Metallics TP212SBC – Frequently Asked Questions
1) What size and thread is the Metallics TP212SBC tamper-resistant screw?
The TP212SBC is a 10-24 x 3/4 inch machine screw. The 10-24 designation means a #10 diameter with 24 threads per inch, so it mates with a tapped 10-24 hole or a 10-24 nut, not a self-tapping sheet metal application. Grip length is 3/4 inch under the head.
2) What driver do I need for a pin-in star (pin Torx) screw like the Metallics TP212SBC?
A standard Torx bit will not work. The TP212SBC uses a button head star drive with a pin in the center of the recess, so it takes a pin-in-star (Torx-with-hole) security bit sized to the recess. Order the bits at the same time as the screws if your crew does not already carry a security bit set, otherwise the fasteners cannot be installed or removed on site.
3) Why would I use a tamper-resistant screw instead of a standard machine screw on an electrical enclosure?
Tamper-resistant fasteners like the Metallics TP212SBC are used where you do not want the public, tenants, or unauthorized staff opening a cover: panel and box covers, device plates, exterior enclosures, transit and school facilities. The pin in the star recess blocks a common Torx bit, so only someone carrying the matching security bit can back the screw out. Functionally it still torques down like any 10-24 machine screw.
4) Does the button head on the TP212SBC sit flush, or does it stand proud of the cover?
A button head stands proud. The TP212SBC has a low domed button head that bears on the surface of the cover rather than sinking into it, so it does not need a countersunk hole, but it will leave a rounded head above the panel face. If you need the fastener flush with the surface, a button head is the wrong profile and you want a countersunk flat head instead.
5) How many screws come in a pack of Metallics TP212SBC?
They ship 100 pieces per pack. For an MRO or facilities buyer standardizing covers across a building, that is typically enough for several dozen enclosures, and buying one keyway-equivalent drive across the site means one security bit covers every cover plate.
6) What is the correct Metallics part number to reorder these tamper-proof 10-24 screws?
Order Metallics part number TP212SBC. That designation covers the 10-24 x 3/4 button head pin-star tamper-resistant machine screw in the 100 piece pack.
