Frequently Asked Questions

Q: What fastener sizes does lockwasher 220019745 fit on manual pallet jacks?
A: Lockwasher 220019745 is designed for use with standard bolts and nuts on manual pallet jack assemblies. The washer dimensions match specific bolt sizes commonly used in frame assembly, wheel retention, load pin fastening, and mast components. Verify the bolt diameter on your assembly matches this washer specification before ordering. Contact us with your equipment model for size confirmation.

Q: What material and construction makes lockwasher 220019745 effective in vibration environments?
A: Lockwasher 220019745 is a hardened steel split lock design. The split lock mechanism creates a spring force between the bolt and mating surface, preventing fastener loosening under vibration and dynamic loads. Hardened steel construction resists deformation from repeated stress cycling. The conical split design provides consistent clamp force retention without relying on friction alone, making it ideal for high-vibration applications.

Q: Where are lockwasher 220019745 typically used on pallet jack equipment?
A: Split lock washers are used under bolt heads and nuts at critical fastening points on manual pallet jacks: wheel assembly bolts, load pin fasteners, mast guide roller retention, frame connection bolts, and pump coupling fasteners. Any assembly point subject to vibration during operation benefits from split lock washers. Proper placement is directly under the bolt head or nut bearing surface for maximum effectiveness.

Q: How does lockwasher 220019745 compare to other fastener retention methods?
A: Split lock washers like 220019745 provide vibration resistance superior to flat washers, equal or better performance than plastic loc-washers, and lower cost than thread-locking compounds. Split locks do not require special tools or solvents for removal, making maintenance simpler than adhesive compounds. However, they are less effective than nylon-insert locknuts in extreme vibration conditions. For pallet jack service, split lock washers are the industry standard for fastener retention.

Q: Can lockwasher 220019745 be reused after fastener removal?
A: Split lock washers lose spring tension and clamping force after initial use. Reusing a lockwasher that has been removed and reinstalled provides reduced vibration retention compared to a new washer. For critical fastening points on pallet jacks, replacement with new lockwashers is recommended whenever fasteners are removed. Inspect the washer for permanent deformation or cracks before reuse. In high-vibration applications, always use new split lock washers.
