Metallics MSNRCN1213 – Frequently Asked Questions
1) What thread size does the Metallics MSNRCN1213 spring cone nut take?
It is a 1/2-13 nut, meaning 1/2 inch nominal diameter at 13 threads per inch, cut to ANSI/ASME B1.1. That is the standard UNC coarse pitch for 1/2 inch rod, so it threads onto standard 1/2-13 all-thread or hanger rod without an adapter.
2) Do these spring cone nuts meet Buy American and ARRA requirements for a federal or public job?
Both are flagged compliant on the MSNRCN1213: Buy American compliant and ARRA compliant. Country of origin is listed as multiple, so if your contract requires a single named country of manufacture on the submittal, confirm the origin of the specific lot you receive.
3) Is a spring cone nut the right part for hanging threaded rod, or should I use a standard hex nut?
A spring cone nut is the quick-fix choice: the spring steel cone grips the rod thread so you can push it on and set position without running a nut up the full length of rod, which is why electrical and mechanical crews use them on hanger rod drops. A plain hex nut, or a hex nut with a washer, is what you want where you need to torque a joint to a repeatable clamp load. The MSNRCN1213 is sized for 1/2-13 rod.
4) How much space does a 1/2-13 spring cone nut take up on the rod?
Each nut measures 1.316 to 1.380 in fastener length, 0.725 to 0.770 in width, and 0.463 to 0.481 in height. Those ranges matter when you are working in a tight ceiling cavity or close to a strut face, since the cone body is longer than a hex nut of the same thread size.
5) What are Metallics spring cone nuts made of, and will the zinc finish hold up indoors?
Steel, in the C1015 to C1020 low-carbon range, with a zinc finish. Zinc plating is an indoor and dry-location coating, so it suits interior ceiling drops, strut and conduit support. For exterior, wet, or corrosive environments, specify a stainless or hot-dip galvanized hanger fastener instead.
6) How many spring cone nuts come in a box, and can I buy fewer than a full box?
The MSNRCN1213 ships as a box of 100 with a 100-count order minimum, so a single box is the smallest purchase. Metallics does offer other sizes and quantities by request if 1/2-13 or a 100-pack is not what the job needs.
7) How hard is the spring steel on a Metallics cone nut, and why does that matter?
Hardness is Rockwell HR15N 78-90. The cone has to be hard enough to bite and hold on the rod thread while still springing open as it is pushed on, which is what the superficial-scale reading documents. If a submittal asks for fastener hardness on hanger components, that is the value to list.
8) What does a box of 100 Metallics 1/2-13 spring cone nuts weigh for shipping or a material takeoff?
A full box runs 9.2 lbs, with carton dimensions of 7.25 x 6.75 x 3.25 inches. That is useful if you are staging material by floor or loading out multiple boxes for a ceiling rough-in.
