Metallics JTLN5 – Frequently Asked Questions
1) What thread size does the Metallics JTLN5 keps locknut take?
The JTLN5 is a 1/4-20 keps locknut, so it threads onto any 1/4 inch bolt or screw with 20 threads per inch (standard UNC coarse for that diameter). If your rod or screw is 1/4-28 fine thread, this nut will not run on.
2) Do I still need a separate lock washer with a keps nut?
No. The JTLN5 comes with an external tooth lock washer already attached to the nut, so it is one piece to pick up and one piece to run down. The washer OD measures 0.494 to 0.506 inch, which is what sits against your panel or strut surface.
3) Do Metallics JTLN5 nuts meet Buy American or ARRA requirements for a public job?
No. The JTLN5 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries domestic sourcing language, these will not qualify.
4) Are these zinc plated steel nuts okay for outdoor or damp locations?
The JTLN5 is steel with a zinc finish. Zinc plating handles indoor and normally dry conditions well, but it is not a stainless part, so for persistent wet, coastal, or washdown areas specify an 18-8 stainless locknut instead.
5) How are Metallics JTLN5 keps nuts packaged and what is the minimum order?
They ship in a jar of 100, and 100 is the order minimum (one jar). Jar weight is 0.72 lbs. Other sizes and quantities are available by request.
6) Is the JTLN5 locknut hard enough to bite into a painted or plated surface?
Rated Rockwell C38-44, so the external teeth are hard enough to dig into typical sheet steel, strut, and plated panel surfaces and resist backing off under vibration. Keep in mind the teeth mar the surface where they seat, so it is not the fastener for finished trim.
7) Is this an electrical fastener or can I use it for HVAC and plumbing work too?
Metallics lists the JTLN5 for electrical, plumbing, heating and air conditioning work, so it covers panel and enclosure assembly, strut and hanger hardware, and duct or equipment mounting with 1/4-20 hardware.
