Frequently Asked Questions

Q: What is SKU 93930000 and what is it used for?
A: SKU 93930000 is an M8 split ring lock washer made from case-hardened carbon steel with a zinc-plated finish. It is designed to secure M8 metric fasteners in manual pallet jack assemblies by preventing fastener loosening due to vibration and repeated cycling.

Q: Where on a pallet jack would the 93930000 lock washer be used?
A: The 93930000 is used under M8 fastener heads at pivot points, wheel axles, steering connections, and structural frame joints on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM manufacturers. It secures critical load-bearing connections.

Q: What material is the 93930000 lock washer made from?
A: The 93930000 is manufactured from case-hardened carbon steel, which provides high tensile strength and spring force. The zinc-plated finish resists corrosion in humid warehouse and cold storage environments, extending service life compared to bare steel.

Q: How does the split ring design of 93930000 prevent fastener loosening?
A: The split ring creates continuous spring tension under the fastener head. When vibration or cycling attempts to loosen the bolt, the spring force of the split ring resists rotation and maintains clamping load, preventing fastener back-out and loss.

Q: Is the 93930000 lock washer appropriate for all M8 applications?
A: The 93930000 is suitable for M8 fasteners in vibration-prone applications typical of material handling equipment. For specialty applications requiring specific lock washer types such as tooth or serrated designs, verify your equipment specification before ordering.

Q: What is the typical service life of the 93930000 lock washer?
A: The zinc-plated case-hardened steel construction provides service life of 3000 to 5000 operating hours or longer if fasteners are properly torqued and the equipment operates in typical warehouse conditions. Corrosion risk increases in high-moisture environments, reducing effective lifespan.
