Metallics TRS7/3 – Frequently Asked Questions
1) What thread size and length is the Metallics TRS7/3 threaded rod?
The TRS7/3 is a 5/16-18 threaded rod cut to 3 feet. The 5/16-18 callout means a 5/16 inch diameter with 18 threads per inch, which is the standard UNC coarse pitch for that diameter, so it takes common 5/16-18 hex nuts and couplings.
2) Is this threaded rod galvanized or plain steel?
Steel with a zinc finish, which is what the "St-zn" in the TRS7/3 description stands for. Zinc plating gives mild corrosion resistance for dry interior work such as hanging conduit, strut, cable tray and light fixtures. For wet, exterior or corrosive locations, step up to a hot-dip galvanized or stainless rod instead.
3) Can I cut this 3 foot threaded rod down to length on the job?
Yes. Fully threaded rod is cut to length with a bandsaw, portaband or bolt cutter and the end chased with a nut or file so the threads start clean. The TRS7/3 is a 3 foot length, so one piece yields several shorter drops for conduit or fixture hanging.
4) Does the Metallics TRS7/3 come with nuts and washers?
No. The TRS7/3 is rod only, 5/16-18 by 3 feet in zinc-plated steel. Order your 5/16-18 hex nuts, flat washers, channel nuts, beam clamps or rod couplings separately to complete the hanger assembly.
5) How is this threaded rod packaged, as a single piece or a bundle?
The TRS7/3 is sold by the piece, and the pack type is a bundle, so quantities ship bundled together rather than individually wrapped. That is normal for 3 foot rod going out to a job site.
