Metallics RCT30 – Frequently Asked Questions
1) What thread size does the Metallics RCT30 rod coupling take?
The RCT30 coupling is threaded 5/8-11, so it mates with 5/8 inch all-thread rod in the standard UNC coarse pitch used for hanger rod. Both ends take the same thread, so it joins two lengths of 5/8-11 rod into one continuous run.
2) Will a 5/8-11 rod coupling work to extend threaded hanger rod on a conduit or pipe support run?
That is what it is for. The RCT30 splices two pieces of 5/8-11 threaded rod end to end, which is how you extend a drop that came up short without replacing the whole rod. Run each rod in far enough that it meets the other inside the coupling so the joint carries the load through full thread engagement, not just a few turns.
3) Is the Metallics RCT30 the same as a 1/2-13 rod coupling?
No. The RCT30 is 5/8-11 and will not accept 1/2 inch rod, which is cut 1/2-13. If the rod on your hangers measures 1/2 inch, you need the 1/2-13 coupling; 5/8 and 1/2 inch rod are the two sizes most often mixed up on a job because the couplings look similar in the bin.
4) Is the Metallics RCT30 coupling hex or round, and does that matter for installing it?
It is a hex body coupling. The flats let you hold or drive it with a standard wrench while you spin rod into it, which a round coupling nut does not allow. On overhead work that is the difference between snugging the joint in place and fighting it.
5) What is the finish on the RCT30 rod coupling, and is it suitable for damp indoor areas?
The RCT30 is zinc plated steel. Zinc plating handles normal indoor and damp-location service, such as mechanical rooms, parking structures and ceiling spaces. It is not a hot-dip galvanized or stainless part, so for direct outdoor exposure, coastal air or corrosive process areas you want a heavier corrosion-resistant coupling instead.
6) Can I use a 5/8-11 rod coupling as a load-bearing part of a hanger assembly, or is it just a splice?
It is a splice fitting for 5/8-11 threaded rod, and the joint is only as good as the thread engaged on each side. Thread both rods in so they butt near the center of the hex body. If you need a specified load rating for a seismic or engineered support, that value has to come from the engineer of record or a rated assembly; the coupling itself is sold as a 5/8-11 zinc plated steel rod coupling.
7) How many rod couplings come in a jar of Metallics RCT30?
The RCT30 is packed 25 pieces to a jar. That is a contractor-pack quantity, so it suits a trunk stock or a job where you are hanging multiple runs rather than making a single repair.
8) What part number do I order for the Metallics 5/8-11 hex rod coupling?
Order Metallics RCT30. That is the manufacturer part number for the 5/8-11 hex rod coupling in zinc plated steel, supplied in a 25 piece jar.
