Metallics TP120SBC – Frequently Asked Questions
1) What driver do I need for a hex pin tamper-resistant screw like the TP120SBC?
Hex pin head, so a standard hex key will not turn it. The TP120SBC has a pin in the center of the hex socket, which requires a pin-in-hex (also called hex pin or pin-in-socket) security bit sized for a 1/4-20 button head screw. Order the matching bits with the screws if your crew does not already carry them, otherwise the fasteners cannot be installed or removed.
2) Is the TP120SBC a machine screw for a tapped hole, or a self-tapping screw for sheet metal?
It is a machine screw. The 1/4-20 designation is a unified machine thread, which means it goes into a 1/4-20 tapped hole, a weld nut, or a nut and washer, not into undrilled sheet metal. For enclosure covers, panel boards and trim plates that are already tapped 1/4-20, it drops straight in.
3) Why use a button head tamper-resistant screw on electrical enclosures and panel covers?
Two reasons. The button head sits low and rounded, so there is no sharp corner proud of a cover plate or trim, and the hex pin socket stops anyone opening the enclosure with a common hex key or screwdriver. That combination is why these get specified on public-access panels, transit and institutional installs where the cover has to stay on. The TP120SBC covers the common 1/4-20 cover-screw size at a 1-1/2 inch length for thicker stack-ups.
4) What is the Metallics part number to order for a 1/4-20 x 1-1/2 button head pin hex security screw?
Metallics TP120SBC. That single MPN covers the 1/4-20 x 1-1/2 inch button head, pin-in-hex tamper-resistant machine screw in the 100 piece pack, so there is no second option code to specify.
5) How many Metallics TP120SBC screws come in a box?
One hundred pieces per box. For a facility standardizing on tamper-resistant 1/4-20 hardware, that is enough to cover a sizeable run of enclosure covers from a single order rather than mixing head styles across openings.
