Metallics JPMP86BR Screw 8-32 x 1 PN PH MS BR (Jar 100)

Yes. 8-32 is the standard thread used for device mounting screws, switch and receptacle straps, cover plates and box ears in North American electrical work, and this is an 8-32 machine screw with a 1 inch length, so it threads straight into those tapped holes. The extra length is what you want when a device sits proud of the box or you're reaching through plaster rings and spacers; for a flush-mounted device a shorter 8-32 is usually the better pick.

100 screws per jar. Metallics packs this one in a jar rather than a box, which is the format MRO cribs and service vans tend to want for loose fasteners you grab by the handful.

The JPMP86BR is a brass-finish 8-32 x 1 pan head Phillips machine screw, which is what you use when the screw head will show against brass or bronze-tone wall plates and the plain plated screw would stand out. Head style is pan, so it sits slightly domed rather than flush.

Order Metallics JPMP86BR. That part number covers the 8-32 x 1 inch pan head Phillips machine screw in brass, jar of 100, and it is the only configuration sold under that number, so there is nothing further to specify on the order.

Wrong fastener for drywall or wood. A machine screw has a uniform straight thread (8-32 here) meant for a pre-tapped metal hole or a nut, and it will not hold in wood or gypsum. Use it for device straps, box ears, enclosure covers and panel hardware; for wood framing or drywall you need a wood screw, a self-drilling screw, or a drywall anchor instead.
