Metallics RCT29SS316 – Frequently Asked Questions
1) What thread size does the Metallics RCT29SS316 rod coupling take?
It takes 1/2-13 threaded rod, so both ends accept standard 1/2 inch coarse (13 threads per inch) all-thread. If the rod on your hanger run is 3/8-16 or 5/8-11, this coupling will not thread on and you need the matching size instead.
2) Is this Metallics rod coupling stainless steel, and can it be used outdoors or in a wet area?
The RCT29SS316 is a stainless steel coupling, which is what electrical and mechanical contractors reach for when a hanger run is outdoors, in a parking garage, in a wash-down area, or anywhere a plated carbon steel coupling would rust at the joint. Pair it with stainless threaded rod so you are not mixing metals at the splice.
3) How many rod couplings come in a jar of the Metallics RCT29SS316?
They ship 50 to a jar. That is a bulk pack sized for a job where you are extending a whole run of hanger rod, not a single splice, so MRO and institutional buyers stocking a shop crib usually land on this rather than onesies.
4) What is a threaded rod coupling actually used for on an electrical job?
It joins two lengths of threaded rod end to end. On conduit racks, strut trapeze hangers, light fixture drops and equipment supports, stock rod comes in fixed lengths, so when the drop from the deck is longer than one stick you thread a coupling onto the first rod and run the second into the other end. The 1/2-13 size here is the common heavier hanger rod used for trapeze and larger conduit racks.
5) Will this coupling work on 1/2 inch rod that has a fine thread?
No. The RCT29SS316 is cut 1/2-13, which is the coarse UNC pitch. A 1/2-20 fine-thread rod has the same outside diameter but will not run into it, and forcing it will gall the threads, especially in stainless. Match the pitch, not just the diameter.
6) Why does this rod coupling have a hex body instead of a round one?
The hex shape gives you a wrench flat. When you are splicing threaded rod overhead and the rod wants to spin with you, you can hold or drive the coupling with a standard wrench rather than fighting it by hand, which is the practical reason hex couplings get specified on long hanger drops.
7) Is the part number for ordering this Metallics coupling RCT29SS316?
Yes, RCT29SS316 is the Metallics manufacturer part number, and it covers the 1/2-13 hex stainless coupling supplied 50 per jar. That is the number to put on a distributor purchase order.
