Metallics JPMP36TF-1M Screw 10-32 x 5/8 PN PH Type-F MS St (Jar 1000)

Type-F is a thread cutting screw: the point carries cutting flutes that form the 10-32 thread as it goes in, so you can drive it into an untapped pilot hole in sheet metal or a casting rather than tapping it first. It also re-cuts a stripped or paint filled 10-32 hole in an existing enclosure, which is the usual reason an electrician reaches for it over a plain machine screw.

Steel, not stainless. That makes it a dry interior fastener for panels, boxes, and enclosure covers. For wet, outdoor, or corrosive locations, specify a stainless or heavily coated fastener instead.

1,000 screws, packed in a jar rather than a box, so the count is the full jar. That is a shop or service truck quantity for anyone doing repeated enclosure, device, and cover plate work rather than a single install.

5/8 inch of length is sized for thin material: sheet metal panels, box ears, cover plates, and strut style mounting where only a short grip is needed. The cutting flutes at the point take up part of that length, so for stacked washers, gaskets, or thicker assemblies step up to a longer 10-32.

Order Metallics JPMP36TF-1M. That number covers the 10-32 x 5/8 pan head Phillips Type-F steel screw in the 1,000 count jar, and it is the only configuration under that number.

A pan head sits proud of the surface with a broad flat bearing face, which is what you want for clamping a cover, strap, or bracket flat against sheet metal. If the head has to sit flush in a countersunk hole, a pan head is the wrong choice, use a flat head instead.
