Metallics HHN14V – Frequently Asked Questions
1) What thread size and pitch is the Metallics HHN14V heavy hex nut?
The HHN14V is a 1/4-20 nut, so it threads onto 1/4 inch bolts, rods, or studs with 20 threads per inch (standard UNC coarse thread for that diameter). It will not take a 1/4-28 fine thread fastener.
2) Are these zinc plated steel nuts okay for outdoor or damp electrical work?
The HHN14V is zinc plated steel, which is a mild corrosion coating meant for dry indoor use, interior raceway, strut, and panel work. For wet locations, exterior runs, or coastal exposure, go to a hot dip galvanized or stainless 1/4-20 nut instead, since zinc plating will bloom and rust once it's wet repeatedly.
3) Is the Metallics HHN14V a regular hex nut or a heavy hex nut?
It's a heavy hex nut. Heavy pattern nuts have a larger width across the flats and a thicker body than a standard hex nut of the same 1/4-20 thread, so they need a bigger wrench and spread load over more bearing surface. If you're matching an existing standard hex nut on an assembly, the heavy version will look oversized next to it.
4) Will the HHN14V nut work with 1/4 inch all-thread rod for hanging conduit or strut?
Yes, as long as the rod is 1/4-20. Threaded rod in 1/4 inch is normally cut 20 TPI coarse, so these thread straight on for strut channel nuts, conduit hangers, trapeze supports, and rod-hung assemblies. Confirm the rod isn't metric M6, which looks close but will not engage.
5) How many nuts come in a box of Metallics HHN14V?
They ship 500 pieces to the box, which is a contractor or MRO bulk quantity rather than a small card pack. If you only need a handful for a service call, that's a lot of nut to carry; if you're standardizing a crib shelf or doing a full build-out with 1/4-20 strut and rod hardware, one box covers a job.
6) What is the Metallics part number for the 1/4-20 heavy hex zinc nut?
Order it as Metallics HHN14V. That one number covers the 1/4-20 heavy hex zinc plated steel nut in the 500 piece box.
