Metallics TP336SPC Screws 10-32 x 1-1/2 PN Span TR MS US (100 pcs)

The TP336SPC uses a spanner (snake eye) drive, which takes a two pin spanner bit, not a Phillips or a square bit. Two round holes in the head face the driver and nothing else engages them, which is the point: once it is installed, nobody without the matching bit is taking it out. Buy the spanner bit at the same time if your crew does not already carry one.

For public restrooms, corridors and other high traffic areas where plates get picked at, a spanner head screw is the usual answer, and the TP336SPC is that screw in 10-32 thread. The catch is thread size and length: device and plate screws on wiring devices are 6-32, so confirm the tapped hole you are driving into is 10-32 before you standardize on this one. At 1-1/2 inches it suits deeper assemblies rather than a flush plate on a standard box.

Pan head, so it sits on top of the surface rather than sinking into it. There is no countersink taper, which means you do not need a countersunk hole, but you do need clearance for the head to stand proud. If you need a flush finish in a countersunk plate, a pan head is the wrong profile.

100 screws per box, ordered under part number TP336SPC. That quantity suits a crew standardizing tamper resistant hardware across a run of openings or fixtures rather than a single repair, since spanner screws are worth buying in bulk once you already own the bit.
