Metallics JTRM22 – Frequently Asked Questions

1) What thread size and length are the Metallics JTRM22 machine screws?
The JTRM22 is a 1/4-20 machine screw, 3/8 inch long under the head. That is a coarse 20 threads per inch on a 1/4 inch diameter body, so it mates with any 1/4-20 tapped hole, strut nut, or spring nut. At 3/8 inch it is a short screw, meant for thin sheet steel enclosures, box covers, and strut hardware rather than stacked material.
2) Are these zinc plated steel screws OK for outdoor or wet locations?
The JTRM22 is zinc plated steel, which is a dry-location plating. It handles indoor panel work, boxes, and strut inside a conditioned building fine, but in a wet, damp, or coastal exposure zinc will give up before stainless does. For outdoor gear, exterior strut, or washdown areas, specify a stainless 1/4-20 machine screw instead.
3) What driver do I need for a tri-drive round head screw like the Metallics JTRM22?
Three will work. The round head is cut for slotted, Phillips, and square drive, so an electrician can set it with a flat blade, a #2 Phillips, or a square bit without changing tools on the ladder. That is the point of the tri-drive head: whatever is already in your pouch will turn it.
4) Will a 1/4-20 x 3/8 in. machine screw work with Unistrut style channel nuts?
Yes, thread-wise. Strut channel nuts are commonly 1/4-20, 3/8-16, and 1/2-13, so a 1/4-20 screw threads straight into a 1/4-20 spring nut. Watch the length: at 3/8 inch the JTRM22 only has enough reach for a thin clamp or strap plus the nut. If you are stacking a strap over a backing plate, move up to a longer 1/4-20 screw.
5) Is the Metallics JTRM22 a machine screw or a self-tapping screw?
Machine screw. It needs an existing tapped hole or a nut, it will not cut its own threads in sheet metal. For fastening into unthreaded sheet you want a self-drilling or sheet metal screw instead. For a factory-tapped enclosure boss, ground lug, or channel nut, the 1/4-20 thread on the JTRM22 is what you want.
6) Are Metallics tri-drive machine screws made in the USA?
Yes, the JTRM22 round head tri-drive machine screw is made in the USA. That matters on public and institutional jobs carrying domestic material requirements, so it is worth noting on the submittal.
7) How do Metallics JTRM22 screws come packaged for a service truck?
They ship in a jar, which is how most electrical shops like small fasteners for the van: sealed, stackable, and easy to pour a handful from without losing the rest into the bottom of a bin.
