Metallics MSNR1420 – Frequently Asked Questions
1) What thread size are the Metallics MSNR1420 spring nuts, and will standard 1/4-20 bolts thread into them?
The MSNR1420 spring nut is tapped 1/4-20, meaning a 1/4 inch diameter thread at 20 threads per inch, cut to ANSI/ASME B1.1. Any standard 1/4-20 UNC hex bolt, hanger rod stud, or strut bolt will thread straight in.
2) What are the actual body dimensions of the MSNR1420 spring nut so I can tell if it fits my channel?
Each nut runs 1.316 to 1.380 for fastener length, 0.725 to 0.770 for width, and 0.231 to 0.248 for height, in inches. That width puts it in the range that drops into standard 1-5/8 inch strut channel with a 7/8 inch throat, and the height is the uncompressed stack including the spring. Measure your channel opening against the 0.725 to 0.770 figure before committing to a box.
3) Can I use Metallics MSNR1420 spring nuts on a Buy American or ARRA funded job?
No. The MSNR1420 is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. On a federally funded project with domestic sourcing requirements you will need a domestically produced spring nut.
4) How many spring nuts come in a box of Metallics MSNR1420, and can I buy fewer?
They ship as a box of 100, and 100 count is the order minimum, so it is a full box or nothing on this item. Metallics does make other sizes and quantities available by request.
5) Are Metallics MSNR1420 spring nuts okay for damp or outdoor strut runs?
These are steel nuts with a zinc finish, made from C1015 to C1020 low carbon steel. Zinc plating handles indoor and sheltered conditions, mechanical rooms, and ceiling spaces. For sustained outdoor exposure, washdown, or corrosive environments, step up to a hot dip galvanized or stainless spring nut instead.
6) What trades use a 1/4-20 spring nut like this, and what is it actually for?
A spring nut drops into the slot of strut channel and the spring holds it in position while you start the bolt, so you can set hangers and supports one handed overhead. Metallics lists the MSNR series for the electrical, plumbing, and heating and air conditioning trades, typical work being conduit straps, pipe clamps, cable tray supports, and duct hangers off 1/4-20 hardware.
7) How much does a box of 100 Metallics MSNR1420 spring nuts weigh and how big is the carton?
The box of 100 comes in at 6.68 lbs, with carton figures of 7.25 by 6.75 by 3.25 inches. Easy enough to carry several boxes up a lift for a day of overhead strut work.
8) I need 3/8-16 or 1/2-13 spring nuts instead of 1/4-20. Does the Metallics MSNR series cover those?
The MSNR1420 itself is 1/4-20 only, that is the single model on the series. Metallics does offer the MSNR spring nut in other sizes and quantities by request, so a larger thread can be sourced under the same series rather than switching product lines.
