Metallics TRM101M – Frequently Asked Questions

1) What drivers will turn a Metallics TRM101M tri-drive machine screw?
The TRM101M round head takes three drivers: a flat blade in the slot, a Phillips bit, or a square (Robertson) bit. That is the point of a tri-drive head, you use whatever is already on the belt or in the pouch, which is why electricians favor them for panel and box work.
2) Is a machine screw like the TRM101M the right fastener for wood or drywall?
No. The TRM101M is a machine screw with a 1/4-20 machine thread and a blunt end, so it needs a tapped hole, a nut, or a threaded insert. It will not cut its own thread in wood, drywall, or sheet metal. For those substrates you want a wood screw, a self-drilling sheet metal screw, or a drywall anchor and bolt.
3) Is the round head on the TRM101M going to sit flush, or does it stand proud of the surface?
It stands proud. The head type is round, a domed head that seats on top of the material rather than sinking into it, so no countersink is required in the mounting hole. If the spec calls for a flush surface, you need a flat head screw and a countersunk hole instead.
4) Are zinc plated steel machine screws OK for outdoor or damp locations?
The TRM101M is zinc plated steel. Zinc gives decent corrosion resistance for dry interior work, panel interiors, and covered locations, but it is not stainless. For wet locations, coastal exposure, or anywhere washdown or standing moisture is expected, specify a stainless steel machine screw instead.
5) Does the TRM101M come with nuts or washers?
No. The TRM101M is the screw only, a 1/4-20 x 1 in. round head tri-drive in zinc plated steel. If the connection is not into an already tapped hole, order 1/4-20 hex nuts and any flat or lock washers separately.
6) Are Metallics tri-drive machine screws made in the USA?
Yes, the TRM101M is US made, which matters on public and institutional jobs carrying domestic sourcing requirements on fasteners.
7) How do I make sure I order the right length and thread for a tri-drive machine screw?
There is one configuration here: model TRM101M, 1/4-20 thread, 1 inch length, round head, zinc plated steel. Nothing else to specify. Measure your stackup thickness and add enough to fully engage the nut or tapped hole; if 1 inch leaves you short, look to a longer 1/4-20 in the same tri-drive family rather than forcing partial thread engagement.
