Metallics RCT30SS – Frequently Asked Questions
1) What thread size does the Metallics RCT30SS rod coupling take?
The RCT30SS is a 5/8-11 coupling, so it threads onto 5/8 inch all-thread rod with 11 threads per inch, which is the standard UNC pitch for 5/8 inch rod. Run the rod in from each end to join two lengths.
2) Is the Metallics RCT30SS rod coupling stainless steel or plated?
Stainless steel, not a plated carbon steel coupling. That matters when you are hanging trapeze, strut, or conduit racks in wet, damp, or corrosive areas, or outdoors where a zinc plated coupling would bloom rust. Pair it with stainless rod to avoid mixing metals.
3) Will a 5/8-11 coupling work on 1/2-13 or 3/8-16 threaded rod?
No. The RCT30SS only accepts 5/8-11 rod. Half inch rod is 1/2-13 and three eighths is 3/8-16, so neither will thread into it. Order the coupling that matches the rod diameter and pitch you are running.
4) Does the RCT30SS have a hex body I can get a wrench on?
It is a hex coupling, so you can hold or drive it with an open end or socket wrench while you run rod in from both sides. That is the practical difference from a round coupling nut, which you have to grip with pliers.
5) How many couplings come in a jar of Metallics RCT30SS?
They ship 50 to a jar. That is the sell unit, so order by the jar rather than by the piece when you are stocking a van or a job trailer for a hanger run.
6) Can I use a 5/8-11 rod coupling to extend hanger rod instead of buying longer rod?
Yes, that is what the RCT30SS is for. Joining two pieces of 5/8 inch all-thread with a coupling is the usual way to make up length in the field for conduit racks, trapeze hangers, and equipment supports. Thread the rod in far enough on each side that it meets near the middle of the coupling so both ends are fully engaged.
7) What is the exact Metallics part number for the 5/8-11 stainless hex rod coupling?
RCT30SS is the Metallics part number for the 5/8-11 stainless steel hex rod coupling supplied 50 per jar. Use that number when matching what is already on a job so you do not end up with a plated version in the same run.
