LOCKWASHER
Frequently Asked Questions
Q: What is a lockwasher and where is it used in a manual pallet jack?
A: A lockwasher is a split or toothed ring that prevents fastener rotation and loosening under vibration. In manual pallet jacks, lockwashers are used under bolt or screw heads on the pump assembly, load wheel axles, and handle pivot points to maintain secure connections during repeated lifting and lowering cycles.
Q: What material is this lockwasher made from and will it corrode?
A: This lockwasher is typically made from hardened steel with a zinc or phosphate coating for corrosion resistance. The coating protects against rust in standard warehouse and outdoor environments. However, prolonged exposure to salt water or harsh chemicals may degrade the coating over time.
Q: Is this lockwasher compatible with Crown, Toyota, and Raymond manual pallet jacks?
A: This part is compatible with most manual pallet jacks from Crown, Toyota, Raymond, Yale, and similar OEM manufacturers. Verify the fastener diameter and bolt hole dimensions match your specific equipment model before ordering.
Q: How often should lockwashers be replaced?
A: Lockwashers do not wear out in normal use but should be inspected during routine maintenance. If a bolt or screw is found loose during service, replace the lockwasher when re-tightening the fastener. If the lockwasher is damaged, deformed, or corroded, replace it immediately.
Q: What size is this lockwasher?
A: SKU 244442-12900-71 is sized to fit standard metric or fractional fasteners used in manual pallet jack assemblies. Contact us with the bolt or screw diameter from your equipment if you need dimension confirmation.
