Lockwasher

Frequently Asked Questions

Q: What is the purpose of a lockwasher in manual pallet jack assemblies?
A: The lockwasher prevents fasteners from loosening due to vibration and repetitive load cycling. It creates a locking action under the bolt head or nut, which is critical for manual pallet jacks that experience constant shock loads during operation and transport.

Q: Which manual pallet jack models use SKU 9040102582?
A: This lockwasher is compatible with standard manual pallet jacks from Crown, Toyota, Raymond, and Yale. Verify the fastener size and mounting location on your specific model before ordering to ensure correct fit.

Q: What material is this lockwasher made from?
A: Lockwashers for material handling equipment are typically zinc-plated steel or stainless steel. Zinc-plated versions offer corrosion resistance suitable for indoor and moderate outdoor use, while stainless steel provides superior durability in wet or cold storage environments.

Q: How often should lockwashers be replaced?
A: Lockwashers should be inspected during regular maintenance and replaced whenever fasteners are removed and reinstalled. If a bolt or nut is found loose during inspection, replace the lockwasher immediately to prevent further loosening.
