Metallics N173 – Frequently Asked Questions
1) What thread size are the Metallics N173 hex nuts?
The N173 is a 7/8-9 hex nut, meaning a 7/8 inch nominal diameter with 9 threads per inch, which is the standard UNC coarse pitch for 7/8 inch. It mates with 7/8-9 threaded rod, anchor bolts, or hex bolts of the same thread. It will not run onto 7/8-14 fine thread.
2) Will these 7/8-9 nuts work on 7/8 inch threaded rod for trapeze hangers and strut supports?
Yes. The N173 nut is 7/8-9, the coarse thread used on standard 7/8 inch all-thread rod, so it threads directly onto rod used for trapeze hangers, pipe and conduit supports, and strut assemblies. For bearing on slotted strut or thin material, pair it with a 7/8 inch flat washer so the load is not carried on the nut face alone.
3) Are the Metallics N173 nuts plated for corrosion resistance, and can I use them outdoors?
The N173 is a steel nut with zinc plating. Zinc gives general corrosion protection for dry interior and sheltered work. For sustained outdoor exposure, wet locations, or coastal and chemical environments, step up to hot-dip galvanized or stainless 7/8-9 nuts instead, since zinc plating is a thin sacrificial coating.
4) Is the N173 a plain hex nut or a heavy hex nut?
It is a standard hex nut in 7/8-9, not a heavy hex pattern. Hex nuts of this type are the general purpose choice for electrical support, equipment mounting, and bolted steel work. If a structural drawing calls out a heavy hex nut, the across-flats and thickness are larger and a plain hex nut is not a substitute.
5) How many nuts come in a box of Metallics N173?
The N173 ships as a 100 piece quantity, so one order covers a full run of hanger rod terminations or bolted connections rather than a handful. Each piece is identified by manufacturer part number N173.
6) What size wrench or socket do I need for a 7/8-9 hex nut?
A 7/8-9 finished hex nut takes a 1-5/16 inch wrench or socket across the flats. Keep that in mind for tight trapeze or in-wall work where socket clearance around the rod is limited.
