Metallics TP309SPC – Frequently Asked Questions
1) What does "PN Span TR" mean on the Metallics TP309SPC screw?
Pan head with a spanner tamper-resistant drive. A spanner head takes two small round holes instead of a slot or cross recess, so it needs a matching spanner (snake-eye) bit or driver. Standard Phillips and flat drivers will not turn it, which is the point: it keeps covers and plates from being removed with a common screwdriver.
2) Do I need a special bit to install Metallics TP309SPC tamper-resistant screws?
Yes. The spanner (two-hole) recess requires a spanner bit or spanner driver sized for a #8 head. No bit is included with the 100-piece box, so order the driver separately if your crew does not already carry one.
3) Are these 8-32 tamper-resistant screws suitable for electrical device and cover plate installation?
That is what they are for. 8-32 is the standard machine screw thread used on electrical boxes, device straps and cover plates, and the tamper-resistant spanner head is specified where a plate should not come off with a pocket screwdriver, such as public corridors, schools, transit areas and detention or multi-family common spaces. The 1-1/4 inch length gives extra reach where a plate sits over a mud ring or a thick finish build-up.
4) Is the Metallics TP309SPC a machine screw or a self-tapping screw?
Machine screw (MS). It has a uniform machine thread and no drill point, so it needs an existing tapped hole, a nut, or a threaded device strap. For attaching into sheet metal or drywall with no tapped hole, a machine screw is the wrong choice.
5) Are Metallics TP309SPC screws made in the USA?
Yes, the TP309SPC 8-32 x 1-1/4 pan head spanner screws are USA made, which is what buyers on public and federally funded work need when domestic-origin fasteners are called out on the submittal.
