Frequently Asked Questions
Q: What is the specification for shoulder bolt NF 016157?
A: NF 016157 is a 5/16 inch diameter shoulder bolt with .410 inch shoulder length, zinc plated with epoxy coating. The epoxy coating provides enhanced corrosion resistance for gravity conveyor applications, particularly in wet or humid environments.
Q: What gravity conveyor equipment is NF 016157 compatible with?
A: NF 016157 fits gravity conveyor rollers and frame assemblies where 5/16 inch fastening is required. Verify your equipment documentation for exact mounting location and clearance before ordering, as shoulder length and epoxy finish must match your system specifications.
Q: What is the difference between NF 016157 and NF 016158?
A: NF 016157 has a .410 inch shoulder length, while NF 016158 has a .296 inch shoulder length. Both are 5/16 inch diameter with zinc plated epoxy coating. Choose the correct shoulder length based on your conveyor frame thickness and mounting hole depth.
Q: How long does the epoxy coating last on NF 016157?
A: The zinc plated epoxy coating provides protection for extended periods in normal conveyor environments. In wet or cold storage conditions, inspect fasteners annually for corrosion. Replace if coating is compromised or fastener shows rust development at the shoulder or thread.
Q: Can NF 016157 be reused if removed from a conveyor?
A: NF 016157 can be reused if the shoulder length is correct for your new application and the epoxy coating remains intact with no visible damage or corrosion. Inspect the shoulder area and threads carefully before reuse.
