Frequently Asked Questions
Q: What is NF 000023 and what size is it?
A: NF 000023 is a hex lock nut in 5/16-18 size with a dimpled insert design. The dimples create friction on bolt threads to resist loosening in gravity conveyor applications.
Q: When should I use NF 000023 instead of NF 000022?
A: Use NF 000023 when high vibration or frequent disassembly is expected. The dimpled insert provides stronger lock-down than smooth nylon inserts and resists repeated assembly and removal better than standard nylon nuts.
Q: What conveyor systems use the 5/16-18 bolt size?
A: 5/16-18 bolts and NF 000023 nuts are common in mid-size gravity conveyor rollers, frame brackets, and guard attachments from manufacturers like Hytrol, Honeywell, and Daifuku. Verify bolt specifications on your equipment.
Q: How long does NF 000023 last in continuous use?
A: Dimpled lock nuts typically maintain secure locking for 1 to 2 years in continuous conveyor operation. Inspect regularly for signs of wear, corrosion, or bolt movement. Replace if the nut spins freely or loses tension.
