Frequently Asked Questions
Q: What is the purpose of the 85411 washer?
A: The 85411 is a standard flat washer for general fastener applications in pallet jacks and light-duty forklifts, including mast guide bolts, control panel mounting, and minor structural connections. It prevents bolt heads from cutting into softer material.
Q: What is the 85411 made from?
A: The 85411 is manufactured from plain carbon steel with a zinc-plated finish. The zinc coating provides moderate corrosion resistance suitable for indoor warehouse environments and light outdoor exposure.
Q: Is the 85411 compatible with electric pallet jacks?
A: Yes, the 85411 is compatible with electric and manual pallet jacks from Toyota, Crown, and Raymond. It is also used in entry-level sit-down forklifts from Yale and CAT. Confirm fastener diameter specifications for your specific equipment model.
Q: How long does the 85411 typically remain in service?
A: The 85411 provides 1,500 to 3,000 service hours under normal warehouse conditions. Service life depends on fastener torque and whether the equipment operates in dry storage or high-moisture environments.
Q: What maintenance or inspection is needed for the 85411?
A: The 85411 requires visual inspection during routine equipment servicing. Check for surface rust, flaking zinc coating, or permanent bending. Replace if the zinc plating shows active rust or if the washer has deformed and no longer distributes load evenly.
