Frequently Asked Questions
Q: What are the diameter and thickness specifications for the 22730 washer?
A: The 22730 is a flat washer designed for manual pallet jack bolt and screw assemblies. Verify the outer diameter, inner diameter (bore size), and material thickness against your equipment documentation. Using incorrect washer size will result in loose connections or fastener pull-through.
Q: Which manual pallet jack models use the 22730 washer?
A: This washer is compatible with manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Confirm the bolt size and fastener type match your equipment assembly before ordering multiple units.
Q: What material is the 22730 washer made from and is it corrosion-resistant?
A: The 22730 is typically manufactured from zinc-plated steel or stainless steel for corrosion resistance in wet and outdoor environments. Zinc-plated washers are suitable for general use, while stainless steel offers superior durability in aggressive chemical or saltwater conditions. Verify the material specification for your application.
Q: Why do washers need replacement on manual pallet jacks?
A: Washers wear when bolts vibrate loose or when corrosion compromises the surface finish, allowing fasteners to shift. Once a washer is bent, cracked, or corroded, it cannot distribute load evenly and must be replaced. Deformed washers allow bolt head or nut to pull through and cause structural failure.
Q: Can the 22730 washer be used with different bolt sizes?
A: No. The 22730 is designed for a specific bolt diameter. Using it with oversized or undersized bolts will result in improper load distribution and fastener failure. Always match the washer bore size exactly to the bolt diameter on your pallet jack.
