Metallics JTLN5SS – Frequently Asked Questions

1) Will a 1/4-20 keps lock nut thread onto 1/4-20 bolts and threaded rod?
Yes. The Metallics JTLN5SS is a 1/4-20 nut, 20 threads per inch, so it runs on any standard 1/4-20 UNC bolt, machine screw, or threaded rod. That is the common coarse thread for 1/4 inch fasteners, so it will not mate with 1/4-28 fine thread.
2) Do I still need a separate lock washer with these keps nuts?
No. The external tooth lock washer is already attached to the nut, so you drive one piece instead of staging a washer and a nut. The washer outside diameter runs 0.494 to 0.506 inch, which is what bears on the panel or bracket surface, so make sure your mounting hole and any slot are small enough for that to seat.
3) Can I use these on a federally funded job with domestic preference requirements?
No. The Metallics JTLN5SS keps nuts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. For a job carrying domestic sourcing requirements you need a fastener certified as domestic.
4) What wrench or socket size do these 1/4-20 hex keps nuts take?
Across the flats the hex measures 0.423 to 0.438 inch, so a 7/16 inch socket or wrench fits. Overall width including the washer teeth is 0.482 to 0.505 inch, and nut height is 0.178 to 0.193 inch, which matters if you are working in a tight enclosure.
5) Will stainless keps nuts hold up outdoors or in a damp mechanical room?
They are 18-8 stainless steel, which is the austenitic grade used where plated steel would rust, so they suit damp mechanical rooms, exterior conduit runs, and rooftop equipment. Pair them with stainless bolts where you can to avoid mixing metals at the joint.
6) Will these keps nuts stay tight on vibrating HVAC equipment?
The serrated external teeth bite into the mating surface as the nut is tightened, which is what resists back-off under vibration, and the nut is heat treated to Rockwell C40-50 so the teeth do not flatten out under load. That makes them a reasonable choice for air handler panels, blower assemblies, and equipment mounts.
7) How many 1/4-20 keps nuts come in a jar, and can I buy fewer?
They ship as a jar of 100 pieces, and 100 is the order minimum, so the jar is the smallest unit. The full jar weighs 0.73 lbs.
8) Are keps nuts suitable for grounding or electrical bonding connections?
The serrated teeth are designed to bite the mating surface, and these nuts are catalogued for electrical, plumbing, and heating and air conditioning work, which covers panel and enclosure hardware. For a listed bonding or grounding connection, though, use the grounding hardware specified for that equipment rather than a general purpose keps nut.
