Frequently Asked Questions
Q: What are the specifications of the NF 016187 shoulder bolt?
A: The NF 016187 is a 5/16 inch diameter shoulder bolt with a 0.410 inch shoulder diameter, zinc plate (zp) finish, and epoxy coating. This bolt is designed for gravity conveyor roller mounting and support brackets.
Q: What does the 0.410 dimension indicate?
A: The 0.410 inch measurement is the diameter of the shoulder (unthreaded shaft portion) of the bolt. This shoulder sits in the roller bore and provides precise alignment without requiring bushings in many standard gravity conveyor applications.
Q: What is the purpose of the epoxy coating on this bolt?
A: The epoxy coating provides corrosion and impact resistance in addition to the zinc plate base finish. This dual finish is common in food processing and cold storage conveyor systems to extend fastener life and prevent galling.
Q: Which roller brands does the NF 016187 fit?
A: The NF 016187 is compatible with gravity rollers from Hytrol, Intelligrated, Honeyville, and other OEM suppliers that specify 5/16 inch bolts with 0.410 inch shoulders. Verify bore diameter and bolt length match your roller before ordering.
Q: How long does the epoxy and zinc finish typically last?
A: The combination epoxy and zinc finish typically lasts 5 to 10 years in standard warehouse conditions. In high-humidity, salt-spray, or chemical environments, the finish may degrade within 2 to 3 years.
Q: What is the difference between NF 016187 and NF 016188?
A: The NF 016187 has a 0.410 inch shoulder diameter while the NF 016188 has a 0.296 inch shoulder diameter. Use the correct shoulder size to match your roller bore diameter. Undersized shoulders may cause rollers to slip; oversized shoulders may not fit.
