Metallics JTLN4 – Frequently Asked Questions

1) Will a 10-32 Keps lock nut thread onto a standard #10-32 machine screw used for electrical box and panel mounting?
Yes. The Metallics JTLN4 is cut 10-32, meaning 32 threads per inch on a #10 screw, so it mates with the #10-32 machine screws and ground screws standard in panels, enclosures and device mounting. Thread engagement is normal right-hand UNF; the washer does the locking, not an interference thread.
2) Do I still need a separate star washer with these Keps nuts?
No. The external tooth lock washer is captured on the nut face, so one piece does the job of a hex nut plus a free star washer. That means one hand holding one part on a panel install instead of two, and no loose washers dropped into an enclosure. Washer outside diameter is 0.395 to 0.406 in., so it bears on the sheet metal rather than falling into an oversized hole.
3) Can I use Metallics JTLN4 lock nuts on a federally funded or Buy American job?
No. The JTLN4 is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. If your contract carries a domestic sourcing clause, specify a domestically produced fastener instead.
4) What size wrench or socket fits a Metallics JTLN4 Keps nut?
Across the hex flats the nut measures 0.362 to 0.375 in., so a 3/8 inch wrench, socket or nut driver is the fit. Overall width across the washer teeth runs 0.413 to 0.433 in., so a deep socket seats over the hex without binding on the washer.
5) How much clearance do I need behind the panel for these lock nuts?
Stack height of the nut is 0.117 to 0.130 in., so budget about an eighth of an inch of depth past the end of the screw plus whatever thread stick-out you have. That makes them workable in tight enclosure corners and on raceway brackets where a jam nut and separate washer would not fit.
6) Will zinc plated steel Keps nuts hold up in a damp mechanical room or outdoor enclosure?
The JTLN4 is steel with a zinc plated finish, which handles indoor and normally dry or damp conditions. For wet, washdown, coastal or chemically aggressive locations, step up to 18-8 stainless Keps nuts instead; zinc plating is a sacrificial coating and will eventually corrode once it is breached.
7) Will these vibration-proof nuts stay tight on HVAC equipment and machinery mounts?
That is what the external tooth washer is for. The teeth dig into the clamped surface and resist back-off under vibration, which is why Metallics lists the JTLN series for electrical, plumbing, and heating and air conditioning work. On soft or painted surfaces the teeth will mar the finish, so put them on a bare metal bearing face where appearance does not matter.
8) Keps nut versus nylon insert lock nut for 10-32 electrical work, which should I use?
A Keps nut like the JTLN4 locks mechanically with external teeth that bite the mating metal, so it works at any temperature and installs as one piece with a 3/8 inch driver. A nylon insert nut locks on the thread instead, does not mar the surface, and is better where you are clamping painted or plated sheet you want to keep intact or where there is no solid bearing face for teeth to grab. For grounded metal enclosures and bare steel brackets, the toothed Keps is the usual pick because the teeth also cut through coating to help continuity.
9) Are these lock nuts hard enough to reuse, or are they one-time use?
Hardness is specified Rockwell C38-44. The locking action comes from the external teeth biting the mating surface rather than from a deformed nylon insert, so the nut body is not sacrificed on removal. The teeth do flatten with repeated cycles, so for anything you expect to service often, plan on fresh nuts at reassembly.
10) How are these Metallics 10-32 Keps nuts packaged, and what is the minimum I can buy?
They come in a jar of 100 pieces, and the jar is the order unit with a 100 piece minimum. Total packed weight is 0.4 lbs, so a jar sits easily in a service van bin or on a shop shelf.
