Metallics JHLN38C – Frequently Asked Questions
1) What thread size is the Metallics JHLN38C locknut, and what bolt does it fit?
The JHLN38C is a 3/8-16 hex locknut, so it threads onto 3/8 inch rod or bolt cut to that pitch. Match the thread callout on your rod exactly before ordering; a 3/8-16 nut will not run onto 3/8-16 UNC's more common 3/8-16 sibling pitches used on other hardware.
2) Is the Metallics JHLN38C an all-metal locknut or does it have a nylon insert?
All metal. The JHLN38C uses a deformed metal thread to create prevailing torque rather than a nylon insert, which is what you want where heat would soften or destroy a nylon ring, such as near lighting ballasts, motors, or any hot electrical enclosure.
3) How many 3/8-16 locknuts come in a jar of Metallics JHLN38C?
One hundred nuts per jar. The jar pack is the standard buying unit on the JHLN38C, which suits an electrical contractor stocking a van or a truck for threaded rod work rather than someone needing a handful.
4) Will a 3/8-16 all-metal locknut work for hanging strut and threaded rod in an electrical install?
Yes, for 3/8 inch rod and strut channel nuts cut to 3/8-16, the JHLN38C is the locking nut that keeps the connection from backing off under vibration. It is an electrical-supply fastener, so it is the nut used on fixture hangers, conduit trapeze supports, and strut assemblies. It is a nut only, so order your rod, strut, washers, and channel hardware separately.
5) Can I reuse an all-metal hex locknut like the JHLN38C after taking it off?
All-metal prevailing-torque locknuts hold by deformed thread, and the locking force drops each time the nut is run on and off. For a maintenance crew pulling fixtures down repeatedly, plan on replacing the nut rather than reusing it, which is part of why the JHLN38C is sold in a 100-count jar.
