Metallics JSPMP3FSS Screw 10-32 x 3/4 PN PH Type-F MS 1 (Jar 100)

Type-F is a thread cutting point. The screw has machine screw threads with a blunt, slotted cutting end, so it cuts its own mating thread in an untapped or partly obstructed hole in sheet metal, castings, or plastic instead of needing a pre-tapped 10-32 hole. Handy when a box or strap hole is painted over, damaged, or never tapped in the first place.

Yes. Because the JSPMP3FSS carries standard 10-32 machine screw threads, it threads into an existing tapped 10-32 hole the same as a plain machine screw, and the cutting point only does work when the hole is untapped. That means one jar covers both situations on a trim-out, rather than carrying two bins of fasteners.

100 screws, packed in a jar. The jar is the practical part for an electrician's van or a shop bench: it reseals, it labels, and it doesn't spill the way a bagged count does when it rides around in a tool bag.

Order it as Metallics JSPMP3FSS. That one number covers the 10-32 x 3/4 inch pan head Phillips Type-F machine screw in the 100 count jar, so there is no size or pack option to pick on top of it.

Phillips drive, so a standard #2 Phillips bit or screwdriver handles it. The head is a pan head, which seats flat against the surface with a low rounded crown rather than sinking flush, so plan on it standing slightly proud. If you need the fastener to disappear into a countersunk hole, a pan head is the wrong profile.

Metallics sells it as an electrical fastener, and the 10-32 thread is the giveaway, that's the device and box mounting thread in the trade rather than a general construction size. It still works anywhere a 10-32 pan head machine screw is called for, but it's stocked for electrical rough-in and trim work.
