Axle Nut, Outer, Parallel
SAF-Holland

The 01011009700Z Axle Nut, Outer, Parallel is a critical fastener that secures wheel hubs to the axle assembly. It is machined to exacting dimensions and paired with a locking mechanism or cotter pin to prevent loosening during heavy vibration and torque fluctuations. A parallel outer configuration ensures proper seating against the washer and hub face, promoting even clamping force and minimizing loosening risks under dynamic loads. Correct torque specification and thread engagement are essential for safety and wheel retention, while proper replacement ensures consistent wheel alignment and bearing load distribution. Inspect any signs of thread wear, deformation, or corrosion, and replace as part of routine maintenance to avoid wheel detachment or bearing damage. Source One Parts Center.
