Frequently Asked Questions
Q: What does the 2501-105829 lockwasher do in a pallet jack assembly?
A: The 2501-105829 lockwasher prevents fasteners from loosening due to vibration, shock, and movement during pallet jack operation. It is placed under the bolt head or nut to maintain fastener preload and reduce the need for frequent retightening.
Q: What fastener sizes does the 2501-105829 lockwasher accommodate?
A: The 2501-105829 is designed for pallet jack industry-standard fastener sizes. Verify the bolt or stud diameter at your assembly location to ensure proper fit before ordering.
Q: Is the 2501-105829 compatible with different pallet jack brands?
A: Yes. The 2501-105829 is compatible with manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other major manufacturers. Match the washer inner diameter to your fastener size for correct installation.
Q: How do I know if the 2501-105829 lockwasher needs to be replaced?
A: Replace the 2501-105829 if it shows permanent flattening, loss of tension, cracks, or severe corrosion. If fasteners at that location repeatedly loosen during normal operation, the lockwasher has likely lost its clamping force and should be replaced.
