Metallics TP309SFC – Frequently Asked Questions
1) Do I need a special bit to install these spanner-head tamper-resistant screws?
Yes. The TP309SFC uses a spanner head, also called a snake-eye drive: two small round holes in the face of the screw rather than a slot, Phillips or hex recess. It cannot be driven with a standard screwdriver, which is the point of it. You need a spanner bit or spanner driver sized to that head, and no two-hole bit is universal, so match the bit to the pin spacing on the screw.
2) Will an 8-32 x 1-1/4 flat head screw work for mounting a tamper-resistant wall plate or device cover?
8-32 is the standard thread for electrical device and wall plate mounting hardware, and the TP309SFC is the tamper-resistant version of that screw in a 1-1/4 inch length, so it threads into the same device yokes and box ears. The 1-1/4 inch length is longer than a typical wall plate screw, so it suits deeper assemblies, spacers, or covers over recessed devices. For a flush plate on a flush-mounted device the extra length will bottom out or protrude behind, and a shorter 8-32 is the better pick.
3) Is the flat head on the TP309SFC countersunk or does it sit on the surface?
Flat head means a conical underside that sits flush when driven into a countersunk or chamfered hole. If the plate or cover you are fastening has a straight, uncountersunk hole, the head will stand proud instead of seating. Check the hole profile on your cover before ordering flat head rather than a pan or oval head.
4) Are these Metallics screws made in the USA?
Yes, the TP309SFC 8-32 x 1-1/4 tamper-resistant machine screw is USA made, which matters on public and institutional work where domestic-sourcing language appears in the spec.
5) How many screws come in a box of Metallics TP309SFC?
100 pieces per box, ordered as part number TP309SFC. For an MRO or multi-family buyer standardizing on tamper-resistant device hardware across a building, that is a single box covering 100 openings or covers rather than loose counts.
