LOCKWASHER
Frequently Asked Questions
Q: What is lockwasher SKU 321789 designed for?
A: Lockwasher 321789 is a fastener component used in manual pallet jack assemblies to prevent bolt loosening under vibration and load cycling. It is compatible with most manual pallet jack models from Crown, Toyota, Raymond, Yale, and Hyster.
Q: What material is lockwasher 321789 made from?
A: Lockwasher 321789 is typically manufactured from hardened steel with a split ring or toothed design to provide mechanical locking action. This material resists corrosion and maintains locking tension even in humid or wet warehouse environments.
Q: Does lockwasher 321789 need replacement during routine maintenance?
A: Lockwasher 321789 should be inspected annually during maintenance cycles. Replace it if you observe permanent deformation, rust, or loss of tension. A compromised lockwasher can lead to bolt creep and mechanical failure of critical assemblies.
Q: What bolt sizes does lockwasher 321789 fit?
A: Verify the inner diameter and thickness of lockwasher 321789 against your equipment documentation or existing fasteners before ordering. Incorrect sizing will not provide locking action and can result in assembly failure.
Q: Can lockwasher 321789 be reused after removal?
A: Lockwashers are typically single-use components. After removal, the mechanical deformation reduces locking effectiveness. Order replacement washers to ensure proper fastener security in rebuilt assemblies.
