Metallics MSNS1420 – Frequently Asked Questions
1) What thread size is the Metallics MSNS1420 spring nut, and will a standard 1/4-20 bolt thread into it?
The MSNS1420 is a 1/4-20 spring nut, 20 threads per inch, cut to ANSI/ASME B1.1. Any standard off-the-shelf 1/4-20 machine bolt or hex head cap screw will thread straight into it.
2) Can I use Metallics MSNS1420 spring nuts on a Buy American or ARRA-funded project?
No. The MSNS1420 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing requirement, you will need a domestically produced spring nut instead.
3) What is the difference between a short spring nut and a long spring nut for strut channel?
Length is the difference, and it decides how the nut seats in the channel. The MSNS1420 is the short version, measuring 1.316 to 1.380 inches long, 0.725 to 0.770 wide and 0.231 to 0.248 high. A short spring nut uses a shorter spring and drops into the channel with less compression, which is what you want in tighter runs or where you are setting nuts close together. Long spring nuts use a taller spring to bridge deeper channel. Metallics marks the short spring versions with an asterisk in the size list, and other sizes are available by request.
4) Are Metallics MSNS1420 spring nuts okay for damp or unfinished areas?
These are steel nuts with a zinc finish, made from C1015 to C1020 carbon steel. Zinc plating handles indoor and generally dry or intermittently damp conditions, like mechanical rooms, ceiling spaces and unfinished basements. For wet exterior exposure, continuous moisture or corrosive environments, specify a stainless spring nut instead of the zinc-plated steel.
5) Do I have to buy a full box of 100 of the MSNS1420 spring nuts?
Yes. The MSNS1420 ships as a box with a 100 count order minimum, so 100 pieces is the smallest quantity. The full box weighs 6.68 lbs. If you need a different count, Metallics offers other sizes and quantities by request.
6) What trades actually use a 1/4-20 spring nut like this?
Electrical, plumbing, and heating and air conditioning work. Spring nuts go into strut channel so you can hang conduit straps, pipe clamps, duct supports and equipment with a 1/4-20 bolt anywhere along the run, without drilling or welding. The spring holds the nut in position in the channel while you start the bolt one-handed, which is why they are standard on overhead trapeze and racked conduit installs.
7) Is a bolt included with the MSNS1420 spring nut, or do I order fasteners separately?
The box contains spring nuts only, 100 of them. You supply the 1/4-20 bolts, hex cap screws or threaded rod, plus whatever strap, clamp or washer the hanger calls for. Match the bolt length to the thickness of what you are clamping plus engagement into the nut.
