Metallics JTRM104 – Frequently Asked Questions
1) What drivers will work on the Metallics JTRM104 tri-drive machine screw?
The JTRM104 has a tri-drive round head, so it takes a flat blade, a Phillips bit, or a square (Robertson) driver. On a panel or box install that means whatever is already on your belt will turn it, and you can swap to a square bit when you need more bite overhead.
2) Will a 1/4-20 machine screw thread into a standard electrical box or panel ground lug?
The JTRM104 is a 1/4-20 UNC thread, 2 inches long. It mates with any 1/4-20 tapped hole or 1/4-20 nut. Note that most steel outlet box and device mounting holes are 8-32 or 10-32, not 1/4-20, so check the tapped size before you order these for box work; 1/4-20 is more common in strut, panel enclosures, and heavier mounting brackets.
3) Is a 2 inch long screw too long for my application?
Machine screws thread the full way, so at 2 inches of length the JTRM104 suits stacked assemblies, thicker brackets, or anywhere you need to pass through several layers and pick up a nut on the far side. For a thin single plate it will stand well proud, since a machine screw does not pull in like a tapping screw.
4) Are these zinc plated screws OK for outdoor or damp locations?
These are steel with zinc plating. Zinc handles indoor and dry locations fine, including panel and enclosure interiors. For wet, coastal, or corrosive exposure, specify stainless steel instead; zinc plating on steel will eventually bloom and rust in standing moisture.
5) Does a round head screw sit flush, or do I need a flat head?
Round head, so it sits on top of the surface with a domed profile, not flush. If your bracket or cover is countersunk and the fastener has to finish level, this is the wrong head style and you want a flat head machine screw instead.
6) Do these Metallics machine screws come with nuts?
No. The JTRM104 ships as screws only, 100 to the jar. If the hole you are fastening into is not already tapped 1/4-20, order 1/4-20 hex nuts and any washers separately.
7) How do Metallics JTRM104 screws come packaged?
They come in a jar, 100 pieces. That is a shop or truck-stock quantity rather than a loose handful, so it suits an MRO cage or a service van where you want 1/4-20 x 2 on hand without reordering per job.
