Metallics HHN38B – Frequently Asked Questions
1) What thread size is the Metallics HHN38B heavy hex nut?
The HHN38B is a 3/8-16 heavy hex nut in zinc-plated steel. It threads onto 3/8 inch rod or bolts cut to that same 16 threads per inch pitch, so confirm the rod you are using matches before you commit a full box.
2) Can I use these nuts with 3/8 inch threaded rod for hanging conduit and strut?
That is the usual application. The HHN38B is an electrical-trade 3/8-16 nut, so it mates with 3/8 inch all-thread rod of the same pitch used for trapeze hangers, strut channel, and conduit support. Pair it with the matching washers or channel nuts your hanger detail calls for.
3) How many nuts come in a box of Metallics HHN38B?
They ship 1500 pieces to the box. That is a bulk contractor pack, not a handful, so it suits a shop keeping 3/8 inch hardware on the shelf for conduit and strut work rather than a single repair.
4) Is a heavy hex nut different from a standard hex nut on 3/8 inch rod?
Yes, and it matters if you are matching existing hardware. A heavy hex nut like the HHN38B has a larger across-flats and a thicker body than a standard hex nut of the same 3/8-16 thread, so it needs a bigger wrench and bears on more surface. The thread fit is the same; the wrench size and footprint are not.
5) Is a zinc-plated steel nut OK for outdoor or damp electrical work?
Zinc plating on the HHN38B gives general corrosion resistance for dry indoor and protected locations. For sustained outdoor exposure, wet locations, or corrosive environments, step up to hot-dip galvanized or stainless 3/8-16 hardware instead.
