Metallics TP412SRC – Frequently Asked Questions
1) What size screw is the Metallics TP412SRC, and what does 10-24 mean?
The TP412SRC is a #10-24 x 1/2 inch machine screw, sold 100 to a box. The 10-24 is the thread callout: a #10 diameter body with 24 threads per inch, which is the standard coarse machine screw thread in that diameter. The 1/2 inch is the length under the head. Because it is a machine screw and not a self-tapping screw, it needs a tapped 10-24 hole or a matching nut on the back side.
2) Is the TP412SRC a tamper resistant screw, and can it be removed once installed?
It is a one-way tamper resistant screw. The head drives in with an ordinary flat blade screwdriver, but the ramped slot cams the blade out in the reverse direction, so it cannot be backed out with a standard driver. Plan on it being a permanent fastener unless you have an extraction tool. If you expect to service the assembly, use a conventional slotted or Phillips 10-24 machine screw instead.
3) What head style does the Metallics TP412SRC one-way screw have, and will it sit flush?
Round head. It seats on top of the surface rather than sinking into it, so it does not need a countersunk hole and it will stand proud of the plate or cover you are fastening. If your part is countersunk and you need the head flush, a round head one-way screw is the wrong choice for that hole.
4) Will 10-24 x 1/2 one-way screws work for securing electrical covers and device plates?
That is the usual application. The 10-24 thread is the common machine screw size for electrical enclosure covers, box ears and plate hardware, and the one-way head keeps the cover from being opened casually in public restrooms, corridors, schools and transit spaces. Confirm the tapped hole in your enclosure is 10-24 and that 1/2 inch of length gives you enough thread engagement through the cover thickness.
5) How many Metallics TP412SRC screws come in a box?
Each box holds 100 screws, which makes it a practical stocking item for an MRO crib or a truck when you are standardizing tamper resistant fasteners across a building. Order quantity is counted in boxes of 100, not individual pieces.
6) Are Metallics TP412SRC tamper proof screws made in the USA?
Yes, the TP412SRC one-way round head machine screw is USA made, which matters on public works and federal jobs carrying domestic sourcing requirements. The part number to specify is TP412SRC from Metallics.
