Metallics JTLN6SS – Frequently Asked Questions

1) What thread does the Metallics JTLN6SS keps locknut take?
It's a 5/16-18 nut: UNC coarse thread, 18 threads per inch, right-hand. It threads onto any 5/16-18 UNC bolt or machine screw running right-hand.
2) Is the JTLN6SS locknut stainless, and will it hold up outdoors or in a damp mechanical room?
The nut is 18-8 stainless steel, which is the austenitic grade normally specified for wet interior and general exterior service. Hardness runs Rockwell C40-50.
3) Do I still need a separate washer with a keps locknut?
No. A keps nut carries a free-spinning toothed washer captive on the nut, so the washer and the locking action come as one piece. The washer OD on the JTLN6SS measures 0.579 to 0.592 inch, and overall nut height is 0.258 to 0.273 inch, so plan for that much stack under the fastener. If you need broader bearing area on sheet metal or a slotted strut, add a flat washer under the nut.
4) Does the Metallics JTLN6SS locknut meet Buy American and ARRA requirements for a federal or institutional job?
Metallics lists the JTLN6SS as compliant for both ARRA and Buy American. Country of origin is recorded as multiple, so if your specification requires a single named origin on the submittal, confirm the origin on the lot you receive.
5) Will a keps locknut chew up the bolt threads like an all-metal lock nut can?
No. The locking is done by the captive toothed washer biting the work surface, not by distorted threads, so it doesn't gall the screw thread. That's also why it's the most common locknut choice: low cost and it spins on with a plain socket, no prevailing-torque drag. For repeated removal and reinstallation on the same fastener, a nylon-insert nut is the usual alternative.
6) How many 5/16-18 stainless keps nuts come in a jar of the Metallics JTLN6SS?
100 pieces, packed in a jar, and 100 count is also the order minimum. The jar weighs 1.18 lbs.
7) Can I get this keps locknut in other thread sizes or a different pack quantity?
The JTLN series covers other sizes and quantities by request beyond the 5/16-18 stainless jar of 100. If you're standardizing a facility on one locknut type across several bolt diameters, ask for the sizes you need rather than mixing nut styles.
