Metallics TP611SBC – Frequently Asked Questions
1) What driver bit do I need for the Metallics TP611SBC tamper-resistant screw?
The TP611SBC is a star pin drive (pin-in-Torx) screw, so a standard Torx bit will not seat. You need a pin-in-star bit, which has a hole bored down the center to clear the pin in the middle of the recess. Sizing the bit to a #10 star pin head is the part people get wrong, so put the bit in the kit before the screws go on the job.
2) Will a regular screwdriver or Torx bit back out a star pin screw like the TP611SBC?
No, and that is the point of it. The pin in the middle of the star recess blocks a plain Torx bit, a flat blade, and a Phillips, so the fastener cannot be removed without the matching pin-in-star bit. That is why these get used on enclosure covers, device plates, and public-access panels where you do not want anyone with a pocket screwdriver opening it up.
3) Is the TP611SBC a sheet metal screw or a machine screw?
Sheet metal screw. It takes a self-threading sheet metal thread, so it bites directly into a drilled or punched hole in sheet steel or an enclosure flange rather than threading into a tapped machine-screw hole. If the hole in your box or plate is already tapped 10-32, this is the wrong fastener and you want a tamper-resistant machine screw instead.
4) Is a 1-1/4 inch screw too long for fastening a cover plate to a sheet metal enclosure?
At 1-1/4 inches of length under a button head, there is enough thread to pass through a cover and still grip the flange, but it will protrude behind thin sheet. On enclosures with clearance behind the flange that is a non-issue; where a device, conductor, or wall surface sits tight behind the fastening point, step down to a shorter #10 tamper-resistant screw instead of trimming this one.
5) What part number do I order for Metallics #10 x 1-1/4 button head star pin tamper-resistant screws?
Order Metallics TP611SBC. That number covers the #10 x 1-1/4 button head star pin tamper-resistant sheet metal screw in the 100-piece pack, and it is the full manufacturer part number to quote on a purchase order.
