Metallics JFM104 – Frequently Asked Questions
1) What thread does the Metallics JFM104 machine screw take, and will it thread into a standard 1/4-20 tapped hole or nut?
It's a 1/4-20 UNC thread, 20 threads per inch, made to ANSI/ASME B1.1. That means it threads into any standard 1/4-20 coarse tapped hole, nut, or strut channel nut. Overall length is 2 inches.
2) Will a flat head slotted machine screw sit flush in a countersunk hole in an enclosure or device plate?
Yes, that's what the flat head is for. The JFM104 head measures 0.442 to 0.477 in. across with a head height of 0.131 to 0.153 in., built to ASME B18.6.3-1998, so it drops into a standard 82-degree countersink for a 1/4-20 flat head screw and finishes flush with the surface.
3) Can I use these on a federally funded job with Buy American requirements?
No. The JFM104 is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. For a project with domestic sourcing language in the spec, you need a domestically produced fastener instead.
4) Are these zinc plated screws OK for outdoor or damp locations?
The JFM104 is low carbon steel with a zinc finish. Zinc plating handles indoor, dry, and lightly damp conditions, which covers most panel, enclosure, and device work. For wet locations, exterior use, or corrosive or coastal environments, go with a stainless machine screw of the same 1/4-20 x 2 in. size instead, since plating will eventually give up on steel.
5) How are these machine screws packaged and what is the minimum I can buy?
They come in a jar, 100 pieces, and 100 is the order minimum. Jar weight is 2.55 lbs. If you need a different size or a larger count, Metallics offers other sizes and quantities in the FM and FMP series by request.
6) Do these 1/4-20 screws come with nuts or washers?
No, the jar is screws only, 100 flat head slotted machine screws. Order 1/4-20 hex nuts, lock nuts, or flat washers separately if the assembly needs them. In a tapped hole or a strut channel nut, no additional hardware is needed.
7) What trades actually use a 1/4-20 x 2 in. flat head slotted machine screw?
Metallics positions the FM series for electrical, plumbing, and heating and air conditioning work. The 2 in. length gives you enough reach to go through a device plate plus spacers or a thick mounting surface and still pick up a nut or tapped hole on the far side, and the flat head keeps the face clean where a protruding head would interfere.
