Metallics TP140SBC – Frequently Asked Questions
1) What thread size and length are the Metallics TP140SBC tamper-resistant screws?
The TP140SBC is a 1/2-13 x 1 inch screw, so it's a 1/2 inch diameter machine screw thread with 13 threads per inch and a 1 inch length. The 1/2-13 thread is a standard UNC coarse pitch, so it mates with 1/2-13 nuts and tapped 1/2-13 holes. Sold 100 pieces to the box.
2) What kind of driver do I need for a button head hex pin screw like the TP140SBC?
A pin-in hex (hex pin) bit, not a plain Allen key. The TP140SBC has a hex socket with a solid pin standing in the center, so a standard hex wrench will not seat. You need the matching pin-in-hex security bit sized to the socket. That pin is the whole point of the fastener, it keeps anyone without the special bit from backing it out.
3) Is the TP140SBC screw head flush or raised once installed?
Raised. A button head sits on top of the surface with a low domed crown and a flat bearing underside, so it does not need a countersunk hole, just a through hole or a tapped 1/2-13 hole. If you need the fastener to finish flush with the material face, a button head is the wrong profile and you want a flat (countersunk) tamper-resistant head instead.
4) What part number do I give my supplier for Metallics 1/2-13 x 1 button head pin hex security screws?
Order by Metallics MPN TP140SBC. That designation covers the 1/2-13 x 1 inch button head pin-in-hex tamper-resistant screw in a 100 piece box, and giving the full number avoids getting a different length or a plain hex socket version.
5) How many Metallics TP140SBC screws come in a box, and should I order spares?
Each box of TP140SBC holds 100 pieces. Order spares if the install is permanent security work, tamper-resistant screws with a center pin do not always survive removal cleanly, and the pin-in-hex bit itself wears with repeated high-torque driving on a 1/2 inch fastener.
