Metallics JFMP103SS – Frequently Asked Questions
1) How many screws come in a jar of Metallics JFMP103SS 1/4-20 machine screws?
The JFMP103SS ships as a 100-piece jar, and 100 is the order minimum. The pack type is a jar rather than a loose bag, which is why it holds up in a truck bin or on a shelf cart.
2) What size Phillips driver do I need for these 1/4-20 flat head machine screws?
A #3 Phillips bit is the correct driver. The recess measures 0.276 inch diameter at 0.16 inch deep, so a #2 bit will sit high in the recess and cam out, especially driving into a tapped box or strut nut.
3) Will these thread into a standard 1/4-20 tapped hole or strut nut?
Yes. The thread is 1/4-20 UNC, 20 threads per inch, cut to ANSI/ASME B1.1, so it mates with any standard 1/4-20 tapped hole, channel nut, or coupling. Gaging diameter is 0.424.
4) Can I use these on a federally funded job with Buy American requirements?
No. The JFMP103SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a job with domestic sourcing language in the spec, you need a domestically produced fastener instead.
5) Are these 18-8 stainless screws OK for outdoor or washdown use?
18-8 stainless is the grade used where general atmospheric corrosion resistance is needed, including food processing machinery and refrigeration equipment. It also holds strength better than plain steel as operating temperature rises. For salt spray or chloride-heavy marine exposure, 18-8 is not the grade people specify.
