Metallics TRS812 – Frequently Asked Questions
1) What thread size and length is the Metallics TRS812 threaded rod?
The TRS812 is 3/8-16 threaded rod in 12 foot lengths, steel with a zinc finish. The 3/8-16 call-out means a 3/8 inch diameter with 16 threads per inch, which is the standard UNC coarse thread that pairs with off-the-shelf 3/8-16 nuts, couplings, and strut hardware.
2) Does the Metallics TRS812 come as a single rod or a bundle?
It ships as a bundle of 12 rods, not a single stick. Order quantity one and you are getting 12 pieces of 12 foot rod, so plan the buy around 144 linear feet rather than per-rod.
3) Can 3/8-16 zinc threaded rod be used for hanging electrical conduit and strut?
Yes, that is the normal use for it. The TRS812 is sold as electrical trade stock, and 3/8-16 is the standard hanger rod size for strut channel, trapeze hangers, conduit clamps, and beam clamps. Cut it to length on site with a bandsaw or portable band and chase the cut end with a 3/8-16 die so nuts start clean.
4) Is zinc plated threaded rod okay outdoors or in a wet area?
The TRS812 is zinc plated steel, which is a mild corrosion coating meant for dry interior work. For exterior, wash-down, pool, or coastal jobs, zinc plating will bloom and rust at the cut ends. Specify hot dip galvanized or 304/316 stainless rod in those locations instead.
5) What nuts and washers do I need with Metallics TRS812 rod?
The bundle is bare rod only, no nuts, washers, or couplings included. You will need 3/8-16 hex nuts and flat washers at every connection point, plus 3/8-16 rod couplings if you are splicing lengths and a 3/8 inch beam clamp, concrete anchor, or strut nut at the structure end.
6) How do I order Metallics threaded rod, and what is the part number?
Order by manufacturer part number TRS812 from Metallics. One model covers it, there are no finish or length options to pick, so the only decision is how many 12-piece bundles you need.
