LOCKWASHER
Frequently Asked Questions
Q: What is the HW-1293 lockwasher used for in manual pallet jacks?
A: The HW-1293 lockwasher prevents fastening bolts and screws from loosening due to vibration and repetitive cycling in manual pallet jack equipment. It provides a secondary locking mechanism on critical mechanical joints and assemblies.
Q: Which manual pallet jack models use the HW-1293 lockwasher?
A: The HW-1293 lockwasher is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and similar manufacturers. Lockwashers secure fasteners at load wheel assemblies, handle joints, pump components, and articulation points. Verify the bolt diameter matches your equipment before ordering.
Q: What is the inside diameter of the HW-1293 lockwasher?
A: The HW-1293 lockwasher accommodates a specific bolt or stud diameter for manual pallet jack applications. Confirm the inner diameter matches your fastener size. Using an incorrectly sized lockwasher will not prevent bolt loosening.
Q: Does the HW-1293 lockwasher work with stainless steel or galvanized bolts?
A: The HW-1293 lockwasher functions with various bolt materials including carbon steel, stainless steel, and galvanized fasteners. Material compatibility is not a limiting factor for lockwasher performance. The locking mechanism depends on mechanical tooth or spring design, not material reactivity.
Q: When should the HW-1293 lockwasher be replaced?
A: Replace the HW-1293 lockwasher whenever a fastener fails to maintain tension or if the washer becomes flattened, cracked, or deformed. Do not reuse lockwashers after fastener removal. Standard maintenance includes periodic bolt checks on all equipment assemblies to catch loosening before component failure occurs.
