Metallics JG5N166D – Frequently Asked Questions
1) Will a Metallics JG5N166D hex nut thread onto 1/2-13 all-thread rod?
Yes. The JG5N166D is a 1/2 inch hex nut cut 13 threads per inch, which is standard 1/2-13 UNC coarse thread. It runs on 1/2-13 threaded rod, anchor bolts and cap screws. It will not fit 1/2-20 fine thread.
2) Is a Grade 5 hex nut strong enough for hanging electrical conduit and strut from Grade 5 rod?
Yes, and it is the matched choice. Grade 5 nuts are made to be run on Grade 5 bolts and rod so the fastener, not the nut, governs the joint. The JG5N166D is hardened steel at Rockwell C32. If your drawing calls out Grade 8 fasteners, step up to a Grade 8 nut instead of mixing grades.
3) Do these hex nuts meet Buy American requirements on a federally funded job?
Yes. The JG5N166D hex nuts are made in the United States and flagged compliant for both Buy American and ARRA, which is what a government, school or healthcare procurement file usually needs on a fastener line item.
4) What wrench or socket size do I need for these 1/2 inch 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 size to grab. Corner to corner it runs 0.840 to 0.866 inch, which matters if you are working it inside a tight strut channel or a recessed pocket.
5) How many nuts come in a jar of Metallics JG5N166D, and can I buy fewer?
They ship 50 to the jar, and 50 count is the order minimum, so the jar is the smallest unit. Total jar weight is 1.82 lbs. Other sizes and quantities are available by request.
6) What dimensional standard do these 1/2-13 hex nuts conform to, and will they match the nuts already on my job?
Dimensions follow ANSI/ASME B182.2, so the nut interchanges with any other finished hex nut built to that standard in 1/2-13. Steel is in the AISI 1008 to 1026 range. If the existing nuts on your racking are 3/4 inch across the flats in 1/2-13, these drop right in.
7) Is the zinc finish on these nuts suitable for outdoor or damp locations?
The finish is zinc plating over steel, which handles indoor and protected areas well, mechanical rooms, ceiling racking, interior strut. For exterior exposure, wet wells or coastal air, zinc plated steel will eventually bloom and seize; stainless or hot dip galvanized is the better call there.
8) How thick is the nut itself, for figuring thread engagement on threaded rod?
Nut height runs 0.427 to 0.448 inch. On 1/2-13 thread that is roughly six full threads of engagement, enough to develop the bolt's rated strength, so you do not need to double nut for strength alone. Double nutting is still worth it where vibration is in play.
