Metallics JFM135 – Frequently Asked Questions

1) What thread does the Metallics JFM135 machine screw take, and will it run into a standard 3/8-16 nut or tapped hole?
The JFM135 is a 3/8-16 UNC machine screw, 16 threads per inch, cut to ANSI/ASME B1.1. That is the standard coarse thread for 3/8 inch fasteners, so it threads into any 3/8-16 tapped hole, nut, or strut channel nut without an adapter. Overall length is 4 inches.
2) Will a 3/8-16 x 4 in. flat head slotted screw sit flush in a countersunk hole?
Yes, if the hole is countersunk for a standard flat head. The JFM135 has a flat head measuring 0.67 to 0.717 in. across with a head height of 0.2 to 0.23 in., built to ASME B18.6.3-1998, so it drops into any countersink cut to that standard and finishes flush with the surface. A plain drilled hole with no countersink will leave the head proud.
3) Are zinc plated steel machine screws okay outdoors or in a damp mechanical room?
The JFM135 is steel with a zinc finish, which gives corrosion resistance for indoor and sheltered work: panels, enclosures, device mounting, HVAC and plumbing equipment. For sustained wet exposure, washdown, or coastal air, zinc plating will eventually sacrifice and rust, so a stainless machine screw is the better call there.
4) Do these Metallics machine screws qualify for a Buy American or ARRA funded job?
Metallics lists the JFM135 as both Buy American compliant and ARRA compliant. Country of origin is shown as multiple, so if your specification requires a single documented country of melt and manufacture, that is a detail to confirm at order.
5) What grip length will a 4 inch 3/8-16 machine screw handle?
At 4 inches overall measured from under the flat head (flat heads are measured overall to length), the JFM135 covers combined material thickness up to about 4 inches less the nut and washer stack. For thicker assemblies you need a longer screw or a threaded rod and two nuts.
