Lock Washer for Pallet Jacks

Frequently Asked Questions

Q: What is the material composition of lock washer A000031311?
A: Lock washer A000031311 is manufactured from hardened steel with zinc plating. The design features internal or external teeth that create friction and mechanical locking to prevent bolt loosening under vibration.

Q: Which fastener sizes is lock washer A000031311 compatible with?
A: Verify bolt diameter and thread pitch match the washer specifications before ordering. This lock washer fits standard fastener applications across pallet jacks, lift trucks, and material handling equipment from major OEM brands.

Q: Does lock washer A000031311 provide adequate vibration resistance?
A: Yes. The tooth or spring design prevents fastener rotation under normal warehouse vibration and equipment operation. However, fasteners in high-vibration environments may still require periodic tightness checks.

Q: How does lock washer A000031311 resist corrosion?
A: The zinc plating provides corrosion protection suitable for indoor warehouse, cold storage, and outdoor light-exposure use. In high-humidity or salt-spray applications, stainless steel lock washers offer superior corrosion resistance.

Q: When should lock washer A000031311 be replaced?
A: Replace lock washers if the teeth become flattened from repeated fastening cycles, if corrosion compromises the plating, or if the fastener they secure continues to loosen during equipment use. Typically, expect 5-8 years of service under normal conditions.
