Metallics JN150 – Frequently Asked Questions
1) What screw size does the Metallics JN150 hex nut thread onto?
The JN150 is a 2-56 hex nut, so it mates with a #2 machine screw cut at 56 threads per inch (UNC for the #2 size). It will not thread onto a #2-64 fine thread screw or any #3 or #4 screw. These small sizes show up on device plates, fixture canopies, and small terminal hardware.
2) Will a 2-56 zinc plated steel nut hold up in a damp or outdoor electrical box?
The JN150 is steel with a zinc finish, which is a plating for general indoor and dry-location use. Zinc gives mild corrosion resistance but it is not a wet-location or coastal material, and once the plating is scratched the steel underneath will rust. For exterior, washdown, or corrosive environments, specify a stainless nut instead.
3) What grade are these Metallics 2-56 hex nuts, and is that strong enough for a machine screw assembly?
Grade 2 steel, with hardness measured at Rockwell B68 to C32. Grade 2 is the standard commercial strength class for general fastening and is what a #2 machine screw assembly normally calls for. If the drawing specifies a higher strength class, a Grade 2 nut is not a substitute.
4) Do these small hex nuts meet a dimensional standard so they match other brands on the job?
Yes, the JN150 is made to ASME B18.2.2, the dimensional standard for hex nuts. That means across-flats and thickness match any other B18.2.2 2-56 nut, so wrench and socket sizes and stacked thread engagement work the same as whatever is already in the panel.
5) Can Metallics JN150 nuts be used on a federally funded or Buy American job?
The JN150 is flagged compliant for both ARRA and Buy American, while the country of origin is listed as China. Agency and project rules vary on how those two facts interact, so procurement should match the compliance flag against the specific clause in the contract.
6) How many 2-56 nuts come in the Metallics JN150 jar?
One hundred nuts, packaged in a jar, and 100 count is also the order minimum. The jar keeps loose small fasteners contained on a service truck, which matters at this size. Metallics notes other sizes and quantities are available by request.
7) What does a jar of 100 Metallics 2-56 hex nuts weigh and how much shelf space does it take?
Shipping weight is 0.95 lbs for the jar of 100, with package figures of 3 x 3 x 2.15 inches. That fits a single bin slot in a van shelf or a parts drawer on a stocking cart.
