Metallics TP207SFC Screws 8-32 x 1 FH Star Pin TR MS 18-8 (100 pcs)

The TP207SFC is a 8-32 x 1 inch machine screw, so it's a #8 diameter with 32 threads per inch and a 1 inch length. Machine thread, not sheet metal thread, so it mates with a tapped hole or a 8-32 nut.

It takes a pin-in-star (pin-in-Torx) security bit, not a standard Torx. The TP207SFC head has a center pin in the star recess, so a plain Torx driver will bottom out on the pin and won't seat. You'll need the matching pin-in-star bit on the driver.

They're 18-8 stainless, the common 300 series austenitic grade, so they resist rust in damp and exterior-exposed locations far better than plated carbon steel. 18-8 is also non-magnetic in the annealed state, which matters if you're fastening near sensitive equipment.

The TP207SFC has a flat head (FH), which is countersunk, so it seats flush in a chamfered or countersunk hole. If your plate or enclosure has a straight drilled hole with no countersink, the head will stand proud and you'd want a pan or truss head instead.

Each pack is 100 pieces of the 8-32 x 1 inch tamper-resistant flat head screw, ordered under part number TP207SFC. That's a practical quantity for a building full of device plates or enclosure covers where you want one bit and one screw across the whole facility.

Security screws like the TP207SFC keep cover plates and enclosure covers from being opened with a bit anyone carries. In schools, transit areas, detention, public restrooms and common areas, that stops casual access to wiring and devices. The pin-in-star recess means a standard Torx or driver bit won't turn it, so only maintenance with the correct bit gets in.
