Metallics RCT27SS – Frequently Asked Questions
1) What thread size does the Metallics RCT27SS rod coupling take?
The RCT27SS rod coupling is threaded 5/16-18, so it joins two lengths of 5/16-18 threaded rod (the common coarse thread for 5/16 inch rod). Both ends share that same thread, so it is a straight coupling, not a reducer.
2) Is the Metallics RCT27SS coupling stainless steel or plated?
Stainless steel, not a plated carbon part. That is what the SS in RCT27SS refers to, and it is the reason to pick this one for damp, washdown, or exterior hanger runs where zinc plating would rust at the thread.
3) Can I use a 5/16-18 stainless rod coupling to extend hanger rod for conduit and strut?
Yes, that is the job it does. The RCT27SS is a 5/16-18 stainless hex coupling that splices two pieces of 5/16-18 threaded rod end to end, which is how you lengthen a drop for conduit hangers, strut trapezes, or fixture support without buying a longer rod. Thread both rods in far enough that they meet near the middle of the coupling so the splice carries load through full thread engagement.
4) Will the RCT27SS work with 3/8-16 threaded rod?
No. It is cut 5/16-18 only, so 3/8 inch rod will not enter it and 1/4-20 rod will spin loose inside it. For a 3/8 inch drop you need a 3/8-16 coupling instead.
5) Is the RCT27SS rod coupling hex or round bodied?
Hex bodied. The flats let you hold the coupling with a wrench while you spin rod into it, which matters when you are extending trapeze or conduit hanger rod overhead and cannot get a grip on a round sleeve.
6) How many rod couplings come in a jar of Metallics RCT27SS?
They ship 50 to a jar. That is a bulk electrical-fittings pack meant for stocking a van or a job trailer, so expect the full jar quantity rather than individual pieces.
