Metallics HHN12V – Frequently Asked Questions
1) What thread size does the Metallics HHN12V heavy hex nut take?
The HHN12V is a 1/2-13 nut, meaning a 1/2 inch diameter with 13 threads per inch, which is the standard UNC coarse pitch for 1/2 inch rod and bolts. It will run onto 1/2-13 threaded rod, anchor bolts, and hex bolts; it will not fit 1/2-20 fine thread.
2) Is a heavy hex nut different from a standard hex nut on 1/2 inch rod?
Yes. The HHN12V is a heavy hex pattern, so the nut body is wider across the flats and thicker than a finished hex nut of the same 1/2-13 thread. That gives more bearing area against a plate or channel and takes a larger wrench size. Thread fit is identical, so it threads onto the same 1/2-13 rod, but check wrench clearance in tight pipe-hanger or strut assemblies before standardizing on heavy hex.
3) Are these Metallics 1/2-13 nuts plated for corrosion resistance?
They are steel with a zinc plating. That suits dry indoor electrical and mechanical work, interior hanger rod, strut, and equipment mounting. For wet exterior, coastal, or corrosive locations, zinc-plated steel is not the right choice, go to hot-dip galvanized or stainless.
4) How many nuts come in a box of Metallics HHN12V?
500 pieces per box. That is a bulk contractor or MRO quantity, sized for crews hanging 1/2 inch rod across a whole job or for restocking a shop bin, rather than a single-fixture count.
5) What is the Metallics part number to order for a 1/2-13 heavy hex zinc nut?
Order Metallics HHN12V. That part number covers the 1/2-13 heavy hex steel nut with zinc plating in the 500 piece box.
