Metallics N1653M – Frequently Asked Questions
1) What thread size is the Metallics N1653M hex nut, and what bolt does it fit?
The N1653M is a 3/8-16 hex nut, so it mates with 3/8 inch diameter threaded rod, bolts, or screws cut to 16 threads per inch. Note that the standard UNC coarse thread for 3/8 inch is 3/8-16, which is what you will find on common strut rod and anchor bolts.
2) Will a 3/8-16 hex nut work with 3/8 inch threaded rod for hanging conduit and strut?
Yes. Threaded rod in 3/8 inch for hanger and trapeze work is cut 3/8-16, which is the thread on the N1653M, so it runs on standard 3/8 inch rod. Pair it with a 3/8 inch flat washer or a channel nut where you need bearing surface against strut or a hanger flange.
3) Is the Metallics 3/8-16 hex nut plated, and can it be used in damp locations?
It is steel with a zinc plating (the St-Zn in the description). Zinc plating handles indoor and dry or occasionally damp interior work such as strut, conduit hanger, and panel mounting. For sustained wet, exterior, or corrosive exposure, specify a hot-dip galvanized or stainless nut instead.
4) How many nuts come in the Metallics N1653M package?
One N1653M carton holds 3,000 pieces of the 3/8-16 zinc plated steel hex nut. That is a bulk electrical-trade pack, sized for shops consuming 3/8 inch hardware continuously on strut and hanger work, not a counter pack of a few dozen.
5) Is this a hex nut or a flange/lock nut?
The N1653M is a plain hex nut, no flange and no nylon insert or locking feature. If the assembly sees vibration and you need it to stay put, add a lock washer or move to a locknut; a plain hex nut alone relies on torque and the mating surface.
6) Is the Metallics N1653M sold in one configuration only?
Yes, it comes one way: model N1653M, 3/8-16 zinc plated steel hex nut in the 3,000 piece pack. There are no finish or size choices under this number, so if you need 1/4-20 or 1/2-13, that is a different Metallics part.
