Metallics JFM15 – Frequently Asked Questions

1) What thread does the Metallics JFM15 machine screw use, and will it run into a standard 4-40 tapped hole?
The JFM15 is a 4-40 UNC machine screw, 40 threads per inch, made to ANSI/ASME B1.1. It threads into any #4-40 tapped hole or 4-40 nut, which is the common thread on device mounting holes and small enclosure hardware. Shank length is 3/8 inch.
2) Will a flat head 4-40 screw sit flush in a countersunk hole?
Yes, that is what the flat head is for. The JFM15 head measures 0.191 to 0.212 inch across and 0.055 to 0.067 inch high, so it seats down into an 82 degree countersink and finishes flush with the surface. If your hole is not countersunk, the head will stand proud and you want a pan or round head instead.
3) Are these zinc plated steel screws OK outdoors or in a damp location?
Zinc plated carbon steel is a dry indoor finish. The JFM15 is AISI 1006-1022 steel with a zinc plating, which handles panel interiors, enclosures and electronics work, but it will corrode in wet, exterior or washdown locations. For those, go to a stainless machine screw of the same 4-40 x 3/8 size.
4) How many 4-40 x 3/8 flat head screws come in a Metallics JFM15 jar?
They ship 100 to a jar, and 100 count is the order minimum. Metallics lists other sizes and quantities as available by request if you need a different length or a bulk count.
5) Do these Metallics machine screws meet Buy American or ARRA requirements on a government job?
Metallics lists the JFM15 as ARRA compliant and Buy American compliant, with China as the country of origin. If your spec requires domestic melt and manufacture rather than the Buy American compliance Metallics states, confirm against the exact clause in your contract.
6) What dimensional standard do these flat head machine screws follow, so I know the head will match my countersink?
Head geometry on the JFM15 is built to ASME B18.6.3-1998, the inch standard for slotted and recessed head machine screws, and threads to ANSI/ASME B1.1. Anything countersunk to that standard for a #4 flat head will take this screw.
