Metallics JG5N165D – Frequently Asked Questions
1) What size bolt does the Metallics JG5N165D hex nut thread onto?
It's a 3/8-16 nut, so it threads onto 3/8 inch bolts and rod with 16 threads per inch, UNC coarse thread, right hand. That's the standard coarse pitch for 3/8 inch hardware, so it mates with ordinary 3/8-16 all-thread, strut hardware, and hex bolts. It will not run on 3/8-24 fine thread.
2) Is a Grade 5 hex nut strong enough for threaded rod hanging pipe and conduit?
Grade 5 is a medium carbon hardened steel nut at Rockwell C32, made from AISI 1008-1026 steel. The rule to follow is simple: use it with bolts or rod whose tensile strength is equal to or less than the nut's specified proof stress. Pair it with Grade 5 bolts or rod and the joint is matched. If your drawing calls for Grade 8 fasteners, step up to a Grade 8 nut instead so the nut is not the weak link.
3) Will these nuts fit standard American hex prep and match the nuts already on my job?
They're built to ANSI/ASME B182.2 dimensions, so they interchange with any other 3/8-16 hex nut made to the same American standard. Head width runs 0.551 to 0.562 inch and head height 21/64 inch. If your existing hardware is metric or a non-standard hex, it won't match.
4) Can these zinc plated hex nuts be used outdoors or in damp areas?
The finish is zinc plating over hardened steel, silver in appearance. Zinc gives corrosion resistance for indoor and sheltered work, which is what most electrical and MRO fastening is. For sustained wet exposure, direct weather, or corrosive environments, specify a hot dip galvanized or stainless 18-8 nut instead.
5) Do these Metallics hex nuts qualify for Buy American or ARRA funded projects?
The JG5N165D is flagged both ARRA compliant and Buy American compliant, which is what a government, school, or healthcare procurement spec usually asks for on fasteners. Country of origin is listed as multiple.
6) How are the JG5N165D hex nuts packaged and what is the minimum I can order?
They ship 100 nuts in a jar, and 100 count is the order minimum. The jar weighs 1.56 lbs. The jar format is handy for a service truck or a shop bin rather than loose bulk.
7) I need 1/2-13 or a different quantity of Grade 5 hex nuts. Can I get them in the same series?
Yes. The JG5N series Grade 5 zinc hex nuts are offered in other sizes and other pack quantities by request, so if the 3/8-16 in a 100 count jar isn't the size or count you need, the equivalent can be sourced in the same series and finish.
