Metallics TRM15M – Frequently Asked Questions

1) What driver do I need for Metallics TRM15M tri-drive machine screws?
The TRM15M takes a flat blade, a Phillips bit, or a square (Robertson) bit. The tri-drive head is slotted, Phillips and square drive all in one recess, so whatever is already on your belt or in the drill will seat it. That is handy on panel and device work where you are not swapping bits between fasteners.
2) Will an 8-32 x 3/8 in. machine screw thread into a standard electrical box or device ring?
Yes. 8-32 is the standard machine screw thread used for device mounting in outlet boxes, mud rings and cover plates, and the TRM15M is 8-32 with a 3/8 inch length, so it threads into tapped 8-32 holes without a nut. The short 3/8 inch length suits thin steel where a longer screw would bottom out or protrude into the box.
3) Is the round head on these screws going to sit flush, or will it stand proud?
It stands proud. The TRM15M has a round head, not a flat or oval head, so it is not meant for a countersunk hole and it will sit on top of the material with a domed profile. If you need the fastener flush with a plate or panel face, you want a flat head machine screw instead.
4) Are Metallics TRM15M screws OK for damp or outdoor locations?
These are zinc plated steel, which handles indoor and protected locations fine but is not a stainless fastener. In wet locations, coastal air, or anywhere washdown or standing moisture is a factor, the plating will eventually give up and you should specify a stainless 8-32 machine screw instead.
5) Do these 8-32 screws come with nuts, or do I need a tapped hole?
The TRM15M is the screw only, no nuts or washers. Machine screws are made for a pre-tapped hole or a mating nut, so the hole in your box, bracket or ring has to already be threaded 8-32. If you are going into unthreaded sheet metal, use a self-tapping or sheet metal screw instead of this one.
6) Are these Metallics machine screws made in the USA?
Yes, the TRM15M 8-32 x 3/8 in. round head tri-drive machine screw is made in the USA, which matters on public and institutional jobs carrying domestic sourcing language in the spec.
7) I need to order a specific part number for 8-32 x 3/8 round head tri-drive screws. What is it?
Metallics part number TRM15M. That designation covers the 8-32 x 3/8 inch round head tri-drive machine screw in zinc plated steel. There is one configuration under that number, so there is no finish or drive choice to specify.
