Metallics TP423SRC – Frequently Asked Questions
1) Can a one-way tamper resistant screw like the Metallics TP423SRC be removed once installed?
Not with a standard driver, which is the point of it. A one-way (TR) head drives clockwise with a flat blade and cams out when you try to back it off, so it is used where you do not want the fastener taken out with common tools, on covers, signage, grilles and panel plates. If you expect to service the assembly, pick a conventional slotted or Phillips machine screw instead.
2) Is the TP423SRC a machine screw for tapped holes or a self-tapping sheet metal screw?
It is a machine screw (MS) with a uniform 1/4-20 machine thread, so it needs a tapped 1/4-20 hole or a nut behind the work. It will not form its own thread in sheet metal. For a clean through-hole in thin material, pair it with a 1/4-20 nut, Tinnerman clip or threaded insert.
3) What head style does the Metallics 1/4-20 x 2 one-way screw have, and does it sit flush?
Round head (RH). The head crowns above the surface rather than sitting flush, so it does not need a countersunk hole. If you need a flush face, a flat-head countersunk one-way screw is the one to look for instead.
4) How do I order the Metallics one-way round head screw, and how many come in a pack?
Order by part number TP423SRC. It ships 100 pieces to the pack, all one size, 1/4-20 x 2 inch round head one-way. There is a single configuration, so there is no finish or length to specify on the order.
5) Are Metallics TP423SRC screws made in the USA?
Yes, the TP423SRC 1/4-20 x 2 one-way screw is USA made, which matters on government, institutional and federally funded work where domestic sourcing is written into the spec.
