Metallics TP135SFC – Frequently Asked Questions
1) What driver do I need for a hex pin tamper-resistant screw like the Metallics TP135SFC?
It takes a pin-in-hex (hex pin) security bit, not a standard Allen key. The recess is a hex socket with a pin in the center, so a plain hex wrench will not seat. Sized tamper bits or a security bit set covering pin-in-hex is what gets this driven and removed.
2) Why would I spec a tamper-resistant screw instead of a standard machine screw on electrical enclosures and covers?
The point of the TP135SFC is that it cannot be backed out with common tools. The pin-in-hex recess blocks a standard hex key, so covers, enclosures, wireways and public-area fixtures stay closed to anyone without the matching security bit. If the fastener is in a secured room or behind a locked panel, a standard 5/16-18 machine screw does the same mechanical job for less hassle at install.
3) Does the Metallics TP135SFC sit flush, or does the head stand above the surface?
It is a flat head screw, so it sits flush when driven into a countersunk hole. The mating hole needs the countersink to match; drop a flat head into a flat-faced hole and the head will stand proud and the fastener will not clamp properly.
4) How many screws come in a box of Metallics TP135SFC?
TP135SFC ships 100 pieces per box. For a facility standardizing on tamper-resistant cover screws across multiple panels, that is one box covering a lot of openings, and reordering under the single part number TP135SFC keeps the recess and thread consistent so one security bit works everywhere.
