Metallics JG5N163 – Frequently Asked Questions
1) What thread does the Metallics JG5N163 hex nut take, and will it fit a 1/4-20 bolt?
It's a 1/4-20 nut, 20 threads per inch on a 1/4 inch coarse thread, so it mates with any standard 1/4-20 UNC bolt, screw or threaded rod. Dimensions follow ANSI/ASME B182.2, which is the hex nut dimensional standard, so it seats in a standard socket or wrench without surprises.
2) Do these Metallics hex nuts qualify for a Buy American or ARRA funded job?
No. The JG5N163 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded or domestic-content job where fasteners fall under the requirement, you need a domestically sourced nut instead.
3) What wrench or socket size do I need for these 1/4-20 Grade 5 hex nuts?
Across the flats the nut measures 0.423 to 0.438 in., which is the 7/16 inch hex a 1/4-20 nut normally carries, so a 7/16 socket or open end wrench is what you want on the truck. Across the corners it runs 0.488 to 0.505 in., useful if you're checking clearance in a tight channel or box.
4) Can I use these zinc plated hex nuts outdoors or in a damp mechanical room?
Zinc plating over hardened steel handles indoor and sheltered service, damp mechanical rooms, ceiling spaces, electrical rooms. It is not stainless. For direct weather exposure, wash-down, coastal air or anywhere standing moisture sits on the hardware, go to a hot dip galvanized or stainless nut instead.
5) How are these 1/4-20 Grade 5 nuts packaged, and what is the smallest quantity I can order?
They ship in a jar of 100, and the jar is the minimum order unit, so 100 pieces is the smallest buy. The jar weighs 0.75 lbs, which keeps a count on hand for a service van or a shop bin without loose nuts rolling around a parts drawer. Other sizes and quantities are available by request.
6) What trades actually use this nut, and what is it typically holding?
Metallics lists it for the electrical, plumbing, heating and air conditioning industries. In practice that's 1/4-20 strut and channel hardware, hanger rod and clevis work, panel and enclosure mounting, duct hanger brackets, and equipment feet, the places a Grade 5 nut with a 7/16 hex gets run down with a cordless driver.
7) What steel are these Grade 5 hex nuts made from?
Hardened steel in the AISI 1008 to 1026 range, heat treated to Rockwell C32. That's a low to medium carbon steel, which is why the zinc plating matters for corrosion, and it is not magnetically or chemically equivalent to a 300 series stainless nut if a spec calls for non-magnetic or food-grade hardware.
