Frequently Asked Questions

Q: What is the A179 lock nut used for in pallet jack assemblies?
A: The A179 is a standard lock nut component used in manual and electric pallet jack wheel and bearing assemblies. It secures axle shafts and prevents wheel movement or drift during operation and storage.

Q: What material is the A179 lock nut made from?
A: The A179 is manufactured from hardened steel with a nylon insert or similar locking mechanism to maintain tension and prevent self-loosening under vibration and repeated use.

Q: Is the A179 compatible with different pallet jack brands?
A: Yes. The A179 is a standard metric or imperial lock nut size used across manual pallet jacks from Crown, Toyota, Raymond, and other common OEM manufacturers. Verify the specific diameter and thread pitch for your equipment.

Q: How often does the A179 lock nut require replacement?
A: Replace the A179 if it becomes stripped, corroded, or if the nylon insert is worn and no longer holds tension on the axle. In high-use environments, inspect lock nuts during routine maintenance intervals.
