LOCKWASHER
Frequently Asked Questions
Q: What is the OM30405 lockwasher used for on manual pallet jacks?
A: The OM30405 lockwasher is a fastener component that prevents bolts and screws from loosening due to vibration during pallet jack operation. It is used on handle assemblies, wheel brackets, pump connections, and other critical joints.
Q: Which manual pallet jack models use the OM30405 lockwasher?
A: The OM30405 lockwasher is compatible with standard manual pallet jacks from Crown, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify bolt diameter and application location match your equipment before ordering.
Q: What is the material composition of the OM30405 lockwasher?
A: The OM30405 lockwasher is typically zinc-plated steel for corrosion resistance. The plating provides protection in both indoor and outdoor environments. For food-grade or stainless steel applications, confirm material compatibility with your equipment specifications.
Q: How often should OM30405 lockwashers be inspected or replaced?
A: Inspect lockwashers every 12 months or after heavy use. Replace if the washer is bent, broken, or damaged. If the bolt or screw it secures becomes loose more than once, replace both the fastener and the lockwasher.
Q: What happens if the OM30405 lockwasher is not used on critical fasteners?
A: Without a lockwasher, bolts and screws can gradually loosen from vibration, leading to rattling, misalignment, safety hazards, or equipment failure. Always use lockwashers on wheel brackets, handle joints, and pump connections to maintain structural integrity.
