Metallics JSQ7 – Frequently Asked Questions
1) Will a Metallics JSQ7 square nut thread onto a 5/16-18 strut rod or bolt?
Yes. The JSQ7 is a 5/16-18 square nut, 18 threads per inch, so it mates with any 5/16 inch coarse-thread rod, bolt, or hanger rod. It will not work on 5/16-24 fine thread.
2) What is the across-flats size of the JSQ7 square nut, and will it sit in a strut channel?
The nut measures 49/64 inch across the flats, which is the standard width for a 5/16-18 square nut and is why it drops into channel and strut slots rather than spinning like a hex nut. Metallics lists channel and strut work, along with electrical, plumbing, and HVAC, as its intended applications.
3) Does the Metallics JSQ7 square nut meet Buy American or ARRA requirements?
No. The JSQ7 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your project has domestic-sourcing language in the specification, this nut will not satisfy it.
4) Is the JSQ7 square nut plated for damp or unfinished areas?
It is steel with a zinc finish. Zinc plating handles indoor and sheltered mechanical-room conditions. For wet, washdown, or corrosive exposure, specify an 18-8 stainless square nut in the same 5/16-18 thread instead.
5) How many 5/16-18 square nuts come in a Metallics JSQ7 jar?
One hundred nuts per jar, and the jar is the minimum order unit, so you buy in full hundreds rather than loose pieces. The filled jar weighs 1.47 lbs. Metallics notes other sizes and quantities are available by request.
6) Is the JSQ7 square nut hard enough for strut and pipe hanger loads?
The steel is specified at Rockwell B68 to C32, a mid-range hardness typical of commercial-duty plated carbon steel nuts. That covers the channel, strut, conduit, and pipe hanging work Metallics lists for the JSQ series. It is not a graded structural nut, so do not substitute it where a drawing calls out a specific SAE or ASTM grade.
