Metallics TP232SBC – Frequently Asked Questions
1) What driver do I need for the Metallics TP232SBC tamper resistant screw?
The TP232SBC is a star (six-lobe) drive with a center pin, so a standard Torx bit will not seat. You need a pin-in-star / pin-in-Torx security bit of the matching size. Plan on having those bits on the truck before you get to the job, because no common screwdriver or plain Torx driver will turn this head.
2) Is the Metallics TP232SBC a machine screw or a sheet metal screw?
It's a machine screw, 10-32 x 1-1/4 inch. The 10-32 is a straight machine thread, so it threads into a tapped hole or takes a 10-32 nut. It will not cut its own threads into sheet metal the way a self-tapping screw does, so the hole has to be tapped or you need a nut behind it.
3) Will a button head screw sit flush on an electrical cover plate?
No. The TP232SBC has a button head, which is a low domed head that sits on top of the surface rather than sinking into it. If you need the fastener flush with the face of the panel or plate, you want a flat head countersunk screw in a countersunk hole instead. Button head works where a slightly raised head is acceptable and it also gives a security head less purchase for pliers.
4) What is the Metallics tamper resistant 10-32 screw used for in electrical work?
Tamper resistant 10-32 x 1-1/4 inch machine screws like the TP232SBC are used where you don't want a cover coming off without the right bit: enclosure and panel covers, junction box lids, exterior fixtures, and anything in a public corridor, school, transit area, or multi-family common space. The pin-in-star head is the deterrent; the 1-1/4 inch length gives you enough reach for a cover plus a gasket or spacer into a tapped boss or nut.
5) What size hole or nut do I need for a 10-32 x 1-1/4 screw?
A 10-32 thread mates with a 10-32 tapped hole or a 10-32 machine screw nut. If you're tapping fresh material, the standard tap drill for 10-32 is a #21 drill. For a clearance hole where the screw passes through a cover and into a nut behind it, drill oversize so the shank passes freely. The 1-1/4 inch length is the usable grip, so total cover thickness plus any washer has to leave enough thread engaged.
6) How many screws come in a pack of Metallics TP232SBC?
100 pieces per pack. That's the quantity you get for the TP232SBC button head star pin machine screw, which is why it suits panel, enclosure, and fixture work where you're securing a run of covers at once rather than a single device.
