Lock Nut - 1/8, Grade B
SAF-Holland

This precision fastener assembly is engineered for durability in demanding heavy duty suspension applications. Constructed from steel with a defined thread size of 1 inch, it provides reliable preload retention and resistance to loosening under constant vibration and dynamic load typical of heavy trucks and buses. The design aligns with the NEWAY AS Series and targets the Truck and Bus Suspensions family, delivering a robust fastening solution for critical joints where secure locking is essential. By resisting self-loosening and maintaining clamping force over time, this component helps protect hub assemblies, mounting brackets, and linkage connections from play, uneven wear, and potential misalignment. Its steel composition offers a balance of strength, fatigue resistance, and reusability in service intervals, contributing to safer axle operation and reduced maintenance downtime. VMRS code 053-007-035 categorizes this item within the vehicle maintenance and repair segment, signaling its role in securing suspension connections. Cross references to HLD 93400502 and TDA R304421 provide compatibility guidance for replacement planning and stocking strategies, ensuring technicians can source appropriate equivalents without compromising performance. Category context places it among suspension fasteners, where precise thread engagement and reliability are paramount for long service life.
