Metallics TP206SFC Screws 8-32 x 3/4 FH Star Pin TR MS 18-8 (100 pcs)

It takes a pin-in-star (pin-in-Torx) bit. The TP206SFC is a star pin tamper resistant machine screw, so a standard Torx bit will not seat, the center post in the recess blocks it. You need the matching pin-in-Torx driver for the size.

Yes, it is a flat head screw, so it seats flush in a countersunk or chamfered hole. If your plate or enclosure has a straight drilled hole with no countersink, the head will stand proud, use a pan or truss head style instead.

They are 18-8 stainless steel, the common 300-series austenitic grade, which gives good general corrosion resistance for exterior and damp locations. For coastal salt exposure or chemical environments a 316 stainless fastener is the better choice.

Tamper resistant pin-in-star screws keep the public out of covers, plates, and enclosures in schools, transit areas, detention, healthcare, and other open facilities. Because the driver is uncommon, a passerby with a pocket screwdriver cannot open the device. The tradeoff is that your own crews must carry the pin-in-Torx bit, so standardizing one tamper style across a building is worth doing.

One box holds 100 pieces of the 8-32 x 3/4 star pin tamper resistant screw. That is a practical quantity for securing a run of plates, covers, or enclosures where you want all of them on the same security bit.
