Metallics TP102SFC Screws 6-32 x 1 FH Hx Pin TR MS 18-8 (100 pcs)

It takes a pin-in hex (tamper resistant hex) bit, not a standard Allen key. The head has a center pin that blocks a solid hex driver, so you need a security hex bit of the matching size to drive or remove it. Order the bit with the screws if your techs don't already carry a tamper bit set.

That's the usual reason to buy them. Because the thread is 6-32, the same size as standard device and plate screws, they thread into the same tapped mounting holes in a device yoke or box ear. The difference is the pin-in hex head, so a plate can't be pulled with a screwdriver. Check screw length though: at 1 inch these are longer than the short screws that ship with most devices, so they suit deeper stacks such as plates over extension rings or thick mounting brackets.

They're 18-8 stainless, which is the austenitic 300 series grade used for general corrosion resistance. That makes them suitable for damp or exterior-rated enclosures and coastal-adjacent work where a plated steel screw would rust and seize. 18-8 is non-magnetic as supplied and softer than hardened steel, so don't overtorque them in a tapped hole.

Yes, it's a flat head, so it's made to seat in a countersunk hole and finish flush with the surface. If your plate or enclosure lid has a straight-walled clearance hole rather than a countersink, the head will stand proud and you'd want a pan or truss head screw instead.

100 pieces per box. For a facility standardizing on tamper resistant hardware across panels, junction boxes, or public-area device plates, that covers roughly 50 two-screw plates, so figure your box count off device count rather than door or room count.

Metallics catalogs it as TP102SFC. That single model covers the 6-32 x 1 inch flat head pin-in-hex machine screw in 18-8 stainless, sold 100 to a box.
