Metallics TP209SBC – Frequently Asked Questions
1) What thread size and length is the Metallics TP209SBC tamper-resistant screw?
The TP209SBC is an 8-32 x 1-1/2 inch machine screw. That means a #8 diameter body with 32 threads per inch, so it mates with a tapped 8-32 hole or an 8-32 nut, and the 1-1/2 inch length is measured on the shank below the button head.
2) What driver do I need for a Metallics TP209SBC pin-in-star screw?
It takes a pin-in-star (pin-in-Torx) bit, not a standard Torx. The TP209SBC has a star recess with a solid post in the center, so a regular Torx driver will not seat on it. You need the matching tamper-resistant pin-in-star bit in the correct size for a #8 screw before you can install or remove these.
3) Why would I use a pin-in-star screw instead of a regular Phillips machine screw?
Security. A pin-in-star head resists removal with common bits, which is why these go into public-area cover plates, device plates, enclosures, fixtures and panels where you do not want tenants or passers-by opening things up. For a service point you expect to open regularly with ordinary tools, a standard slotted or Phillips 8-32 machine screw is the easier choice. The button head on the TP209SBC also sits low and rounded, so there is no sharp exposed corner.
4) Will the TP209SBC work in a 1/4-20 or #10 tapped hole?
No. The TP209SBC is cut 8-32 only, so it threads into #8-32 tapped holes and 8-32 nuts. A #10-32 or 1/4-20 hole needs a screw of that thread; forcing an 8-32 into a larger tapped hole leaves it loose and it will not hold a cover plate or enclosure lid.
5) Is the TP209SBC a machine screw or a self-tapping sheet metal screw?
It is a machine screw, so it needs an existing tapped hole or a nut behind the work. It will not cut its own thread in sheet metal the way a self-drilling or sheet metal screw does. If you are fastening into unthreaded steel, drill and tap to 8-32 or use a nut or threaded insert.
6) How many screws come in a box of Metallics TP209SBC?
100 pieces per box. For a property manager or electrical crew securing device plates or enclosure covers across a building, that is enough to cover a sizable batch of openings in one order, and keeping the whole fleet on the same pin-in-star head means one bit on the truck covers every one of them.
7) What is the Metallics part number for the 8-32 x 1-1/2 button head pin-in-star tamper screw?
TP209SBC is the Metallics part number, and it is the number to quote when ordering the 8-32 x 1-1/2 inch button head pin-in-star tamper-resistant machine screw in the 100-piece box.
