Metallics TP108SBC – Frequently Asked Questions
1) What thread size and length is the Metallics TP108SBC screw?
The TP108SBC is an 8-32 x 1-1/4 inch machine screw. The 8-32 is a unified machine screw thread, so it mates with a tapped 8-32 hole or an 8-32 nut, not with wood or sheet metal. The 1-1/4 inch length gives you grip through a cover plate or bracket plus thread engagement behind it.
2) What driver do I need for a hex pin tamper-resistant screw like the TP108SBC?
It takes a pin-in-hex (hex socket with a center pin) security driver sized to the socket. A standard hex key will not seat because the pin in the middle of the recess blocks it, which is the whole point of the design. Stock the matching pin-hex bit before you head out, or the fasteners stay in the box.
3) Why would I use a tamper-resistant screw instead of a standard machine screw on electrical covers?
Tamper-resistant pin hex screws like the Metallics TP108SBC are used where you do not want the public opening the enclosure: panel covers, device plates, and boxes in corridors, schools, transit areas, and multi-family common spaces. A standard slotted or Phillips machine screw of the same 8-32 x 1-1/4 size does the same mechanical job, but anybody with a pocket screwdriver can back it out. Use the standard screw in locked rooms and the pin hex where the cover is exposed.
4) Is the TP108SBC button head screw going to sit flush, or does the head stand proud?
It is a button head, so the head sits on top of the surface with a low domed profile, not down inside a countersink. If your plate or cover is countersunk for a flat head, this screw will not pull in flush and will leave a raised crown. For a flush finish you need a flat head screw in the same 8-32 x 1-1/4 size instead.
5) How many Metallics TP108SBC screws come in a pack?
They ship 100 pieces to the box under part number TP108SBC. That is a practical count for an MRO or property maintenance crew standardizing one tamper-resistant fastener across a building, since you want a single driver size on the truck rather than a mix.
