Metallics FM137 – Frequently Asked Questions

1) Will a Metallics FM137 machine screw thread into a standard 3/8-16 tapped hole or nut?
Yes. The FM137 is a 3/8-16 UNC thread, 16 threads per inch, made to ANSI/ASME B1.1. That is the standard coarse thread for 3/8 inch fasteners, so it mates with any 3/8-16 nut, strut channel nut, or tapped hole.
2) Is a zinc plated machine screw suitable for outdoor or damp locations?
The FM137 is zinc plated carbon steel, which is a mild indoor corrosion coating. It holds up fine in panels, enclosures, and conditioned interior spaces. For wet locations, exterior runs, coastal air, or anything washed down, specify a stainless machine screw instead.
3) Can I buy a single FM137 screw or is there a minimum order?
These ship boxed with a 25 each minimum, so the smallest order is a 25 piece box of 3/8-16 x 6 in. flat head slotted screws.
4) Will these machine screws meet a Buy American requirement on a federal or institutional job?
The Metallics FM137 is listed as both Buy American compliant and ARRA compliant, with country of origin reported as multiple. Procurement officers on federally funded work typically need that documented per shipment, so request the mill or compliance paperwork with the order.
5) Does a machine screw like this cut its own thread in metal?
No. A machine screw has a straight machine thread and needs a mating nut or a hole already tapped 3/8-16. If you are fastening into bare sheet metal or an untapped hole, you want a self-tapping or thread-forming screw, not the FM137.
6) What are 3/8-16 x 6 in. flat head slotted machine screws normally used for?
They are a trade fastener for electrical, plumbing, and HVAC work, typically through-bolting equipment, hanging or bracket work, and panel and enclosure assembly where the head has to sit flush. The 6 inch length is for reaching through thick build-ups or spacers rather than sheet metal. Nuts and washers are separate items.
