Metallics TPZBN1213 – Frequently Asked Questions
1) What thread size rod does the Metallics TPZBN1213 breakaway nut take?
The TPZBN1213 is a 1/2-13 nut, so it threads onto 1/2 inch all-thread rod with 13 threads per inch, the standard UNC coarse pitch used for 1/2 inch threaded rod hangers. It will not run on 1/2-20 fine thread.
2) What does a breakaway nut actually do on a threaded rod hanger?
A breakaway nut like the Metallics TPZBN1213 has a driving section that shears off once the nut is tightened to its set point, leaving the nut body seated on the rod. That gives a consistent installation without a torque wrench and a quick visual check that the connection was run up, which is why they show up on repetitive overhead rod work.
3) Is the Metallics TPZBN1213 nut plated for indoor electrical work?
It is steel with a zinc plating, which suits dry indoor runs like conduit, cable tray, strut and fixture hanging. Zinc plated steel is not a corrosion finish for wet, exterior or corrosive areas, so for those openings look at a stainless or hot dip galvanized fastener instead.
4) Can I use a breakaway nut instead of a standard hex nut on 1/2 inch all-thread?
Yes, on 1/2-13 rod the TPZBN1213 seats like a standard nut once the drive section shears. The difference is control: a plain hex nut is tightened by feel, the breakaway stops you at a fixed point. Where you need to back the connection off and re-tighten repeatedly, a standard 1/2-13 hex nut is the better choice, since the breakaway drive is single use.
5) How many nuts come in a box of Metallics TPZBN1213?
They ship 100 pieces to the box, so one box covers a sizable run of 1/2 inch rod drops without re-ordering mid-job.
6) Is this Metallics nut an electrical trade item or general construction hardware?
Metallics catalogs the TPZBN1213 as an electrical fastener, and it is sold that way for conduit, tray and fixture support on 1/2 inch rod. Nothing about the thread stops a mechanical or plumbing trade from using it on the same rod, but the product is stocked for electrical rough-in.
