Metallics JHHMS70 – Frequently Asked Questions
1) What thread does the Metallics JHHMS70 10-32 machine screw use, and will it thread into a standard 10-32 tapped box or panel?
It's a 10-32 thread, 32 threads per inch, cut to ANSI/ASME B1.1 in the UNF series. That's the same 10-32 found in tapped holes on electrical boxes, panel rails, and device mounting ears, so it threads straight into any 10-32 tapped hole or 10-32 nut. Length is 1-1/2 inches.
2) Can the JHHMS70 hex machine screw be driven with a screwdriver, or do I need a wrench or nut driver?
Both work. The head is a hex with a slot in it, so you can run it with a flat blade screwdriver in tight quarters or seat it with a nut driver or wrench when you want more torque. Head width across the flats measures 0.305 to 0.312 inch, which is the 5/16 inch nut driver size.
3) Does the Metallics JHHMS70 meet Buy American and ARRA requirements for a public works job?
The JHHMS70 is flagged compliant for both ARRA and Buy American in the manufacturer's data. Country of origin is China, so if your specification requires domestic melt and manufacture rather than ARRA-style compliance, verify the wording of your project spec against that origin.
4) Is the Metallics 10-32 x 1-1/2 a coarse or fine thread, and can I mix it with 10-24 screws already on site?
10-32 is the fine thread (UNF) in the #10 size, 32 threads per inch. It will not interchange with 10-24 coarse hardware. If the tapped holes or nuts on your panel are 10-24, these will cross-thread and strip, so match the thread count before mixing stock in the same jar or pouch.
5) Is the Metallics 10-32 hex head machine screw plated for corrosion resistance, and is it OK in a damp mechanical room?
Steel with a zinc finish. Zinc plating handles normal indoor and damp-interior service like mechanical rooms, panel enclosures, and strut work. For direct outdoor exposure, washdown, or coastal air, step up to stainless rather than zinc-plated steel.
6) How many 10-32 x 1-1/2 screws come in the Metallics JHHMS70 jar?
100 pieces in a jar, and 100 count is also the order minimum, so one jar is the smallest buy. The filled jar weighs 553 g.
7) What size washer fits the JHHMS70 10-32 hex head screw?
A #10 flat washer with an outside diameter of 0.384 to 0.414 inch is the matching size for this screw. Washers and nuts are not included in the jar, so order those separately if the hole is oversized or you are through-bolting rather than threading into a tapped hole.
8) Is this 10-32 hex machine screw made to a recognized dimensional standard for submittals?
Dimensions follow ASME B18.6.3-2002, the standard covering machine screws, with threads to ANSI/ASME B1.1. Those two references are what a submittal reviewer looks for, along with head width across flats of 0.305 to 0.312 inch.
