Metallics SPT812 Screws 8-32 X 1-1/4 Ov Tr Span Switch SS (Clam 50)

Yes. The SPT812 is an 8-32 machine screw, which is the standard thread used on wiring device mounting straps and wall plates in North America. Thread pitch is 32 per inch on a #8 body, and the 1-1/4 inch length gives extra reach where the device sits deep in the box or behind a thick plate or spacer.

Nothing extra to buy. The SPT812 uses a spanner (two-hole) drive, and the clamshell ships with the 00SP6B spanner insert bit, so one crew kit covers the install. A standard slotted or Phillips driver will not engage the head, which is the point: once the plate is on, anyone without a spanner bit is not taking it off.

For a plain plate on a flush-mounted device, 1-1/4 inches is longer than needed and the excess thread will bottom in the strap or run past it into the box. The length pays off when you're going through a thick or weatherproof cover, a plate spacer, a stacked gang arrangement, or into a device that's recessed behind finished surface. For a standard flush install, a shorter tamper-resistant plate screw is the better call; Metallics offers other sizes on request.

They're 18-8 stainless steel, so corrosion resistance is far better than a plated steel plate screw. That suits locker rooms, kitchens, pool areas, exterior-adjacent and washdown locations where a plain steel screw rusts and streaks the plate.

The SPT812 is sold as a 50-piece clamshell, with a minimum order of 50 each. That's enough to secure roughly 25 to 50 single-gang plates depending on how many screws each plate takes, and the spanner bit comes in the same pack.

Yes, the SPT812 is flagged compliant for both ARRA and Buy American requirements, which is what a public-sector or federally funded project submittal usually asks for on fasteners.

Anywhere a plate gets pulled off that shouldn't be: school and dorm corridors, detention and behavioral health rooms, public restrooms, transit stations, apartment common areas and vacant-unit turns. Metallics lists the application as electrical, plumbing, heating and air conditioning work. The spanner head means a resident or passerby with a pocket screwdriver can't open the device.

Oval/pan head, so it sits slightly proud of the plate with a rounded profile rather than countersunk flush. If your existing plates are machined for a flat countersunk screw head, the look will differ from what's on the wall now.
