Metallics TP407SRC Screws 8-32 x 3/4 RH 1way TR MS USA 1 (100 pcs)

Not with a normal driver. A one-way head like the one on the TP407SRC has ramped slots that let a flat blade drive the screw in but cam out when you try to back it out, which is the whole point for cover plates, enclosures and fixtures in public or tenant-accessible areas. If you expect to service the assembly, use a standard slotted or Phillips 8-32 machine screw instead and keep the one-way screws for the openings you want left alone.

8-32 is the standard thread for electrical device mounting and cover plate screws in North America, so the TP407SRC threads into the 8-32 tapped holes in receptacle and switch straps, device rings and most plate hardware. The 3/4 inch length is longer than a typical plate screw, so it suits deeper stack-ups such as plates over mud rings or spacers rather than a plate sitting flush on the device.

Yes, the TP407SRC 8-32 x 3/4 one-way screw is a USA-made part, which matters on government, school and other public jobs carrying a domestic-origin requirement on fasteners.

Order Metallics TP407SRC. That number covers the 8-32 x 3/4 round head one-way tamper resistant machine screw in the 100 piece pack, and it is the only configuration under that number, so there is no length or head option to specify.

Each pack is 100 pieces of the 8-32 x 3/4 one-way round head machine screw. For a crew securing cover plates or device enclosures across a building, that is the quantity to figure against your plate count, since a single fixture typically takes two.
