Metallics JFMP64 – Frequently Asked Questions
1) How many 6-32 x 4 in. Metallics flat head machine screws come in a jar, and is there an order minimum?
The JFMP64 flat head Phillips machine screws ship in a jar of 100, and 100 (one jar) is the order minimum. Jar weight is listed at 1.03 lbs.
2) Will a 6-32 x 4 in. machine screw thread into my existing 6-32 tapped hole or nut?
Yes. These are 6-32 UNC, 32 threads per inch, made to ANSI/ASME B1.1 thread standard, so they mate with any standard 6-32 tapped hole, nut, or threaded insert. Dimensions follow ASME B18.6.3-1998, so head and thread geometry match any other spec-conforming #6 flat head machine screw.
3) Do these Metallics machine screws meet Buy American or ARRA requirements for a public project?
No. The JFMP64 screws are listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. On a federally funded job with domestic sourcing requirements, you will need a domestically produced fastener instead.
4) What size driver do I need for Metallics 6-32 flat head Phillips machine screws?
A #2 Phillips bit. The recess is 0.168 in. diameter, 0.094 in. deep, with a 0.029 in. recess width, which is standard Phillips geometry for a #6 screw, so a worn or oversized bit will cam out before it seats the head.
5) How much load will a 6-32 steel zinc machine screw hold?
550 lb minimum tensile strength per screw, with the steel hardened to Rockwell B70-B100 and made from AISI 1006-1022 steel. That is a low-carbon, unhardened-grade fastener: fine for mounting equipment, panels, and fixtures, but not a substitute for a graded cap screw in a structural or high-vibration load path.
6) Is a zinc finish screw OK for outdoor or damp locations?
These are steel with a zinc finish, which gives corrosion resistance for indoor electrical, plumbing, and HVAC work. Zinc plating is a sacrificial coating, so for sustained wet exposure, washdown areas, or coastal sites, specify a stainless machine screw instead rather than relying on zinc.
7) What is the gaging diameter on these flat head screws and why does it matter for inspection?
Gaging diameter is 0.22 in., with protrusion gaging 0.021 to 0.036 in. above the gage. Those are the ASME B18.6.3 head-conformance checks an inspector or QA buyer uses to confirm the head profile is within spec before accepting a lot.
