Metallics MSNRCN1420 – Frequently Asked Questions
1) What thread size are Metallics MSNR spring cone nuts, and will they take a 1/4-20 bolt or rod?
The MSNRCN1420 spring cone nut is threaded 1/4-20, so it takes standard 1/4 inch bolts, screws, and threaded rod at 20 threads per inch. The thread is cut to ANSI/ASME B1.1, which is the same Unified inch standard your 1/4-20 all-thread and hardware is made to, so it runs on without chasing.
2) Are Metallics spring cone nuts made of stainless, and will the zinc finish hold up in a damp mechanical room?
These are carbon steel, not stainless, with a zinc plated finish. The steel is C1015 to C1020, a low carbon grade. Zinc plating handles indoor and normally dry conditions, interior mechanical spaces and above ceilings. For direct exposure to weather, wash down, or corrosive process areas, spec a stainless or hot dip galvanized fastener instead.
3) How many spring cone nuts come in a box of Metallics MSNRCN1420, and can I buy fewer than a full box?
They ship 100 to a jar, and 100 count is the order minimum, so a jar is the smallest quantity. For an electrical contractor hanging a run of strut or fixture supports that is usually one box per job. Other sizes and quantities can be requested.
4) Do Metallics MSNRCN1420 spring cone nuts meet Buy American and ARRA requirements for a public project?
The MSNRCN1420 spring cone nut is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so on a federally funded job where the AHJ or owner wants origin documented per lot, get the origin confirmed for the specific lot shipped.
5) What is a spring cone nut used for, and how is it different from a plain channel nut?
A spring cone nut is a strut style nut with a spring behind it that holds the nut up against the inturned lips of the channel while you start the bolt. That means one hand on the fitting instead of fishing for a loose nut overhead, which is the whole reason electricians use them for conduit clamps, fixture hangers, and trapeze supports. A plain nut without the spring costs less but has to be held in place while threading. This one is 1/4-20 in zinc plated steel.
6) How much does a box of 100 Metallics 1/4-20 spring cone nuts weigh for shipping to a jobsite?
A full jar of 100 weighs 9.3 pounds, and the packed carton runs 7.25 by 6.75 by 3.25 inches. That is a one hand carry up a ladder, so a truck stock of several boxes is not a problem.
7) I need spring cone nuts in 3/8-16 instead of 1/4-20, does Metallics make other sizes in the MSNR series?
The MSNR series runs beyond the 1/4-20 MSNRCN1420, and other sizes and quantities can be requested. Tell us the thread size you need and the channel you are mounting into and we will match it out of the series.
