehicle operation. The design integrates with the trailer axle and suspension family, providing dependable performance in harsh operating environments typical of long-haul transport and distribution fleets. Its application extends to securing components such as mounting brackets, control arms, and joint interfaces where rotational play cannot be tolerated. VMRS code 053-007-035 anchors this part in the vehicle maintenance and repair domain, signaling its role in upholding structural integrity of suspension assemblies. Cross references to HLD 93400502 and TDA R304421 enable replacement planning and compatibility checks across related part numbers, supporting efficient inventory management and service planning. In practice, this lock nut helps reduce maintenance cycles by maintaining consistent clamp force, minimizing wear on mating surfaces, and contributing to predictable alignment and road-handling performance.
