Metallics RCT28G – Frequently Asked Questions
1) What thread size does the Metallics RCT28G rod coupling take?
The RCT28G coupling is threaded 3/8-16, so it joins standard 3/8 inch threaded rod with 16 threads per inch. Run both rod ends in from either side to make up the splice. If your rod is 1/2-13 or 1/4-20, this is the wrong coupling.
2) Is this rod coupling galvanized for damp or outdoor hanger runs?
Galvanized finish, yes. That makes the RCT28G suitable for damp interior locations and the kind of exposure you get in parking structures, mechanical rooms, and unconditioned space, rather than plain steel. For fully corrosive or wash-down environments, stainless rod hardware is the better call.
3) How many rod couplings come in a jar of Metallics RCT28G?
It ships as a jar of 50 couplings. That is the pack quantity, so a single order covers a full hanger run of conduit or pipe trapeze supports without reordering mid-job.
4) What is a hex rod coupling used for on a conduit or pipe hanger job?
It is a hex-bodied nut, longer than a standard nut, used to splice two lengths of threaded rod end to end. Electricians and pipefitters use them to extend a drop from the deck when a single stick of rod will not reach, or to join rod to a threaded insert or hanger stud. The RCT28G is the 3/8-16 galvanized version. The hex body lets you drive it with a wrench while the rod ends are run in.
5) Can I use the RCT28G coupling to join 3/8 inch rod to a threaded ceiling insert?
Yes, provided the insert or stud is also 3/8-16. The coupling is threaded through for 3/8-16 on both ends, so anything with that same thread, rod, hanger stud, or eye bolt shank, will thread into it.
