2501-109000

Frequently Asked Questions

Q: What material is the 2501-109000 lockwasher made from?
A: The 2501-109000 is manufactured from hardened steel with a Rockwell C35 minimum hardness rating. It is a split lock washer design with plain steel finish, uncoated. The hardened steel construction provides superior vibration resistance compared to standard lockwashers.

Q: Why is the 2501-109000 hardened steel split lock washer used instead of regular lockwashers?
A: The 2501-109000 hardened steel split lock design delivers enhanced vibration resistance and maintains superior fastener preload under heavy-duty conditions. It is designed for manual pallet jack assemblies subject to continuous movement and shock loads during material handling operations.

Q: What fastener applications is the 2501-109000 lockwasher suited for?
A: The 2501-109000 is engineered for securing threaded fasteners in pallet jack lift mechanisms, frame assemblies, and mechanical linkages where vibration and dynamic loads are present. It is compatible with standard pallet jack fastener sizes across Crown, Toyota, Raymond, Yale, and other major manufacturers.

Q: When should the 2501-109000 lockwasher be replaced?
A: Replace the 2501-109000 if the split ends have separated, if the washer is permanently flattened, if cracks are visible in the hardened steel, or if fasteners at that location repeatedly loosen. Loss of elastic tension indicates the washer can no longer maintain preload effectively.
