Metallics JNM04 – Frequently Asked Questions
1) What thread does the Metallics JNM04 hex nut take, M4 coarse or fine?
The JNM04 is an M4 nut with a 0.7 mm thread pitch, which is the standard M4 coarse thread. It will run onto any M4-0.7 screw, bolt or threaded rod. There is no fine-pitch version in the JNM04 designation.
2) Is the Metallics JNM04 nut made to DIN 934?
Yes, the M4 hex nut is built to DIN 934, the common metric hex nut standard. That matters if you are matching nuts already on a piece of imported equipment or gear tray, because DIN 934 fixes the across-flats and height dimensions so the same wrench and the same stack height carry over.
3) Do the Metallics JNM04 nuts meet Buy American or ARRA requirements?
No. The M4 zinc plated hex nut is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If you are on a federally funded job with domestic sourcing language in the spec, these will not satisfy it.
4) Are these zinc plated steel nuts okay for outdoor or wet locations?
The JNM04 is zinc plated steel, which is a dry-location and light-duty finish. It handles indoor panel work, strut, and conduit support fine, but in wet, washdown, or coastal exposure the plating will eventually give up. For those runs step up to a stainless nut instead of the steel-zinc.
5) How many M4 nuts come in a jar of Metallics JNM04?
They ship as a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest quantity. The jar packaging is what makes these practical on a service van, you can pour out a handful without chasing loose nuts around a bag.
6) How hard are these M4 nuts, and will they strip on a torqued joint?
Hardness runs Vickers HV 150 to 302, roughly Rockwell B78.7 to C30. That is standard commercial hex nut hardness, enough for normal assembly torque on general electrical and mechanical work. It is not a structural or high-strength nut, so do not substitute it where a drawing calls out a specific property class.
7) What trades use the Metallics JNM series metric hex nuts?
These are stocked for electrical, plumbing, and HVAC work, panel and enclosure hardware, equipment mounting, hanger and support assembly. The M4 size is common on imported gear where the machine screws are metric rather than #8 or #10.
8) Can I get the JNM metric nuts in a size other than M4 or in a larger quantity?
Yes. The JNM04 covers M4 in a 100-piece jar, and other sizes and quantities in the series are available by request. If you are standardizing a facility on metric fasteners, ask for the size range rather than ordering jar by jar.
9) How much does a jar of 100 M4 hex nuts weigh for shipping?
The jar comes in at 2.05 lbs, with jar dimensions of 3 x 3 x 2.15 inches. Small enough to keep several sizes in a single drawer of a van bin system.
