Metallics TP425SRC Screws 10-32 x 3/4 RH 1way TR MS USA (100 pcs)

Not with a normal screwdriver. A one-way head drives in clockwise and the ramped slot lets the bit slip when you try to back it out, which is the whole point of using it on covers you do not want opened. If you expect to service the box or plate routinely, use a standard slotted or combination head 10-32 machine screw instead and save the one-way for the covers you want to stay shut.

10-32 is the standard thread for electrical box and cover plate screws, so the TP425SRC threads into those tapped holes. Watch the length: at 3/4 inch it is longer than the short screws typically shipped with a plate, so it is meant for thicker assemblies or deeper threaded bosses. On a thin plate over a shallow tapped hole, a 3/4 inch screw can bottom out before it clamps.

A standard flat blade screwdriver drives them. The one-way head takes an ordinary slotted bit going in; the resistance only shows up on the way out. No proprietary bit or special driver is needed to install the TP425SRC, which is part of why it gets specified over security-bit heads on high-volume cover work.

Each pack holds 100 pieces of the 10-32 x 3/4 one-way round head machine screw, which is why it suits a property manager or MRO buyer securing a run of covers or plates across a building rather than a single fix.

Yes. The TP425SRC 10-32 x 3/4 one-way machine screw is USA made, which matters on government, institutional, and other domestic-preference jobs where the submittal has to show country of origin.
