Metallics JN163JBR – Frequently Asked Questions
1) What thread size is the Metallics JN163JBR jam nut?
The JN163JBR is a 1/4-28 hex jam nut, so it mates with 1/4 inch fine-thread (UNF) rod, screws, or threaded studs. A 1/4-20 coarse thread will not engage it.
2) How many nuts come in a jar of Metallics JN163JBR?
Each jar holds 100 of the 1/4-28 hex jam nuts. The jar pack keeps them from scattering in a van drawer or on a service cart, which is why electricians buy small fasteners this way rather than loose.
3) What is a hex jam nut used for instead of a standard hex nut?
A jam nut is a thinner hex nut, used either as a locking nut tightened against a standard nut, or where there is not enough clearance behind a panel or fitting for a full-height nut. The JN163JBR covers the 1/4-28 fine thread version of that job. If you need the primary load-carrying nut, use a full hex nut and keep the jam nut as the locker.
4) Is the Metallics JN163JBR the right nut for threaded fixture stems and small electrical studs?
Yes, where that hardware is 1/4-28. Fine-thread 1/4 inch studs show up on lighting fixture stems, terminal studs, and small machine assemblies, and a jam nut is what you run on top to lock the adjustment without adding height. Confirm the stud pitch is 28 TPI and not 20 before ordering.
5) What is the Metallics part number to order for a 1/4-28 jam nut?
Order Metallics JN163JBR. That is the manufacturer part number and the only model on the item, supplied in a 100 count jar.
