Metallics TP101SBC Screws 6-32 x 3/4 Btn Hx Pin TR MS 18 (100 pcs)

The TP101SBC takes a pin-in-hex (hex-pin) driver, not a standard hex key. The button head is machined with a center pin inside the hex socket, so a plain Allen wrench will not seat. You need the matching pin-in-hex bit or key for a 6-32 screw before you start the install.

It's a machine screw, 6-32 x 3/4 inch. That means it needs a tapped hole or a 6-32 nut to thread into. It will not cut its own thread in sheet metal or an untapped enclosure, so drill and tap first or pair it with a 6-32 nut.

18-8 stainless steel. That's the common 300 series austenitic stainless used for fasteners, so these hold up in damp interior and sheltered exterior electrical work far better than plain or zinc-plated steel. For heavy salt exposure, a 316 fastener is the step up.

Three quarters of an inch is longer than the 1/2 inch screw typically supplied with a wall plate, so it's aimed at thicker covers, stacked gaskets, or a deeper standoff where the shorter screw won't reach the tapped boss. If you only have thin sheet metal and a tapped strap behind it, the extra length has to have somewhere to go, or it will bottom out past the thread.

No. A button head is a low, domed head that sits on top of the material, not a countersunk one. If your cover is countersunk and you need the head flush, a button head is the wrong profile. Where you want the head proud and smooth, so there's little for a pry tool or a hand to grab, it's the right pick.

The point is deterrence in spaces the public can reach, lobbies, corridors, restrooms, schools, transit areas. A Phillips cover screw comes off with any driver in a pocket; the pin in the center of the hex socket on the TP101SBC blocks a standard hex key and requires the matching security bit. It's a tamper deterrent, not a lock, so pair it with proper enclosure security where the hazard warrants.

100 pieces per box. For a property manager or MRO buyer standardizing tamper-resistant cover screws across panels, device plates, or fixture housings, that is enough to do a run of openings off one box rather than ordering per door.

Order Metallics TP101SBC. That's the manufacturer part number for the 6-32 x 3/4 inch button head hex-pin tamper-resistant machine screw in 18-8 stainless, boxed 100 pieces.
