Metallics JPMP86 8-32 x 1 in. Pan Head Phillips Machine Screws - Steel Zinc - Each

8-32 is the standard thread for device mounting in outlet and switch boxes, and the Metallics JPMP86 is an 8-32 screw with 32 threads per inch cut to the ASME B18.6.3-2010 dimensional standard, so it mates with factory 8-32 tapped holes in boxes, mud rings and plaster rings. At 1 inch long it gives extra reach when a device sits proud of a deep ring or behind added drywall; for a flush-mounted device a shorter screw is usually enough.

No. The JPMP86 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing language in the spec, you will need a domestically produced machine screw instead.

A #2 Phillips. The recess is a Phillips drive with a 0.175 in. recess diameter and a gaging depth of 0.071 to 0.097 in., so a #2 bit seats fully. A #1 will cam out and a #3 will not bottom in the recess.

The pan head measures 0.306 to 0.322 in. across and stands 0.105 to 0.115 in. above the surface. That is a low, broad head, so it bears across a slotted or oversized hole without pulling through and only projects about a tenth of an inch, which matters when a cover plate or enclosure door has to close over it. If you need the fastener flush with the surface, a pan head is the wrong head style for you.

These are carbon steel with a zinc finish, made from AISI 1006 to 1022 steel. Zinc plating is a mild corrosion barrier intended for dry indoor use, so for wet locations, exterior enclosures or washdown areas a stainless machine screw is the better call. Indoors in panels, boxes and equipment, zinc plated steel is the normal choice.

The JPMP86 is rated at 60,000 psi minimum tensile strength with a surface hardness of Rockwell B70 to B100. That is ordinary low carbon steel strength, fine for mounting devices, covers, brackets and equipment, but it is not a grade 5 or grade 8 fastener. Do not substitute it where a structural or high torque bolt is specified, and go easy on an impact driver in a tapped sheet metal hole.

It is a general purpose fastener for the electrical, plumbing, and heating and air conditioning trades. Typical uses are mounting devices and cover plates in boxes, hanging small brackets and straps, and fastening into tapped holes in sheet metal enclosures and equipment. Because it is a machine screw and not a self tapping screw, it needs an existing 8-32 tapped hole or a nut on the back side.

They ship in a jar, with a minimum of 100 screws per jar. One jar weighs 0.66 lbs. Buy by the jar rather than the piece if you are stocking a van or a maintenance shop.

Yes. The PMP series pan head Phillips machine screws are offered in other sizes and quantities by request, so if 1 inch is too long or too short for your hole depth, or you need a larger count than the 100 piece jar, ask for the alternate size.
