Metallics JSQ8 – Frequently Asked Questions
1) What thread does the Metallics JSQ8 square nut take?
The JSQ8 is a 3/8-16 square nut, so 16 threads per inch on a 3/8 inch diameter bolt or rod. That is the standard UNC coarse pitch for 3/8 inch, so it runs on common 3/8 inch coarse-thread hanger rod and strut bolts.
2) Will a 3/8-16 square nut fit inside a strut channel slot?
Across the flats the JSQ8 measures 55/64 inch, which is what decides whether it drops into your channel. Metallics lists it for channel and strut work alongside electrical, plumbing and HVAC applications, so it is intended to be held in a channel slot or against a flat while you run the bolt up. Measure your slot opening against the 55/64 figure before you commit to a jar.
3) Can these nuts be used on a federally funded or Buy American job?
No. The JSQ8 square nut is listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. If your contract carries a domestic-sourcing clause, this part will not satisfy it and you need a domestically produced 3/8-16 square nut.
4) Are these square nuts plated for damp or outdoor use?
The JSQ8 is steel with a zinc finish. Zinc plating handles normal indoor and protected locations fine, but it is not a stainless part, so for wet, washdown, coastal or corrosive environments you want 18-8 stainless square nuts in the same 3/8-16 thread instead.
5) How many square nuts come in a jar of Metallics JSQ8?
One hundred nuts per jar, and the jar is the order unit, so you buy in multiples of 100 rather than by the piece. The jar weighs 2.45 lbs. Metallics notes other sizes and quantities are available by request if 100 of the 3/8-16 is not the count you need.
6) Should I use a square nut or a hex nut for strut and channel hangers?
A square nut like the JSQ8 is the one you want where the nut has to be held against turning, because the flats key into a channel slot or sit flat against a surface and stop it spinning while you drive the bolt. A hex nut needs a wrench on it. For general bolted connections where you can get two wrenches on the joint, a 3/8-16 hex nut is simpler; for strut, channel and electrical or mechanical hanger work, which is what Metallics lists this nut for, the square is the right shape.
7) How hard is the Metallics JSQ8 square nut, and will the threads strip?
Hardness runs Rockwell B68 to C32, which puts it in the normal range for a plated carbon steel nut. It will carry a standard 3/8-16 bolt tightened to typical hanger and strut torques without the threads deforming, but it is not a hardened high-strength nut, so do not pair it with a high-grade bolt you intend to torque to full capacity.
8) What is the Metallics part number for a 3/8-16 zinc square nut?
JSQ8, from the Metallics JSQ square nut series. Order that number and you get the 3/8-16 steel, zinc plated square nut in a jar of 100.
