Metallics TP133SBC – Frequently Asked Questions
1) Will the Metallics TP133SBC thread into sheet metal or a wood frame?
No. It is a machine screw, not a self tapping or wood screw. The 5/16-18 thread runs the length of a straight shank and needs either a pre-tapped 5/16-18 hole or a nut on the back side. For attaching into unthreaded sheet metal you would need to tap the hole first or add a nut, insert or weld nut.
2) Do I need a special bit to install a hex pin tamper resistant screw like the TP133SBC?
Yes. The hex pin head has a solid post in the center of the hex recess, so a standard 5/16 hex key or Allen bit will not seat. You need a pin-in-hex (hex pin) driver bit or key of the matching size. Crews installing these on signage, panels, enclosures or public fixtures should carry the bit on the truck, since nothing in a standard hex set will drive them.
3) Why use a button head instead of a flat head screw on an exposed panel?
The button head on the TP133SBC sits on top of the surface with a low rounded crown, so it needs no countersink in the material. A flat head would require a chamfered or countersunk hole to sit flush. For thin panels, enclosure covers and sign faces that cannot be countersunk, the button head is the one that works, and the rounded profile gives a pry bar less to catch.
4) How much grip length do I get from a 2 inch tamper resistant screw?
On a button head screw the 2 inch dimension is measured from under the head, so the full 2 inches is usable through your material plus nut engagement. Subtract your total material stack to see what is left for the nut; for a 5/16-18 nut you want at least about a quarter inch of thread protruding past it.
5) Is the Metallics TP133SBC sold individually or by the box?
It comes 100 pieces per box under part number TP133SBC. That quantity suits an MRO or facilities crew standardizing on one tamper resistant fastener across multiple openings, panels or fixtures rather than buying loose pieces per job.
