Metallics JN165D – Frequently Asked Questions
1) Will the JN165D nut thread onto 3/8 inch all-thread rod used for conduit and strut hangers?
Yes, provided the rod is 3/8-16 UNC right-hand thread, which is the standard coarse thread on electrical hanger rod. The JN165D is cut 16 threads per inch, UNC, right hand, to ASME B18.2.2, so it runs on 3/8-16 rod, strut hardware, and 3/8-16 bolts. It will not fit 3/8-24 fine thread.
2) Is a Grade 2 hex nut strong enough for the bolts I am using, or do I need Grade 5?
Grade 2 nuts like the JN165D are matched to low carbon bolts and screws that are not heat treated, with a specified minimum tensile strength of 74,000 psi or less. Hardness runs Rockwell B68 to C32. If you are torquing a heat treated Grade 5 or Grade 8 bolt, step up to a matching Grade 5 or Grade 8 nut instead, otherwise the nut becomes the weak point in the joint.
3) How many nuts come in a jar of Metallics JN165D, and is there a minimum order?
The JN165D ships as a jar of 100 nuts, and 100 count is the order minimum, so one jar is the smallest buy. Jar packaging keeps them from spilling in a gang box or on a cart better than a poly bag.
4) Can I use these zinc plated steel nuts outdoors or in a damp location?
The JN165D is zinc plated steel, silver in appearance. Zinc plating handles dry indoor work and incidental moisture, but it is a sacrificial coating, not stainless. For wet locations, washdown areas, or coastal exposure, specify a hot dip galvanized or 18-8 / 316 stainless 3/8-16 hex nut instead.
5) Do these hex nuts meet Buy American and ARRA requirements for a federal or institutional job?
Metallics flags the JN165D as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, so if your specification demands a single documented origin, request the mill paperwork for the lot you receive.
6) What is the shipping weight of a 100 count jar of JN165D nuts?
A jar of 100 of the 3/8-16 zinc plated hex nuts weighs 1.58 lbs. Useful if you are building out a stock order of several sizes and watching box weight.
7) I need 1/2-13 or 1/4-20 hex nuts in the same zinc finish. Does the JN series cover other sizes?
The JN165D is the 3/8-16 size in the Metallics JN hex nut series, and Metallics states other sizes and quantities are available by request. Same Grade 2 zinc plated steel construction across the line, so you can standardize one finish across a facility's fastener bins.
