Metallics TP210SBC Screws 8-32 x 2 Btn Star Pin TR MS 18-8 (100 pcs)

It takes a pin-in-star (pin-in-Torx) bit, not a standard Torx. The screw has a post in the center of the star recess, so a solid Torx bit will not seat. You need a tamper resistant star bit with a matching hole in the tip. A standard Torx, Phillips, or hex driver will not turn it, which is the point of the security head.

They are 18-8 stainless steel, the common 300 series austenitic grade used for general corrosion resistance. That makes them suitable for damp and exterior-exposed work such as outdoor fixture covers, enclosures, and public-area trim. For salt spray or coastal service, a 316 stainless fastener is the heavier-duty choice.

A pin-in-star tamper resistant screw like the TP210SBC stops casual removal of covers, plates, and enclosure doors in public or tenant-accessible areas. Nobody opens it with a pocket multi-tool. The trade-off is that your own crews need the matching security bit on the truck, so facilities that standardize on these usually buy the bit alongside the box of 100.

Yes, for a normal wall plate it is. A 2 inch 8-32 is a long machine screw meant for deep stack-ups, spacers, standoffs, or reaching through thick covers and gang boxes set back in the wall. If you are just fastening a plate to a device yoke, you want a short 8-32, not this one.

Order Metallics TP210SBC. That part number covers the 8-32 x 2 inch button head pin-in-star tamper resistant machine screw in 18-8 stainless, packaged 100 per box.
