M12 Lock Nut

Frequently Asked Questions

Q: What is the thread specification for the ML M12-1.75-NUT?
A: The ML M12-1.75-NUT is an M12 x 1.75 lock nut. The M12 designation indicates a 12mm nominal diameter, and 1.75 refers to the metric pitch (1.75mm thread advance per rotation). This coarse-pitch metric specification is standard across Crown, Toyota, Raymond, and Yale material handling equipment.

Q: What equipment types use M12 lock nuts like the ML M12-1.75-NUT?
A: M12 lock nuts are commonly used in hydraulic cylinders, mast assemblies, pump connections, and steering linkages on electric pallet jacks, walkie stackers, and sit-down forklifts from manufacturers including Crown, Toyota, Raymond, Hyster, and Yale. Verify your equipment manual or existing fastener to confirm fit before ordering.

Q: What material is the ML M12-1.75-NUT made from?
A: Lock nuts of this specification are typically manufactured from hardened steel with a nylon insert or deformed-thread design to provide vibration resistance. The exact material composition (carbon steel, alloy steel, or stainless) depends on the original equipment specification. Contact us with your equipment model for material details.

Q: How often should the ML M12-1.75-NUT be replaced?
A: Lock nuts are typically replaced when they become loose, stripped, or corroded, or during major overhauls. Nylon-insert lock nuts may lose effectiveness after repeated removal and reinstallation. If you are removing and reinstalling a nylon-insert lock nut multiple times, replacement is recommended to maintain vibration resistance and prevent accidental loosening.

Q: Is the ML M12-1.75-NUT compatible with the ML M12-1.75X55-BOLT?
A: Yes. The ML M12-1.75-NUT is designed to thread onto the ML M12-1.75X55-BOLT and other M12 x 1.75 bolts. Both fasteners share the same metric pitch and thread class, making them compatible assemblies for equipment assembly and maintenance.
