Metallics JN163D – Frequently Asked Questions
1) Are Grade 2 zinc hex nuts strong enough for the bolts I'm using on a strut or conduit job?
Grade 2 nuts match any low carbon bolt or screw that has not been heat treated, with a specified minimum tensile strength of 74,000 psi or less. Hardness runs Rockwell B68 to C32. If you are bolting with Grade 5 or Grade 8 fasteners, step up to a nut of the same grade instead, since the nut should never be the weak link.
2) How thick is the nut, and will it clear a tight space behind a panel?
Nut height is 0.212 to 0.226 inches, so figure just under a quarter inch of stack behind the work, plus whatever bolt thread protrudes past it. That is standard American Standard hex nut height for 1/4-20.
3) How many nuts come in the Metallics JN163D jar, and can I buy a smaller quantity?
It ships as a jar of 100, and 100 count is the order minimum. Metallics does offer other sizes and quantities by request, but the JN163D itself is the 100 piece jar.
4) Is zinc plated steel okay outdoors, or do I need stainless?
The JN163D is zinc plated steel, silver in appearance. Zinc plating handles dry indoor and protected locations well, but for wet exterior runs, washdown areas, or anywhere corrosive, go to 18-8 or 316 stainless instead. Zinc plating is a sacrificial coating, not a corrosion proof one.
5) Does this hex nut meet Buy American requirements for a government or institutional project?
Metallics lists the JN163D as both ARRA compliant and Buy American compliant, with country of origin recorded as multiple. For a federally funded job, keep the compliance record with your submittal package.
6) What does a jar of 100 Metallics 1/4-20 hex nuts weigh for shipping?
0.74 lbs for the jar. Handy if you are packing a van stock order or estimating freight on a multi jar pull.
