Lock Nut, 0.75, 10
SAF-Holland

Lock nut with 3/4-16 inch thread and a 10 designation is designed to provide secure, vibration-resistant fastening in trailer axle and suspension assemblies. The prevailing-torque feature helps resist loosening under repeated start-stop cycles, steering inputs, and road irregularities typical of heavy-duty service. VMRS code 053-007-004 places this part within the standard set of suspension and axle locking hardware, enabling accurate maintenance documentation and fast part replacement in catalogs and workstation systems. Category 42590 emphasizes its role as a core component in secure mounting arrangements for suspension linkages and associated brackets. The lock nut interacts with matching bolts and washers to maintain consistent preload, reduce the risk of joint fatigue, and support safe, predictable handling across varying payloads and road conditions.
