Metallics MSNR1420D – Frequently Asked Questions
1) What thread size is the Metallics MSNR1420D spring nut, and will standard 1/4-20 bolts thread into it?
It is a 1/4-20 spring nut, 20 threads per inch, cut to the ANSI/ASME B1.1 thread standard. Any standard 1/4-20 UNC bolt or threaded rod will thread into it.
2) What are the actual dimensions of the MSNR1420D spring nut for fitting inside a strut channel?
The body runs 1.316 to 1.380 inches long, 0.725 to 0.770 inches wide, and 0.231 to 0.248 inches high. The width is what matters most: it has to clear the open lip of your channel and then turn a quarter so the serrated edges seat behind the lips. Measure your channel's lip opening before ordering.
3) Is the Metallics 1/4-20 spring nut OK for a Buy American or ARRA-funded job?
Yes. The MSNR1420D is made in the United States, flagged Buy American compliant and ARRA compliant, so it clears domestic-content requirements on federally funded work.
4) Are these spring nuts zinc plated enough for a damp indoor mechanical room?
They are steel with a zinc finish, which handles dry interior and typical indoor mechanical-room conditions. For wet exterior or corrosive environments, specify a stainless or hot-dip galvanized channel nut instead.
5) How many spring nuts come in a box of Metallics MSNR1420D?
They ship as a box of 100, and 100 count is the order minimum, so you buy in full boxes rather than loose pieces. Metallics notes other sizes and quantities are available by request.
6) Does the MSNR1420D spring nut include the spring and the bolt?
The spring nut comes with its spring attached, which is what holds it in position in the channel while you start the bolt one-handed. Bolts are not included, so order 1/4-20 hardware separately to match your strut and bracket thickness.
7) What grade of steel is the Metallics MSNR spring nut made from?
C1015 to C1020 low-carbon steel. That is the usual mild-steel range for channel nuts, formed and zinc plated, and it is what gives the serrated face enough bite into the channel lip without being brittle.
