Metallics TRM20M – Frequently Asked Questions

1) What drivers will turn a Metallics TRM20M tri-drive machine screw?
The TRM20M round head takes a flat blade, a Phillips bit, or a square (Robertson) bit. That is the point of the tri-drive head: whatever is already on the electrician's belt will seat it, so there is no bit hunting in a panel or box.
2) Will a 10-32 x 3/8 in. machine screw thread into a standard outlet box or device?
Yes. 10-32 is the thread used for device mounting and ground screw holes in steel boxes and enclosures, and the TRM20M is a 10-32 with a 3/8 inch length, so it bites the tapped hole without bottoming out or standing proud behind a plate.
3) Is the Metallics TRM20M suitable for outdoor or damp locations?
It is zinc plated steel, which handles indoor and normally dry conditions and gives moderate corrosion resistance. For wet, coastal, or chemically aggressive locations, specify a stainless fastener instead; zinc plating will eventually sacrifice and rust through.
4) Do I need a machine screw or a self-tapping sheet metal screw for mounting in a steel enclosure?
Use the TRM20M machine screw when the hole is already tapped, as device holes and enclosure mounting holes in boxes usually are. If you are fastening into unthreaded sheet metal with no tapped hole, a machine screw will not hold and you want a self-drilling or self-tapping screw instead.
5) Is a round head the right choice, or should I use a flat head screw?
The TRM20M has a round head, which seats on top of the surface and needs no countersink. If the drawing calls for a flush face, such as a hole that is countersunk for a cover or a surface that something slides across, a flat head is the correct part instead.
6) Are Metallics TRM20M screws made in the USA?
Yes, the TRM20M is US made, which matters on public and federally funded work where domestic-source fasteners are called out on the submittal.
7) How do I order the right Metallics tri-drive screw, and is TRM20M one size only?
TRM20M is a single configuration: 10-32 thread, 3/8 inch length, round tri-drive head, zinc plated steel. There are no finish or length options to pick on this part number, so order by the TRM20M designation and step to a different Metallics number if you need a longer screw.
