Metallics JN156 – Frequently Asked Questions
1) Will the Metallics JN156 hex nut thread onto a 12-24 machine screw?
Yes. The JN156 is a 12-24 hex nut, so it mates with any #12 machine screw cut at 24 threads per inch. That is the common thread on electrical device screws, box screws, and strut fittings. It will not thread onto a 12-28 or a 1/4-20 screw.
2) Are these zinc plated steel nuts okay for outdoor or damp electrical work?
The JN156 is zinc plated steel. Zinc plating handles indoor and protected work, damp locations, and general panel and strut assembly. For direct weather exposure, wet locations, or corrosive environments, stainless is the better call.
3) What grade are the Metallics JN156 nuts and how strong is that?
Grade 2, with a hardness of Rockwell B68 to C32. That is standard commercial-duty steel, suitable for mounting devices, enclosures, brackets and strut hardware. If a drawing calls out a Grade 5 or Grade 8 fastener for a structural or high-torque joint, this is not the nut for it.
4) Do these 12-24 nuts meet a dimensional spec I can put on a submittal?
They are made to ASME B18.2.2, the standard covering hex nut dimensions, so the width across flats and the thickness fall within the published tolerances for a 12-24 hex nut. Both the Arra and Buy American compliance flags are marked C on this item; country of origin is China.
5) How many nuts come in a jar of Metallics JN156, and can I buy fewer?
The JN156 ships as a jar of 100 nuts, and 100 count is the order minimum, so the jar is the smallest unit. The jar itself measures 3 x 2.15 x 3 inches and weighs 0.56 lbs filled, which fits a van bin or a tool box tray.
6) Can I get this 12-24 hex nut in a different size or a larger quantity?
Other sizes and quantities in the Metallics JN series are available by request. The JN156 itself is the 12-24 zinc plated steel nut in a 100 count jar.
