Frequently Asked Questions

Q: What Crown pallet jack models does the CR 060005-004 lock washer fit?
A: The CR 060005-004 lock washer is designed for Crown M Series Stacker pallet jacks. Verify your equipment matches the M Series Stacker model before ordering. If you are unsure of your Crown model or need to confirm compatibility with an alternate series, contact our parts team with your serial number.

Q: What fastener sizes does the CR 060005-004 lock washer accommodate?
A: Confirm the fastener diameter on your Crown M Series Stacker. The CR 060005-004 is sized for a specific bolt or screw diameter. Provide your exact fastener size or equipment serial range to our parts team to ensure you receive the correct lock washer variant.

Q: Why use a lock washer instead of a standard flat washer on pallet jacks?
A: Lock washers prevent fasteners from backing out due to vibration and repeated load cycles from pallet jack operation. The CR 060005-004 provides positive mechanical locking action, maintaining fastener tension in critical assembly joints where loose bolts could cause equipment failure or safety hazards.

Q: How often should lock washers be inspected on Crown M Series Stackers?
A: Inspect fasteners and lock washers during regular maintenance intervals. Replace the CR 060005-004 if you observe fasteners loosening repeatedly, visible corrosion, or permanent deformation of the locking mechanism. Preventive replacement every 2 to 3 years is recommended in heavy-duty operations.

Q: What material is the CR 060005-004 lock washer manufactured from?
A: The CR 060005-004 is manufactured from hardened steel for superior vibration resistance and durability in pallet jack assembly environments. Steel construction resists corrosion and maintains locking tension under the thermal cycling and mechanical stress of material handling operations.
