Lock Nut 5/8-11
SAF-Holland

Specialized lock nut for 5/8-11 inch threaded assemblies provides a reliable anti-loosening solution in heavy-duty trailer hardware. The part is sized to mate with standard 5/8-11 fasteners and uses a locking mechanism designed to resist loosening in high-vibration environments typical of highway operation. Finishes include zinc plating to resist corrosion from road salts and weather exposure. The VMRS category places it among locking fasteners used with industrial trailers, with code 053-007-035. Category 42594 identifies it as part of the locking nut family used across multiple SAF-Holland applications, including couplers, brackets, and suspension connections. When installing, technicians ensure the mating surface is clean and free of debris, apply the appropriate torque, and verify secure fit after initial movement tests. The labeling adheres to safety warnings (P65) to inform operators of standard precautions during handling and installation.
