Metallics TP142SBC – Frequently Asked Questions
1) What thread size and length are the Metallics TP142SBC tamper-resistant screws?
The TP142SBC is a 1/2-13 x 2 inch screw. The 1/2-13 callout is the standard coarse (UNC) machine screw thread for 1/2 inch diameter, so it threads into a 1/2-13 tapped hole or takes a standard 1/2-13 nut. Overall length under the button head is 2 inches, so figure your total clamped thickness plus enough thread engagement into the nut or tapped part.
2) Do I need a special bit to drive a pin-in-hex button head screw like the TP142SBC?
Yes. The TP142SBC uses a pin-in-hex (tamper-resistant) button head socket, which has a pin in the center of the hex recess. A standard hex key or Allen bit will not seat in it, and that is the point of the fastener. You need a pin-in-hex driver sized to the recess. If your crew does not already carry pin-in-hex bits, order them with the screws or the hardware cannot be installed or removed.
3) Will a 1/2-13 x 2 security screw work in an existing 1/2 inch bolt hole on electrical enclosure hardware?
If the existing fastener is a 1/2-13 thread and the hole is drilled for 1/2 inch, yes, the TP142SBC drops into the same hole and mates with the same 1/2-13 nut or tapped boss. Two things to check against what you are pulling out: the grip length (this one is 2 inches overall, so it will not reach through a thicker stack than the original) and the head. A button head is lower and smaller in diameter than a hex head, so if the original fastener's head was carrying a washer or spanning an oversized hole, add a flat washer to suit.
4) Is the Metallics TP142SBC sold individually or by the box?
It ships as a 100 piece pack. One order of TP142SBC gets you 100 of the 1/2-13 x 2 inch button head pin-in-hex screws, which is how security fasteners are typically bought for a multi-opening or multi-fixture job rather than a single repair.
5) Why choose a button head pin-in-hex screw instead of a standard hex head bolt?
Two reasons, and both are about exposure. The button head sits low and rounded, so there is little to grab with a wrench or pliers and less to catch on in a corridor or public space. The pin-in-hex recess defeats common hand tools, so the fastener is not backed out with a pocket multi-tool. A standard hex head bolt is faster to install with ordinary tools and is the better choice where the fastener is not reachable by the public. For enclosures, grates, signage, benches, and fixture mounting in public areas, the pin-in-hex version like the TP142SBC is what gets specified.
