Metallics TP145SBC – Frequently Asked Questions
1) What driver do I need for the TP145SBC button head pin screw?
A pin-in hex (tamper-resistant hex) key or bit in the matching size. The head is a button hex socket with a security pin in the center of the recess, so a standard hex key will not seat. You need a pin-in-hex bit with a hole drilled down the middle. Order the driver along with the screws if your techs do not already carry tamper bits.
2) Will a regular 1/2-13 hex key or Allen wrench work on these security screws?
No. The TP145SBC has a pin in the middle of the hex recess, which blocks a solid hex key from entering. That is the point of the fastener: it deters removal by anyone without the matching pin-in-hex driver. If you need a screw that any tech can back out with a standard Allen key, specify a plain socket or button head cap screw in 1/2-13 instead.
3) Is the TP145SBC a machine screw or a self-tapping screw?
Machine screw. The 1/2-13 designation is a standard coarse machine thread, so it threads into a tapped hole or takes a nut. It will not cut its own threads in sheet metal or form a thread in an undrilled hole. For the 3-1/2 inch length you will usually be through-bolting with a nut on the back side.
4) How many screws come in a pack of Metallics TP145SBC?
One hundred pieces per pack. That is a box quantity, which suits a contractor doing a run of enclosures, panel covers, or fixture mounts in one go rather than a one-off repair.
5) What is the Metallics part number to order these tamper-resistant button head screws?
Metallics TP145SBC. One model covers it, so there is no finish or length selection to make: the number brings a 1/2-13 x 3-1/2 inch pin-in-hex button head screw in a 100 piece pack.
