Frequently Asked Questions
Q: What are the specifications of the NF 016188 shoulder bolt?
A: The NF 016188 is a 5/16 inch diameter shoulder bolt with a 0.296 inch shoulder diameter, zinc plate (zp) finish, and epoxy coating. It is used for gravity conveyor roller mounting and frame assemblies.
Q: What roller bore sizes does the 0.296 shoulder diameter fit?
A: The 0.296 inch shoulder is designed for rollers with bore diameters nominally in the 0.308 to 0.315 inch range, providing a precision fit without bushings. Measure your roller bore before ordering to confirm compatibility.
Q: Is the NF 016188 compatible with both plated and unplated rollers?
A: Yes. The NF 016188 works with both zinc-plated and unplated roller tubes. The zinc plate and epoxy finish on the bolt do not require matching finishes on the roller for proper fitment.
Q: Which conveyor brands use this smaller shoulder bolt?
A: The NF 016188 is used in gravity conveyors from Hytrol, Intelligrated, and Daifuku systems that specify smaller bore rollers. Confirm your roller bore diameter and conveyor model number to ensure correct fit.
Q: How do I know if I need NF 016187 or NF 016188?
A: Measure the roller bore (hole) diameter. If the bore is approximately 0.410 inch, use the NF 016187. If the bore is approximately 0.296 to 0.315 inch, use the NF 016188. Using the wrong shoulder diameter will cause fit issues.
