Metallics TP806SOC Screws 6-32 x 3/4 OV Span TR MS 18-8 (100 pcs)

The TP806SOC uses a spanner (snake-eye) tamper-resistant drive, which has two round holes in the head instead of a slot or cross recess. A standard flat, Phillips, or hex bit will not turn it. You need a spanner bit or spanner driver sized to the head, so order one with the screws if you don't already carry one.

18-8 is austenitic 300-series stainless, so these screws resist rust far better than plated steel and are a normal choice for damp, washdown, or exterior-but-sheltered work. For constant salt spray exposure, 316 stainless is the step up. 18-8 is also non-magnetic enough and galling-prone, so don't over-torque them into aluminum or stainless threads.

That's exactly what a 6-32 x 3/4 oval head spanner screw is for. The 6-32 thread matches the mounting threads used on wiring devices and plates, the oval head seats in a countersunk plate hole and sits nearly flush, and the spanner drive means only someone with the matching bit can back it out. Common on public restrooms, schools, transit, and corrections work.

Not quite the same. An oval head has the same 82-degree countersink underside as a flat head, so it drops into the same countersunk hole, but the top is domed rather than flat, leaving a slight raised crown above the surface. If you need a fully flush finish, specify a flat head instead of the TP806SOC oval.

One hundred pieces per pack, ordered as part number TP806SOC. That quantity suits a plate-swap on a floor of devices rather than a one-off repair, so plan the count against how many openings or plates you're securing.
