Metallics JNC166 – Frequently Asked Questions
1) What thread size is the Metallics JNC166 copper hex nut?
The JNC166 is a 1/2-13 hex nut, meaning a 1/2 inch diameter with 13 threads per inch, which is the standard UNC coarse thread for that diameter. It mates with any 1/2-13 threaded rod, bolt, or ground rod clamp stud.
2) Is the JNC166 nut solid copper, and why would I use copper instead of steel?
Copper is the material on the JNC166 hex nut. Electricians specify copper nuts on grounding and bonding work so the nut matches the copper conductor or copper-bonded rod it sits against, which avoids dissimilar metal corrosion at the connection. For general structural fastening a plated steel nut is the usual choice.
3) Will the JNC166 copper nut thread onto 1/2 inch copper-bonded ground rod hardware?
Yes, as long as the mating thread is 1/2-13. That is the thread on the JNC166, so it runs onto any 1/2-13 male thread, including threaded rod and clamp studs cut to that spec. It will not fit 1/2-20 fine thread.
4) How many nuts come in a jar of Metallics JNC166?
100 nuts per jar. The jar pack is how it ships, so ordering one gets you the full hundred rather than a loose count, which suits a service van or a shop bin for grounding work.
5) Is there more than one size or model offered under Metallics JNC166?
JNC166 is a single model, the 1/2-13 copper hex nut in a 100 count jar. There is no size or finish choice to make when ordering it; if you need a different diameter you need a different Metallics part number.
6) Do I need a washer with the JNC166 copper hex nut?
The jar contains hex nuts only, no washers or bolts. On grounding connections where the nut bears on a lug or plate, order copper or bronze flat washers separately to spread the load and keep the metals consistent through the joint.
