LOCKWASHER
Frequently Asked Questions
Q: What is a lockwasher and why is it used on manual pallet jacks?
A: A lockwasher is a fastener component that prevents bolts and screws from loosening due to vibration and equipment movement. On manual pallet jacks, lockwashers secure critical assembly points like wheel mounts, handle connections, and frame joints.
Q: Which manual pallet jack models use the 137413 lockwasher?
A: The 137413 lockwasher is compatible with standard manual pallet jack models from Crown, Toyota, Raymond, Yale, and similar manufacturers. Confirm the bolt diameter and fastener type required by your equipment before ordering.
Q: What material is the 137413 lockwasher made from?
A: The 137413 lockwasher is typically manufactured from hardened steel with a zinc or nickel plating to resist corrosion. The material provides the spring tension needed to maintain fastener tightness under operational stress.
Q: How often should I replace lockwashers on a manual pallet jack?
A: Lockwashers do not require routine replacement under normal conditions. Replace them only if fasteners repeatedly loosen, if the washer shows permanent deformation, or if flattening reduces its effectiveness. Inspect during regular maintenance.
Q: Can the 137413 lockwasher be reused after equipment disassembly?
A: Lockwashers lose effectiveness after repeated compression cycles. If equipment is disassembled, use new lockwashers during reassembly to ensure reliable fastening and prevent loosening during operation.
