Frequently Asked Questions
Q: Why is copper used for washers on pallet jacks?
A: Copper washers provide excellent electrical conductivity, corrosion resistance, and a soft surface that prevents damage to fasteners and the components they contact. Copper is also non-magnetic and resists rust in humid or wet environments.
Q: Is the DA B120-97 copper washer compatible with Dayton 4YX97 pallet jacks?
A: Yes, the DA B120-97 copper washer is designed for use with Dayton model 4YX97 pallet jacks. It fits specific fastener sizes on these units. Confirm the inner diameter and outer diameter match your equipment before ordering.
Q: What is the purpose of a copper washer in pallet jack assembly?
A: The copper washer distributes fastener load over a wider surface area, prevents fasteners from sinking into softer materials, provides electrical grounding continuity in some applications, and resists corrosion better than steel washers in wet or salt environments.
Q: When should copper washers be replaced?
A: Replace copper washers if they become corroded, if fasteners are loosening repeatedly in the same location, if the washer surface is flattened or work-hardened, or if the fastener is sitting lower than it should be in the assembly.
Q: How long do copper washers typically last?
A: Copper washers are durable and typically last the operational life of the equipment under normal conditions. They resist corrosion better than steel. Replacement is usually driven by fastener service rather than washer degradation.
