Metallics JPMP24 6-32 x 5/8 in. Pan Head Phillips Machine Screws - Steel Zinc - Each

Yes. The JPMP24 is a 6-32 machine screw, which is the standard thread used for switch and receptacle mounting, box ears, and cover plates on steel boxes. Thread pitch is 32 threads per inch and the shank is 5/8 in. long, so it has enough reach for a device yoke plus a plaster ring or box ear, while still being short enough not to bottom out in a shallow box.

No. The JPMP24 is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your project has domestic sourcing requirements, these will not satisfy them.

A machine screw like the JPMP24 has a uniform 32 TPI thread with a blunt end, so it needs an existing tapped hole or a nut. If you are fastening into bare sheet metal or an untapped hole with nothing to thread into, you want a self-tapping or sheet metal screw instead. For switch boxes, device yokes, panels and brackets that already carry 6-32 threads, this is the correct type.

A #2 Phillips bit. The recess is a Phillips with a 0.159 in. recess diameter and a gaging depth of 0.055 to 0.080 in., so a #2 seats fully; a #1 will cam out and chew the recess, and a #3 will not seat.

Head height runs 0.087 to 0.097 in. and head width 0.256 to 0.27 in. That is a low, round-topped pan profile just over a quarter inch across, so it covers a clearance hole on a plate or bracket without the broad footprint of a truss head and without needing a countersink the way a flat head does.

They are made to ASME B18.6.3-2010, the dimensional standard for inch-series machine screws, so head, thread and recess dimensions match any other 6-32 x 5/8 pan head Phillips screw built to that same standard. If you are topping up a bin of generic 6-32 hardware, these drop straight in.

Zinc plating on steel is a mild corrosion barrier meant for dry indoor service, panel work, and interior device mounting. For wet locations, exterior enclosures, or washdown areas, go with a stainless machine screw instead of this zinc plated steel version.

The JPMP24 is low carbon steel per AISI 1006-1022, with 60,000 psi minimum tensile strength and a Rockwell B70 to B100 hardness range. That is standard commercial machine screw strength, fine for mounting devices, covers, brackets and panel hardware. It is not a graded structural fastener, so do not substitute it where a Grade 5 or Grade 8 bolt is specified, and do not over-torque into thin sheet metal threads.

They ship in a jar of 100, and 100 count is the order minimum. Useful format for a service van or a shop bench since the jar keeps the loose 6-32 hardware together.
