Metallics JG8N163 – Frequently Asked Questions
1) What thread size are the Metallics JG8N163 hex nuts, and will they fit a 1/4-20 bolt?
They are 1/4-20 nuts, 20 threads per inch, so they thread onto any standard 1/4-20 UNC bolt, rod, or screw. Dimensions follow ANSI/ASME B182.2, so they interchange with other B182.2 1/4-20 hex nuts already on the job.
2) Is a Grade 8 nut stronger than the Grade 5 nut I normally use, and does it matter which I pick?
Grade 8 is the higher-strength hardened steel nut, tested at Rockwell C24-32 hardness, and it is what you want on a Grade 8 bolt so the nut is not the weak link in the joint. Pairing a Grade 8 nut with a lower-grade bolt gains you nothing; the bolt still governs. For vibration-prone or high-load anchorage, match grades.
3) Are Metallics JG8N163 hex nuts acceptable on a Buy American or ARRA-funded project?
No. These nuts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On federally funded or domestic-content-restricted work you will need a domestically sourced Grade 8 hex nut instead.
4) Are the Metallics JG8N163 nuts suitable for outdoor or damp mechanical room installs?
They are zinc plated hardened steel, which handles normal indoor and sheltered-exterior service and resists the incidental moisture in a mechanical or boiler room. Zinc plating is not a marine or chemically aggressive coating, so for continuous wet exposure or coastal work step up to stainless or hot-dip galvanized fasteners.
5) How many nuts come in a jar of Metallics JG8N163, and can I buy fewer?
They ship as a jar of 100, and the jar is the minimum order unit. Other sizes and quantities are available by request if 100 pieces of 1/4-20 is not what the job calls for.
6) What trades actually use these zinc Grade 8 hex nuts?
They are stocked for electrical, plumbing, heating and air conditioning work, the everyday 1/4-20 nut for strut and channel assemblies, conduit and pipe hangers, equipment mounting, and panel and enclosure hardware. A jar of 100 on the truck covers most of that without a trip to the counter.
7) What steel are these Grade 8 nuts made from?
AISI 1021 through 1045 carbon steel, hardened and zinc plated. That is the medium-carbon range that lets the nut hold Rockwell C24-32 and carry Grade 8 load without the brittleness of a higher-alloy heat treat.
8) How much does a jar of 100 of the 1/4-20 Grade 8 nuts weigh for shipping or truck stock?
The jar comes in at 0.74 lbs, in a container measuring 3 x 3 x 2.15 inches, so it drops into a van bin or gang box without taking a shelf.
