Metallics JTLN4SS – Frequently Asked Questions
1) Are these locknuts stainless, and will they hold up outdoors or in a wet location?
They are 18-8 stainless steel, the standard 300 series austenitic grade, so they resist rust in damp and outdoor enclosures far better than zinc plated steel. The free spinning washer is captive to the nut, so there is no loose washer to drop in a panel. Hardness is Rockwell C40-50.
2) What wrench or socket size do I need for these 10-32 keps nuts?
Use a 7/16 inch wrench or socket. The nut's across-flats width runs 0.413 to 0.433 inch and the spec notes that the width dimension is the wrench size, so a 7/16 (0.4375) opening is the fit. The washer flange sits outside that at 0.395 to 0.406 inch OD, so a deep socket or open wrench seats on the hex without fouling the washer.
3) How much clearance do I need behind the panel for a keps locknut versus a nut plus separate washer?
Height of the JTLN4SS runs 0.117 to 0.130 inch, with a hex head width of 0.362 to 0.375 inch. That stack is one piece: the toothed washer is already attached, so you are not adding a separate washer thickness behind the panel. In tight device boxes and enclosure knockouts, that keeps the fastener profile low and cuts the handling to one part instead of two.
4) Will a keps nut chew up the threads on my screw the way a nylon or distorted thread locknut can?
No. The locking action is in the free spinning toothed washer, which bites the work surface rather than the screw thread, so it does not gall the screw thread. That is why it is the most common locknut type for repetitive assembly work, and why a screw can usually be backed out and reused.
5) Do these Metallics locknuts meet Buy American or ARRA requirements for a federal or public project?
The JTLN4SS is flagged both Buy American compliant and ARRA compliant in the product record. Country of origin is listed as multiple, so if your specification requires a single named origin on the submittal, that is the detail to pin down for the lot you receive.
6) Are the dimensions on these keps nuts to a standard, so they interchange with what is already in my panel?
Yes, they are made to American Standard dimensions, and the thread is 10-32 UNF right hand. Any 10-32 screw or stud already in the enclosure takes this nut, and the hex will match the 7/16 wrench your other American standard 10-32 hardware uses.
7) How do these 10-32 keps locknuts come packaged, and what is the minimum order?
They ship in a jar of 100, and 100 count is the order minimum. That is a shop or truck stock quantity rather than a bulk box, which suits an MRO crib or a service van where you want one container of 10-32 locknuts on the shelf. Jar weight is 0.41 lbs.
8) I need the same keps locknut in a different size or a larger quantity. Is that available?
The JTLN series covers other sizes and pack quantities beyond this 10-32 stainless jar of 100, available by request. If you are standardizing a facility on one locknut type, specify the thread size you need and the count you want per container.
