Frequently Asked Questions
Q: What is the purpose of the MF450405 lock washer in manual pallet jacks?

Q: What material and design does the MF450405 lock washer use?
A: The MF450405 lock washer features a split or tooth design manufactured from hardened steel. This design provides positive locking force while distributing load evenly across the fastener surface.
Q: How often should the MF450405 lock washer be replaced?
