Metallics JFMP105SS – Frequently Asked Questions

1) Will the head sit flush in a standard 1/4-20 countersink?
Yes, if the countersink is cut to the ASME B18.6.3 flat head profile. Head width runs 0.442 to 0.477 inch with a head height of 0.131 to 0.153 inch, which is the standard 82 degree flat head envelope for a 1/4-20 screw. In a hole drilled straight with no countersink, the head will stand proud by roughly that head height.
2) Will these thread into a standard 1/4-20 tapped hole or coarse nut?
Yes. These are UNC threads at 20 threads per inch to ANSI/ASME B1.1, which is the standard coarse 1/4-20 series, so they mate with any 1/4-20 UNC tapped hole, coupling or hex nut. They are not fine thread (1/4-28), so don't mix them with 28 TPI hardware.
3) Is the Metallics JFMP105SS screw Buy American or ARRA compliant for a government job?
No. These 18-8 stainless machine screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic-content requirement, this part won't satisfy it.
4) What driver bit do I need for these 1/4-20 flat head Phillips machine screws?
A #3 Phillips bit. The recess on these 18-8 stainless screws measures 0.276 inch in diameter and 0.16 inch deep, so a #2 bit will sit loose in the recess and cam out, especially driving 1/4-20 threads into a tapped hole.
5) Are stainless machine screws the right choice for damp or washdown areas, or should I use plain steel?
18-8 stainless is what you want where there's general atmospheric corrosion to deal with, including food processing machinery and refrigeration equipment. It also holds its strength better than plain steel as operating temperature climbs. For a dry interior panel with no moisture exposure, zinc plated steel does the same mechanical job; the premium here buys corrosion resistance.
6) What does the jar of 100 Metallics 1/4-20 x 3 inch screws weigh for shipping or tool-bag use?
3.32 lbs for the jar of 100. That's worth knowing if you're stocking a van or a shop crib, since the jar itself is the only pack configuration offered.
