Metallics JHHMS48 – Frequently Asked Questions
1) Will a Metallics JHHMS48 10-32 machine screw thread into a standard electrical box or device ground screw hole?
The JHHMS48 is a 10-32 thread machine screw, which is the thread used for ground screws and device mounting holes in standard steel outlet and switch boxes. Threads are cut to ANSI/ASME B1.1 at 32 threads per inch, so it will run into any tapped 10-32 hole. Length is 3/4 inch, which is long enough to pick up a bonding jumper or a mounting bracket but short enough that it is not bottoming out in a shallow box boss.
2) How many 10-32 x 3/4 machine screws come in the Metallics JHHMS48 jar?
One hundred screws, packed in a jar, and 100 count is the order minimum. Net weight of the jar is 336 g. That jar size is aimed at a van or shop bin rather than a single-device repair, and the washer-face hex head means you can grab them for ground screws, cover plates and bracket work out of the same container.
3) Are these Metallics hex machine screws plated for damp or exterior-adjacent locations?
They are zinc plated steel. Zinc plating handles indoor and dry or occasionally damp locations fine, which covers most panel, box and bracket work. For sustained wet exposure, direct weather, or coastal and corrosive environments, specify stainless rather than zinc plated steel.
4) Do these Metallics screws meet Buy American requirements on a federal or public job?
The JHHMS48 is flagged Buy American compliant and ARRA compliant in the manufacturer data, with country of origin listed as China. Procurement officers on federally funded work should read both of those together, since the compliance flag and the origin are separate declarations by the manufacturer.
5) What dimensional standard do the Metallics JHHMS hex machine screws follow?
Head geometry follows ASME B18.6.3-2002, the standard for machine screws and tapping screws, and the thread follows ANSI/ASME B1.1. If a submittal or spec section calls out B18.6.3 machine screws, the JHHMS series answers that line, and the stated head width of 0.305 to 0.312 inch and washer OD of 0.384 to 0.414 inch are the figures to drop into the submittal.
