Metallics 00PP02 Bit #2 x 1 PH-Pin TR Ins Bit

It drives tamper resistant pin-in-head Phillips screws, the kind with a solid pin standing up in the middle of the cross recess. The bit tip is a #2 Phillips with a hole bored down the center so it can pass over that pin. A standard #2 Phillips bit will not seat on these screws, and this bit will not sit properly in a plain Phillips head either, so keep it with the security fasteners it is meant for.

The 00PP02 is a 1 inch insert bit, the short stubby style with a 1/4 inch hex end. It is not a long power bit, so it drops into a bit holder, a magnetic bit tip holder, or the 1/4 inch hex chuck on an impact driver or screwgun. If you need reach down inside a box or past a recessed plate, you want the insert bit in an extension holder rather than the bit alone.

That is exactly the application. Pin-in-head Phillips in #2 is the common security head on electrical wallplates, device screws, cover plates, and enclosure hardware where you want to keep the public out of the box. The 00PP02 is an electrical supply line item, and the #2 tip size covers the great majority of that hardware. If the screw you are facing has a smaller or larger cross, measure the recess before ordering, since the tip size has to match the same way it does on a standard Phillips.

Order it as Metallics 00PP02. That is the manufacturer part number for the #2 x 1 inch pin-in-head Phillips tamper resistant insert bit, and it is the number to quote so you do not end up with a plain #2 Phillips or a Torx pin-in-head by mistake.
