Metallics MSNR1213 – Frequently Asked Questions
1) What thread size does the Metallics MSNR1213 spring nut take?
The MSNR1213 is a 1/2-13 spring nut, so it accepts 1/2 inch rod or bolt at 13 threads per inch, cut to ANSI/ASME B1.1. That is the standard UNC coarse pitch for 1/2 inch, so common 1/2-13 threaded rod and hex bolts thread straight in.
2) Will a 1/2-13 Metallics spring nut fit inside my strut channel?
Body size decides that. The nut measures 1.316 to 1.380 long, 0.725 to 0.770 wide, and 0.463 to 0.481 high. Measure the inside slot width of your channel against the 0.725 to 0.770 dimension and the clear interior depth against the height before ordering a box.
3) Do Metallics MSNR spring nuts qualify for a Buy American or ARRA job?
No. The MSNR1213 spring nut is not Buy American compliant and not ARRA compliant, and country of origin is listed as multiple. On a federally funded project with domestic sourcing requirements you will need a domestically produced channel nut instead.
4) Are these spring nuts OK for an outdoor or damp mechanical room?
They are steel with a zinc finish, which handles indoor and normally dry or occasionally damp conditions. Zinc plating is not a marine or continuously wet coating, so for exterior exposure or washdown areas step up to a stainless or hot dip galvanized channel nut instead.
5) How many 1/2-13 spring nuts come in a box?
They ship 100 to a box, and 100 is also the order minimum, so the smallest purchase is one full box of 100. Metallics also lists other sizes and quantities as available by request.
6) Can these spring nuts be used for plumbing and HVAC hangers, or electrical only?
Both. Metallics lists the MSNR spring nut for the electrical, plumbing, heating and air conditioning industries, so the same box covers conduit racks, pipe hangers and duct supports where 1/2-13 rod is used.
7) What steel are these channel spring nuts made from and how hard are they?
Material is low carbon steel in the C1015 to C1020 range, with a case hardness of Rockwell HR15N 78 to 90. That gives threads hard enough to resist stripping while the body stays formable for the spring action.
8) How much does a box of 100 Metallics 1/2-13 spring nuts weigh?
A full box runs 7.35 lbs, and the carton measures 7.25 by 6.75 by 3.25 inches. Useful to know if you are staging several sizes on a cart or allowing for van weight on a multi-box order.
