Metallics JFMP101SS – Frequently Asked Questions

1) How deep a countersink do I need for these 1/4-20 flat head machine screws to sit flush?
The flat head measures 0.442 to 0.477 inch across and 0.131 to 0.153 inch high, so an 82 degree countersink of roughly half an inch diameter will take it flush. The gaging diameter is 0.424 inch with protrusion 0.029 to 0.050 above, and the head geometry follows ASME B18.6.3-1998.
2) Can I use these outdoors or in a wet/washdown area instead of plated steel screws?
That is what the 18-8 stainless is for. These screws are specified for general atmospheric corrosion resistance and are used in food processing machinery and refrigeration equipment, so damp, washdown, and exterior-exposed work suits them where zinc plated steel would rust. Stainless also holds strength better than plain steel at elevated operating temperatures.
3) Are these Metallics screws Buy American or ARRA compliant for a government job?
No. The JFMP101SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a federally funded project with domestic sourcing language, you need a domestically produced fastener instead.
4) What size Phillips bit do these Metallics stainless machine screws take?
A #3 Phillips driver. The recess is 0.276 inch in diameter and 0.16 inch deep, so a #2 bit will cam out and chew the recess on a 1/4-20 head. Have a #3 in the pouch before you start the run.
5) How many 1/4-20 x 1 in. screws come in a jar, and is there a minimum order?
They ship in a jar of 100, and 100 is the order minimum. The packed jar weighs 1.3 lbs.
6) How much load will a 1/4-20 18-8 stainless machine screw hold?
1900 lb minimum tensile, with hardness in the Rockwell B85 to B95 range. One caution worth knowing: there is no national standard for hardness and tensile performance on stainless machine screws, so those figures are guides rather than a graded rating. If your drawing calls for a Grade 5 or Grade 8 number, a stainless machine screw is not the part that satisfies it.
