Metallics JSTPO10 Screw 12 x 1 OV PH TS 18-8 SS (Jar 100)

It's a #12 x 1 inch screw with an oval head and a Phillips drive, made of 18-8 stainless steel. The oval head sits partly flush when driven into a countersunk or dimpled hole, so it's the choice when you want a low profile with a finished look rather than the full pan head sitting proud of the surface.

This is an electrical-department fastener, and a #12 x 1 inch stainless oval head Phillips is the size range used for cover plates, weatherproof covers, straps and brackets rather than for machine-threaded box holes. If you need to thread into an existing tapped hole in a box or device (typically 6-32 or 8-32), a #12 screw is the wrong fastener and you want a machine screw in the matching thread instead.

The JSTPO10 is 18-8 stainless, which is the common 300-series austenitic grade used for general corrosion resistance. That makes it a reasonable pick for exterior boxes, covers and damp-location work where a plain or zinc-plated screw would rust out. It is not a marine-grade 316 fastener, so in constant salt exposure you'd want to step up.

Each jar holds 100 screws. The pack type is a jar rather than a box, which is what MRO and electrical techs tend to keep on the truck or bench for repeat pulls of the same size.

Order it as Metallics JSTPO10. That designation covers the #12 x 1 inch oval head Phillips 18-8 stainless screw in the 100-piece jar, so there is a single model to specify with no finish or length option to pick.
