Metallics JPMP121 – Frequently Asked Questions
1) Is the Metallics JPMP121 a machine screw or a self-tapping screw?
It's a machine screw. The 12-24 designation is a machine thread, so it needs a tapped hole or a nut, not raw sheet metal or wood. The common use is threading into a tapped hole in a steel box, panel or enclosure. If you need something that cuts its own thread in unthreaded sheet metal, a machine screw is the wrong part.
2) Will a 12-24 x 1 inch screw fit the tapped holes in a standard electrical box or panel?
Yes for anything prepped 12-24, which is the usual thread on steel outlet box ears, panel mounting rails and enclosure flanges. The 1 inch length gives room to pass through a cover, ring or mounting plate and still get full thread engagement. Just confirm the hole is 12-24 and not 10-32, which is the other thread you'll meet on this gear and is not interchangeable.
3) Are these Metallics 12-24 screws plated for corrosion resistance?
They're steel with a zinc plating, which handles dry indoor and protected locations fine. For wet, outdoor or corrosive environments, step up to stainless rather than zinc plated steel.
4) Is 1 inch too long for mounting a device or cover to a box?
It can be. One inch is a long run of thread for a flush cover screw, and in a shallow box the tip can bottom out or interfere with conductors and device terminals. Use the 1 inch length where you're stacking material, mounting through a plaster ring, spacer or bracket. For a cover straight onto a tapped flange, a shorter 12-24 is the better call.
5) What driver do I need for the Metallics JPMP121 screws?
A Phillips bit. The head is a pan head with a Phillips recess, so a standard #2 Phillips driver or bit seats it. The pan head sits flat on the surface without needing a countersunk hole.
6) How many screws come in a jar of Metallics JPMP121?
100 screws per jar. The jar pack is the usual van-stock or shop-bench format, so it suits an electrician carrying a running supply of 12-24 hardware rather than a one-off repair.
7) What is the Metallics part number for the 12-24 x 1 pan head Phillips machine screw jar?
JPMP121 is the Metallics number, covering the 12-24 x 1 inch pan head Phillips machine screw in zinc plated steel, packed 100 to a jar.
