Metallics JG5N166 – Frequently Asked Questions
1) Will a Metallics JG5N166 hex nut thread onto 1/2-13 UNC all-thread rod?
Yes. The JG5N166 is a 1/2 inch nut cut at 13 threads per inch, which is standard 1/2-13 UNC coarse thread. It will run onto 1/2-13 threaded rod, bolts, or hanger rod. It will not fit 1/2-20 fine thread.
2) Is a Grade 5 nut strong enough for seismic bracing and pipe hanger rod?
Grade 5 hardened steel at Rockwell C32 is the medium-carbon heat-treated class, which is what's normally paired with Grade 5 bolts and threaded rod on mechanical, electrical, and plumbing hanger work. Metallics lists it specifically for electrical, plumbing, heating and air conditioning use. If your drawing calls for a Grade 8 nut, this is not a substitute.
3) Are Metallics JG5N166 hex nuts Buy American or ARRA compliant for a federal job?
No. The JG5N166 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing requirements you'll need a domestic Grade 5 nut instead.
4) What wrench or socket size do I need for these 1/2-13 Grade 5 hex nuts?
Across the flats the nut measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the right size. Corner to corner it runs 0.840 to 0.866 inch, which is what matters if you're working in a tight channel or strut.
5) Can these zinc plated hex nuts be used outdoors or in a damp mechanical room?
The finish is zinc plating over hardened steel, which handles indoor and normally dry or occasionally damp conditions. It is not stainless, so for continuous wet exposure, coastal, or corrosive environments you want hot dip galvanized or stainless hardware instead.
6) How many nuts come in a jar of Metallics JG5N166, and what is the minimum order?
Each jar holds 50 nuts, and 50 each is the order minimum, so one jar is the smallest buy. Metallics offers other sizes and quantities by request.
7) Do these nuts meet a dimensional spec I can cite on a submittal?
Dimensions are to ANSI/ASME B182.2 and the steel is AISI 1008 through 1026. Those two callouts plus the Grade 5 designation are usually what a submittal reviewer is looking for on hardened hex nuts.
8) How much does a 50 count jar of 1/2-13 Grade 5 hex nuts weigh?
1.82 lbs per jar, and the jar itself is about 3 x 3 x 3.6 inches. Light enough to keep several sizes on the truck without eating bin space.
