Frequently Asked Questions
Q: What are the material specifications for the 25808001 helical spring lock washer?
A: The 25808001 is manufactured from SAE J403 medium carbon steel (SAE 1050 grade or equivalent) with vibration-resistant properties. This material provides the necessary hardness and elasticity to maintain bolt tension under dynamic loads in pallet jack systems and prevents fastener loosening.
Q: Which pallet jack assemblies and equipment types use the 25808001 lock washer?
A: This spring lock washer is used in manual pallet jack assemblies from brands including Crown, Toyota, Raymond, Yale, and other OEM manufacturers. It secures critical load-bearing hardware such as wheel pivot bolts, handle assemblies, and hydraulic cylinder fasteners. Verify your equipment model number before ordering.
Q: What standards and certifications does the 25808001 conform to?
A: The 25808001 helical spring lock washer conforms to ANSI B18.21.1 standards for helical spring lock washers, ensuring consistent material properties, dimensional accuracy, and load retention specifications across manufacturers.
Q: What is the typical lifespan and maintenance requirement for this spring lock washer?
A: A properly installed spring lock washer provides continuous service life in pallet jack assemblies. Replace if you observe corrosion, permanent deformation, or loss of tension during routine inspections. In high-moisture environments, inspect annually for rust and replace preventively if degradation is visible.
Q: How does the vibration-resistant property of the 25808001 differ from standard lock washers?
A: The vibration-resistant design of the 25808001 uses precise helical coil geometry to maintain constant tension on fasteners as equipment operates. This prevents bolt loosening caused by repetitive motion and load cycling in manual pallet jack systems, extending hardware life and improving safety.
