Metallics JTLN2 – Frequently Asked Questions
1) Will an 8-32 keps nut thread onto a standard 8-32 machine screw used in electrical panels?
Yes. The Metallics JTLN2 is a #8 nut cut at 32 threads per inch, which is the standard 8-32 machine screw thread used for device mounting, panel hardware, and ground screws. Anything stamped or spec'd 8-32 will take it.
2) Do I need a separate lock washer with a keps nut?
No. The keps nut carries its own external tooth washer, captive on the nut, so you drive one piece instead of stacking a nut and a washer. The teeth bite the mating surface and resist back-off under vibration, which is why these get used on panel and HVAC equipment assembly.
3) Do these Metallics keps nuts meet Buy American or ARRA requirements on a federal job?
No. The JTLN2 keps nuts are not Buy American compliant and are not ARRA compliant, and country of origin is listed as multiple. On a federally funded project with domestic sourcing requirements, these will not qualify.
4) Are zinc-plated steel keps nuts suitable for outdoor or damp locations?
Steel with a zinc plating is a general-purpose corrosion finish, fine for indoor panels, machinery, and conditioned spaces. For wet, washdown, coastal, or chemically aggressive locations, stainless (18-8) keps nuts are the better call, since zinc plating is a sacrificial coating rather than a corrosion-resistant base metal.
5) How many 8-32 keps nuts come in a jar and can I buy less than a full jar?
They ship in a jar of 100 pieces, and the jar is the order minimum, so 100 is the smallest quantity. The jar weighs 0.33 lbs and keeps the nuts contained on a truck or in a service van bin.
6) Keps nut versus nylon insert lock nut for 8-32 hardware, which should I use?
A keps nut like the JTLN2 locks by biting the surface it clamps, so it works best on sheet metal and painted or bare panels where you want an electrical path through the joint and a one-piece install. A nylon insert nut locks on the thread itself, holds better when there is no firm bearing surface to bite, and is the choice where you need to remove and reinstall the nut. Keps are also the faster of the two on production assembly since there is no separate washer to handle.
7) What does the Rockwell C38-44 hardness mean for how tight I can run these?
C38-44 is a hardened nut, which is what keeps the washer teeth from flattening out and lets the threads take torque without stripping or galling. Practically, it means the nut is harder than the sheet metal it clamps, so the teeth embed into the panel rather than deform.
8) Can a keps nut be reused after I take it apart?
Treat it as single-use for locking purposes. The teeth on the external washer deform the mating surface and themselves on first tightening, so a backed-off and re-run nut will not hold the same. For maintenance work where the same joint gets opened repeatedly, pull a fresh nut from the jar each time, which is part of why these come 100 to a jar.
