Metallics TP326SPC – Frequently Asked Questions
1) What thread size and length are the Metallics TP326SPC tamper-resistant screws?
The TP326SPC is a 6-32 x 3 inch machine screw, so it takes a standard 6-32 tapped hole or nut and gives you 3 inches of usable length. That length is what you reach for when the screw has to pass through a plaster ring, an extension, or thick trim before it picks up the threads in the box or device.
2) Do I need a special bit to install the Metallics TP326SPC screws?
Yes. These are spanner-head tamper-resistant screws, not Phillips or slotted, so they need a matching spanner (two-hole snake-eye) driver bit. Order the bit at the same time if your techs don't already carry one, because a standard driver will not engage the head.
3) Why use a tamper-resistant spanner screw instead of a regular 6-32 machine screw on a cover plate?
A plain 6-32 Phillips screw can be backed out by anyone with a pocket screwdriver. The spanner head on the TP326SPC needs a dedicated two-hole bit, which is why it gets specified on wall plates, device covers, and junction box covers in schools, transit areas, correctional facilities, and public restrooms where opened covers are a recurring problem. Thread and length stay the same at 6-32 x 3, so nothing about the box prep changes.
4) What head style are the TP326SPC screws, and will the head sit flush?
Pan head. A pan head sits on top of the surface with a low rounded crown, it does not countersink flush the way a flat head would. If your plate or cover is counterbored for a flush flat-head screw, a pan head is the wrong profile for it.
5) How many screws come in a pack of Metallics TP326SPC?
100 pieces per pack. For MRO and facility stock that is enough to standardize tamper-resistant covers across a floor or a building section on one order, so every opening takes the same bit.
6) Are the Metallics TP326SPC spanner screws made in the USA?
Yes, the TP326SPC is USA made, which matters when a job carries a domestic-sourcing requirement on fasteners for government, transit, or federally funded work.
