Axle Nut
SAF-Holland

Operating within the hub assembly, this high strength axle fastener functions as the principal connection between the wheel end and the axle shaft. It must tolerate extreme torque, vibration, and thermal cycling generated by highway speeds and heavy payloads. In heavy haul and commercial trailer applications, correct torque specification and seating are essential to prevent hub loosening, bearing preload changes, or wheel separation. The VMRS code 053-007-035 denotes category and function within the wheel end assembly. This component works in conjunction with related sealants and locking hardware to ensure reliable service life under harsh conditions. The category context places it among trailer axle and suspension hardware, reinforcing its role in maintaining axle integrity. For compatibility, the part is selected to match standard trailer axle systems and is often paired with OEM and premium aftermarket equivalents. In maintenance, inspect for wear during routine checks, replace when threads show signs of deformation, and always adhere to proper wheel removal and reinstallation procedures. Proper preloading and re-torquing after initial road wear help preserve hub geometry and brake performance, leading to fewer unscheduled stops and reduced life cycle costs for the fleet.
