Frequently Asked Questions
Q: What are the thread specifications and size of the LF 20218 lock nut?
A: The LF 20218 is a hexagonal lock nut with metric ISO threads M14 x 2.0 mm pitch. The nut measures 22 mm across flats. These specifications are standard for Lift-Rite L-55 series frame and axle assemblies.
Q: What grade and material is the LF 20218 lock nut?
A: The LF 20218 is Grade 8 carbon steel with a minimum Rockwell hardness of C35. It features an industrial phosphate coating for corrosion resistance. The heat-treated construction ensures the nut resists vibration loosening in manual pallet jack frame assemblies.
Q: What is the cross-reference part number for the LF 20218 lock nut?
A: The LF 20218 is cross-referenced as LR20218. Both SKUs are equivalent and interchangeable when replacing worn or damaged lock nuts in Lift-Rite manual pallet jack assemblies.
Q: Why is the LF 20218 a Grade 8 lock nut instead of a standard nut?
A: Grade 8 fasteners have higher tensile strength and hardness than standard grades. In pallet jack frame and axle assemblies, the lock nut resists vibration loosening under repetitive loading and lateral forces. The upgraded grade prevents critical fastener failure during warehouse operations.
Q: Which Lift-Rite pallet jack models use the LF 20218 lock nut?
A: The LF 20218 is used in Lift-Rite L-55 series manual pallet jacks. Alternate model designations include L55 and L 55. Check your equipment documentation to verify that this nut size and grade match your specific model.
