Metallics JTRM100 – Frequently Asked Questions

1) What thread size and length are the Metallics JTRM100 machine screws?
They are 1/4-20 by 3/4 inch long. The 1/4-20 thread is the common coarse machine screw size for device boxes, panel covers, strut fittings and ground lugs, and the 3/4 inch length gives you enough reach for a cover plus a tapped hole without bottoming out on shallow prep.
2) Will the JTRM100 screws thread into a 1/4-20 tapped hole in an electrical enclosure or strut nut?
Yes. These are machine screws cut to a 1/4-20 thread, so they mate with any 1/4-20 tapped hole or 1/4-20 nut, including strut channel nuts and tapped enclosure bosses. They are not self-tapping, so the hole has to already be threaded or you need a nut behind it.
3) What drivers can I use on the Metallics JTRM100 tri-drive machine screws?
The JTRM100 round head takes three drivers: a flat blade in the slot, a Phillips bit, or a square (Robertson) bit. That is what tri-drive means here. Handy for electricians working out of a pouch, since whatever driver is already in your hand will turn it.
4) Are these zinc plated steel screws okay for outdoor or damp locations?
The JTRM100 is zinc plated steel. Zinc plating handles indoor and dry or lightly damp conditions, but it is not stainless. For wet locations, coastal air, or anything buried or continuously exposed, specify a stainless 1/4-20 machine screw instead.
5) Is a round head the right choice, or should I use a flat head for a flush finish?
The JTRM100 has a round head, which sits proud of the surface and bears on the face of the part. Use it where a raised head is fine and you want a wider bearing area on sheet metal or slotted covers. If the drawing calls for a flush surface, you need a countersunk flat head with a matching chamfered hole, not this screw.
6) How do the Metallics JTRM100 screws come packaged?
They ship in a jar of 100. That is the shop or van pack, so you are buying a refill container rather than a single fastener, which is what most maintenance crews want for a common 1/4-20 size.
