Metallics JRMB85 8-32 x 3/4 in. Round Head Slotted Machine Screws - Brass - Each

The JRMB85 is an 8-32 machine screw with 32 threads per inch cut to ANSI/ASME B1.1, which is the thread form used for device box and cover plate tapped holes. At 3/4 inch long it gives more reach than the short screws that ship with most devices, useful when a box is set back behind thick plaster or tile.

No. The JRMB85 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements you'll need a domestic-origin fastener instead.

Brass is the material on the JRMB85, and brass fasteners are chosen where corrosion resistance and non-magnetic, conductive hardware matter, for example grounding connections, damp locations, and marine or outdoor enclosures. Brass is softer than steel, so don't drive it with impact tools; a hand screwdriver seated in the slot is the right approach.

These ship 100 to a jar, and 100 is the order minimum. If you need a different count or a different length in the same round head slotted brass, other sizes and quantities are available by request.

Head height is 0.107 to 0.12 inch and head width is 0.287 to 0.309 inch, dimensioned to ASME B18.6.3. That domed profile sits proud of the surface rather than flush, so if you need the screw head buried in a countersunk plate or device, a round head is the wrong choice and a flat head 8-32 is what you want.

Metallics lists the JRMB85 for electrical, plumbing, heating and air conditioning work. In practice that means device and plate mounting, strap and clamp fastening, grounding hardware, and general enclosure work where a machine-threaded screw goes into a tapped hole or a nut rather than into wood.

Product weight is listed at 0.54 lbs for the jar, which measures 3 inches long by 3 inches wide and 2.15 inches high. Easy to keep a couple of jars on the truck.
