Metallics JG5N165 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JG5N165 hex nut?
It's a 3/8-16 hex nut, meaning 3/8 inch nominal diameter with 16 threads per inch, which is the standard UNC coarse pitch for 3/8 inch. It will run onto any 3/8-16 coarse thread bolt, rod, or stud. If your rod is 3/8-24 fine thread, this is the wrong nut.
2) Is a Grade 5 nut strong enough to pair with my Grade 5 bolts and threaded rod?
Yes. The JG5N165 is a Grade 5 hardened steel nut at Rockwell C32 hardness, which is the matching nut grade for Grade 5 cap screws and bolts. Pairing a Grade 5 nut with a Grade 5 bolt lets you torque to the bolt's full rating without stripping the nut. Don't use it to replace a Grade 8 nut on a Grade 8 fastener.
3) Are Metallics JG5N165 hex nuts Buy American or ARRA compliant for a government job?
No. These nuts are not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing requirement, you'll need a domestically produced Grade 5 hex nut instead.
4) Can these zinc plated nuts be used outdoors or in a damp mechanical room?
Zinc plating over hardened steel gives these nuts moderate corrosion protection, which is fine for indoor electrical, plumbing, and HVAC work including unconditioned mechanical spaces. For direct weather exposure, wash-down areas, or coastal installs, a hot dip galvanized or stainless nut holds up longer.
5) How many nuts come in a jar and can I buy fewer than that?
The JG5N165 ships as a jar of 100 nuts, and 100 is the order minimum, so the jar is the smallest unit. Other sizes and quantities are available by request.
6) Will these hex nuts meet a spec calling out ANSI/ASME dimensional standards for fasteners?
The nuts are made to ANSI/ASME B182.2 dimensionally, with steel to AISI 1008-1026. That's the standard callout on most commercial fastener submittals, so the nut will interchange with any other B182.2 3/8-16 hex nut on the job.
7) How thick is the nut and will it clear a shallow strut channel or tight bracket?
Height on the 3/8-16 Grade 5 nut runs 0.320 to 0.337 inch, with a head height of 21/64 inch. That's the stack you need to account for when figuring thread engagement past the nut or clearance behind a plate.
8) How much does a jar of 100 3/8-16 Grade 5 nuts weigh for a shipment or a van stock list?
A full jar weighs 1.59 lbs and the container measures 3 inches long by 3 inches wide by 2.7 inches high, so it tucks into a tool bag or bin drawer easily for MRO stock.
