Metallics TP232SFC Screws 10-32 x 1 FH Star Pin TR MS 18-8 (100 pcs)

The TP232SFC is a star pin drive screw, so it takes a pin-in-Torx bit, not a standard Torx. The center pin in the recess blocks a plain Torx or hex driver, which is the point of a tamper-resistant fastener. Stock the matching pin-drive bit before you head to the job or the screws will not go in.

Yes. The TP232SFC has a flat head, which is the countersunk profile that seats flush in a chamfered hole. If your plate or enclosure has flat, non-countersunk holes, a flat head will stand proud and you want a pan or truss head instead.

They are 18-8 stainless steel, the austenitic grade used where plated carbon steel would rust, so they hold up in damp interiors and general exterior use. For salt spray or coastal exposure, 316 stainless is the step up. 18-8 is also non-magnetic in the annealed condition, which matters on some instrument and low-voltage work.

Tamper resistance is the whole reason to specify the TP232SFC over a plain 10-32 slotted or Phillips screw. The pin in the star recess means nobody opens the plate or enclosure with a screwdriver out of a glovebox, which is what you want in schools, transit areas, common corridors, detention, and any public-facing device. Functionally it is the same 10-32 x 1 inch flat head machine screw otherwise, so it drops into the same tapped hole.

Each pack holds 100 pieces, all one size at 10-32 x 1 inch. That quantity suits a property manager or MRO buyer standardizing tamper-resistant cover plates across a run of units rather than a single-device repair.
