Frequently Asked Questions
Q: What is the purpose of a split helical lockwasher in manual pallet jacks?
A: This split helical lockwasher (OEM part 449002016) is a tempered spring steel component that prevents fasteners from loosening under vibration and repeated load cycles common in manual pallet jack operation. It provides constant spring tension against the bolt head or nut to maintain fastener tightness.
Q: What material is lockwasher 449002016 made from?
A: This lockwasher is manufactured from tempered spring steel with a plain, uncoated or light oil finish. The spring steel composition allows it to maintain consistent tension under load without permanent deformation, making it suitable for long-term fastener security in pallet jack assemblies.
Q: Which pallet jack models or brands use this lockwasher?
A: This OEM part 449002016 is compatible with manual pallet jack assemblies from major manufacturers including Crown, Toyota, Raymond, Yale, Jungheinrich, and other standard pallet jack brands. Always verify the part number matches your specific equipment model before ordering.
Q: Is this lockwasher single-use or reusable?
A: This lockwasher is intended for single-use installation. Once a fastener is secured and tightened, the spring steel lockwasher is permanently deformed and should not be reused. Replace with a new lockwasher whenever the fastener is removed and reinstalled.
Q: How long does this lockwasher remain effective?
A: A split helical lockwasher typically remains effective for the operational lifetime of the pallet jack when properly installed. However, corrosion, extreme vibration, or repeated fastener removal can degrade the lockwasher function. In harsh wet or salt environments, steel lockwashers may corrode and require earlier replacement.
Q: What is the exact specification and size of lockwasher 449002016?
A: For exact dimensions, bore size, and fastener compatibility specifications of part 449002016, contact our parts team with your pallet jack model and serial number. We can confirm the correct fastener pairing and provide measurement data to verify fitment.
