Product Description
The WASHER-1250 lock washer is a hardened steel fastening component designed to prevent nuts and bolts from loosening due to vibration and operational stress on manual and electric pallet jacks. This direct replacement lock washer features a split design that creates resistance and maintains fastener tension throughout equipment operation. Ideal for securing wheel assemblies, axle connections, pump linkage bolts, and frame connections on pallet handling equipment. Manufactured from durable, hardened steel with superior resistance to deformation under load, ensuring consistent locking performance and extended service life. A cost-effective solution for maintaining safe, reliable pallet jack operations across warehouse, dock, and material handling environments.
Frequently Asked Questions
Q: What is a lock washer and why is it used on pallet jacks?
A: A lock washer (WASHER-1250) is a fastening component that prevents nuts and bolts from loosening due to vibration, movement, or operational stress on manual pallet jacks. It sits between the fastener head and the surface, creating resistance that locks the fastener in place during equipment operation.
Q: Where is the WASHER-1250 lock washer typically installed on a pallet jack?
A: Lock washers like the WASHER-1250 are installed on manual pallet jack fasteners that experience vibration and movement, including wheel assemblies, axle connections, pump linkage bolts, and structural frame connections. They sit directly under bolt heads or nuts to prevent fastener rotation.
Q: What material is the WASHER-1250 lock washer made from?
A: The WASHER-1250 is manufactured from hardened steel designed to withstand operational stress and maintain tension over extended use. The metal construction resists deformation under load and provides consistent locking performance throughout the pallet jack life cycle.
Q: How does a lock washer compare to a standard flat washer?
A: Unlike a standard flat washer that only distributes load, a lock washer (WASHER-1250) includes a split, internal teeth, or helical design that actively resists fastener rotation. This prevents loosening caused by vibration and movement during pallet jack operation.
