Metallics TP344SFC – Frequently Asked Questions
1) What kind of driver do I need for the TP344SFC tamper-resistant screw?
It takes a spanner bit, also called a snake eye. The head has two round holes set either side of center, and a standard flat, Phillips or hex driver will not engage it at all. Order the matching 1/4-20 spanner bit along with the screws if your crew does not already carry one, otherwise the fasteners cannot be installed or removed.
2) Can I use the TP344SFC to screw directly into wood or drywall?
No. This is a machine screw, so it needs a mating 1/4-20 tapped hole, nut or threaded insert. For wood framing or drywall you want a tapping or self-drilling tamper-resistant screw instead. If the existing hole in your panel is unthreaded, either tap it to 1/4-20 or back the screw with a nut.
3) Will a flat head spanner screw sit flush in my cover plate?
Yes, provided the hole is countersunk. The TP344SFC uses a flat head, which is the conical style that seats down into a chamfered or countersunk hole and finishes level with the surface. On a plain punched hole with no countersink the head will stand proud. Stamped steel plates and enclosure covers that are already dimpled for flat head screws are the usual match.
4) Are these Metallics tamper-resistant screws made in the USA?
Yes. The TP344SFC 1/4-20 spanner machine screw is USA made, which matters on government, institutional and publicly funded jobs carrying domestic sourcing requirements on fasteners.
5) Why specify a spanner screw instead of a standard Phillips on electrical covers?
Deterrence. On junction box covers, panel fronts, transformer enclosures and anything in a public corridor or tenant space, a Phillips head invites anyone with a pocket screwdriver. The spanner drive on the TP344SFC needs a dedicated two-pin bit, so the cover stays on until someone with the right tool opens it. The tradeoff is that your own techs must carry the bit too.
6) How many screws come in a pack of Metallics TP344SFC?
One hundred pieces per pack. That quantity suits a property manager or facilities crew standardizing tamper-resistant hardware across multiple panels, cover plates or enclosures in one building rather than buying for a single opening.
