Metallics JN178 – Frequently Asked Questions
1) What thread size does the Metallics JN178 hex nut take?
It's a 1-1/4-7 nut, meaning a 1-1/4 inch nominal diameter at 7 threads per inch. That's the standard UNC coarse pitch for 1-1/4 inch rod and bolt, so it threads onto 1-1/4 inch all-thread and anchor rod without an adapter. Dimensions follow ASME B18.2.2, the inch hex nut standard, so the across-flats size matches any other B18.2.2 heavy or finished hex nut of the same callout.
2) Does the Metallics JN178 nut meet Buy American and ARRA requirements for a public project?
The JN178 is flagged compliant for both ARRA and Buy American, with country of origin listed as China. On federally funded work, confirm which clause your contract actually invokes, because the two have different domestic-content tests.
3) How many 1-1/4-7 nuts come in a jar, and can I buy fewer?
The JN178 ships as a jar of 25 nuts, and 25 count is the order minimum, so a single jar is the smallest buy. Other sizes and quantities can be had by request.
4) Will zinc plated nuts hold up outdoors or in a damp mechanical room?
Zinc plating over steel is what this nut carries, which is a sacrificial coating suited to dry interior and protected locations. It handles a mechanical room or a covered exterior run, but direct weather exposure, wash-down areas, coastal air, or anything in contact with treated lumber will eat zinc plating. Those applications call for hot-dip galvanized or stainless nuts rather than zinc plated steel.
5) Can I mix these nuts with 1-1/4 inch nuts already on my job from another supplier?
Yes, as long as the existing ones are also 1-1/4-7 inch coarse thread. Because the JN178 is dimensioned to ASME B18.2.2, the thread form and hex sizing are interchangeable with any other B18.2.2 nut of the same callout, so one wrench size covers both and either nut runs on the same rod. Watch the grade if the assembly is engineered: this one is Grade 2.
