Lock Nut, 0.625, 11
SAF-Holland

Lock nut rated at 5/8-11 inches and designed for Grade as part of heavy trailer axle and suspension hardware, this component provides prevailing-torque characteristics to resist vibration-induced loosening. The lock-nut function is particularly important in high-dynamic environments where constant movement, torsional forces, and track irregularities threaten fastener integrity. VMRS code 053-007-035 situates this item within the locking hardware subset used across trailer and suspension assemblies, ensuring compatibility with other fasteners and ease of replacement during routine maintenance. Category context 42594 indicates its specialized role in securing critical mounting points and components subjected to oscillations from braking, cornering, and variable payloads. Cross-references, such as TDA R302983, may appear in certain fleets or catalogs to verify substitution options or coordinated fastener kits. In application, this lock nut contributes to long service intervals, reduces downtime due to retorquing needs, and maintains consistent clamping forces for safer vehicle operation and durable suspension performance.
