Metallics TP129SBC – Frequently Asked Questions
1) What driver do I need for a button head hex pin screw like the Metallics TP129SBC?
It takes a pin-in-hex (hex-pin) tamper resistant bit, not a standard Allen key. The TP129SBC has a button head with a hex socket that has a pin in the center, so a plain hex wrench bottoms out on the pin and will not seat. You need the matching pin-in-hex driver bit sized to the socket before you can install or remove these.
2) Will a regular Allen wrench or Torx bit remove these Metallics TP129SBC screws?
No. The TP129SBC uses a hex socket with a center pin, so a standard hex key cannot drop in and a Torx bit will not engage at all. If you are maintaining an installation already fitted with these, stock the pin-in-hex bits with the fasteners or the covers come off nowhere.
3) What is the Metallics tamper resistant machine screw part number for 5/16-18 x 3/4?
TP129SBC is the Metallics part number for the 5/16-18 x 3/4 inch button head hex pin tamper resistant machine screw, sold 100 to a pack. Order by that MPN to get the button head with the pinned hex socket rather than a standard socket cap.
4) Can I use these for securing electrical enclosure covers in a public area?
That is the application this fastener is built for. The pinned hex socket on the TP129SBC means a passerby with common hand tools cannot back the screw out, which is why tamper resistant machine screws get specified on panel covers, junction boxes, and fixture housings in corridors, transit areas, and schools. The threads are 5/16-18, so the cover or enclosure has to be tapped or nutted for that size.
5) How many screws come in a pack of Metallics TP129SBC?
100 pieces per pack. One order quantity covers a run of enclosure covers, panel faces, or fixture housings without reordering mid-job, which is the usual reason this fastener gets bought by the box rather than loose.
