Metallics TP707SFC Screws 10-32 x 1-1/2 FH Star Pin TR MS 18 (100 pcs)

It takes a pin-in-torx (star pin) tamper-resistant bit, not a standard Torx. The TP707SFC has a pin in the center of the star recess, so a plain Torx bit will bottom out on the pin and won't seat. Order the matching pin-in-star bit with the screws if your crew doesn't already carry them.

Tamper-resistant is for anything the public can reach: device plates, enclosure covers, fixture trims, and panels in corridors, schools, transit areas, and multi-family common spaces. The star pin recess means it can't be backed out with a screwdriver, Phillips bit, or common Torx bit from a toolbox. A standard flat head 10-32 is the cheaper choice anywhere access control isn't the point.

Usually yes. At 1-1/2 inches the TP707SFC is a long machine screw, meant for stacking through spacers, deep trims, raised covers, extension rings, or mounting through an assembly into a tapped hole. Standard device plate screws run far shorter, so for a flush plate on a standard box you want a short 10-32, not this length.

Yes. The TP707SFC has a flat head, which seats flush only in a countersunk or chamfered hole. On a flat, un-countersunk cover the head will stand proud and won't pull down evenly, so pick a pan or truss head for that condition instead.

100 pieces per pack. That's the order unit, so a job needing a few hundred tamper-resistant 10-32 x 1-1/2 flat heads is ordered in multiples of 100 rather than by the individual screw.
