Metallics TRM81M – Frequently Asked Questions
1) What driver do I need for the Metallics TRM81M tri-drive machine screw?
The TRM81M round head takes three drivers: a flat blade in the slot, a Phillips bit, or a square drive bit. Whatever is already on your belt or in the drill will seat it, which is the point of a tri-drive head on service work where you are not carrying a full bit set.
2) Is a zinc plated steel screw okay for a damp or outdoor electrical box?
The TRM81M is steel with a zinc plating, which handles dry interior and normally occupied areas fine. Zinc plating is a sacrificial coating, not stainless, so in a wet location, a wash-down area, or anywhere coastal, specify a stainless 6-32 machine screw instead and keep the zinc ones for interior work.
3) Why pick a round head instead of a flat head 6-32 screw?
Round head sits proud on the surface and needs no countersink, so it is the right choice for mounting to a flat bracket, strap or box ear. If the hole in your part is chamfered for a flush finish, or the screw head has to clear a cover plate or a moving part, a flat head 6-32 is the one to order rather than the TRM81M.
4) Is the Metallics TRM81M a machine screw or a sheet metal screw?
It is a machine screw, 6-32 x 3/4 in., with a uniform machine thread meant for a tapped hole or a nut. It will not cut its own threads in sheet steel the way a self-tapping sheet metal screw does, so if you are fastening into an untapped panel you need a tapping screw, not this one.
5) Who makes the TRM81M tri-drive screws and are they domestic?
These are Metallics, part number TRM81M, and they are made in the USA, which matters on public and institutional jobs carrying a domestic sourcing requirement.
