Metallics JFM114 – Frequently Asked Questions
1) Will the Metallics JFM114 machine screw thread into a 1/2-13 tapped hole or standard 1/2 inch coarse nut?
Yes. The JFM114 is a 1/2-13 UNC screw, 13 threads per inch, cut to ANSI/ASME B1.1. That is the standard coarse series for 1/2 inch diameter, so it mates with any 1/2-13 tapped hole, nut, or strut channel nut. If the hole you are threading into is 1/2-20 fine, this screw will not start.
2) Do these Metallics screws qualify for a Buy American or ARRA funded job?
No. The JFM114 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements, you will need a domestically manufactured fastener instead.
3) How many 1/2-13 x 1 in. Metallics flat head screws come in a jar?
They ship 100 to a jar, and the jar is the order minimum, so the smallest buy is 100 pieces. Jar weight is listed at 5.52 lbs. If you need a count other than 100, Metallics states other sizes and quantities are available by request.
4) Are zinc plated steel machine screws okay outdoors or in a wet location?
Zinc plated carbon steel is the finish here, which suits dry indoor use, panels, enclosures, and electronics work. It is a sacrificial plating, not stainless, so in rain, washdown, or coastal exposure it will eventually bloom white and then rust. For wet or corrosive locations, specify a stainless flat head machine screw in the same 1/2-13 x 1 in. size.
5) Is a machine screw the right choice, or do I need a bolt or sheet metal screw for mounting to a panel?
A machine screw like this 1/2-13 x 1 in. flat head is fully threaded for its length and meant to go into a pre-tapped hole or take a nut. It will not cut its own thread, so it is the wrong part for driving straight into unthreaded sheet metal, where a self tapping or sheet metal screw belongs. Pick the flat head version, as here, when the fastener has to finish flush in a countersunk hole; a pan or hex head is the choice when a raised head is acceptable and you want a better driving surface.
