Frequently Asked Questions

Q: What material is lockwasher 50019971 made from?
A: SKU 50019971 is manufactured from hardened high-carbon steel equivalent to SAE 1074 or SAE 1050 hardened spring steel. The hardness rating is Rockwell C38-C45, providing superior resistance to loosening under vibration and fastener torque cycles in manual pallet jack assemblies.

Q: Which manual pallet jack brands and models use lockwasher 50019971?
A: SKU 50019971 is compatible with manual pallet jack assemblies from Crown, Toyota, Raymond, Yale, Hyster, and equivalent manual pallet jack platforms. Verify fastener diameter on your specific model before ordering to confirm fitment.

Q: Why is lockwasher 50019971 better than a standard washer?
A: Unlike flat washers, the lockwasher design prevents fasteners from loosening due to vibration during load handling. The hardened steel construction maintains clamping force longer, reducing maintenance frequency and improving assembly reliability in manual pallet jack operations.

Q: What fastener diameter does lockwasher 50019971 fit?
A: Contact us with your equipment model number or fastener size for exact inner diameter specifications. SKU 50019971 is designed for manual pallet jack fastener applications; precise sizing ensures proper bearing and clamping.

Q: How often should lockwasher 50019971 be replaced?
A: Hardened steel lockwashers do not require routine replacement if correctly torqued during assembly. Inspect periodically for deformation or corrosion. Replace if fasteners repeatedly loosen or if the washer shows permanent deformation.
