Frequently Asked Questions
Q: What are the specifications for NF 000021 hex lock nut?
A: NF 000021 is a hex lock nut in 1/4-20 size with a dimpled nylon insert. The zinc plated (zp) finish provides corrosion resistance for gravity conveyor and material handling equipment.
Q: What equipment uses the NF 000021 nut?
A: This nut is compatible with gravity conveyor systems, accumulation tables, and frame assemblies from manufacturers like Hytrol, Honeywell, and Daifuku. Verify 1/4-20 bolt specifications on your equipment before ordering.
Q: What does dimpled mean on the NF 000021?
A: Dimpled refers to the nylon insert design inside the nut. The dimples grip the bolt threads to prevent loosening from vibration and movement, which is critical in conveyor systems.
Q: When should I replace the NF 000021 nut?
A: Replace when the nylon insert becomes worn, stripped, or when the nut no longer holds tension on the bolt. Inspect during routine conveyor maintenance if vibration or noise increases.
