Metallics HHN38M – Frequently Asked Questions
1) What thread size are the Metallics HHN38M heavy hex nuts?
The HHN38M is a 3/8-16 heavy hex nut in zinc plated steel. Match the thread to your rod or bolt before ordering, since 3/8 rod is also commonly threaded 3/8-16 in strut and hanger work.
2) Can I use the Metallics HHN38M nut on 3/8 inch threaded rod for conduit and pipe hangers?
Yes, as long as the rod is 3/8-16 thread. That is the common coarse thread for 3/8 inch hanger rod, and the HHN38M is a steel zinc 3/8-16 heavy hex nut, so it runs on continuously threaded rod, strut hardware, and beam clamps using that thread.
3) How many nuts come in a box of Metallics HHN38M?
They ship 1000 pieces per box, which is why this one is bought by electrical contractors and MRO stockrooms standardizing on 3/8-16 hardware rather than for a single repair.
4) Are zinc plated heavy hex nuts like the HHN38M suitable for outdoor or wet locations?
Zinc plating gives moderate corrosion resistance and is intended for dry indoor use, which covers most interior conduit, strut and hanger rod work. For exterior, damp, or corrosive environments, specify a hot dip galvanized or stainless 3/8-16 nut instead.
5) What is the difference between a heavy hex nut and a standard hex nut in 3/8-16?
A heavy hex nut has a larger across-flats width and greater thickness than a finished hex nut of the same thread, so it spreads load over a wider bearing area and takes a bigger wrench. The HHN38M is the heavy pattern in 3/8-16, so if your drawing or existing assembly calls out a standard finished hex nut, the wrench size and clearance will differ.
