Metallics JFMP71SS – Frequently Asked Questions
1) Will a 10-24 machine screw thread into a 10-32 tapped hole?
No. The Metallics JFMP71SS is a 10-24 UNC screw at 24 threads per inch, cut to ANSI/ASME B1.1. A 10-32 hole is a finer pitch and the screw will cross-thread or jam. For device boxes and plates tapped 10-32 (the common electrical box thread), you need a 10-32 screw instead. Use this one where the tapped hole or nut is 10-24 coarse.
2) Are these screws Buy American or ARRA compliant for a government job?
No. Metallics JFMP71SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, this part will not satisfy it.
3) How many 10-24 x 3/4 stainless flat head screws come in a jar of JFMP71SS?
They ship in a jar of 100, and 100 is the order minimum. Jar weight is 0.58 lbs.
4) What size Phillips bit drives these screws?
A #2 Phillips. The recess measures 0.198 in. diameter, 0.124 in. deep, with a 0.032 in. slot width, which is standard #2 geometry. Dropping to a #1 bit will cam out and chew the recess.
5) Are 18-8 stainless machine screws strong enough for a structural or load-bearing connection?
Treat them as a general fastening screw, not a structural bolt. The 18-8 stainless material carries a 1050 lb minimum tensile strength and Rockwell B85-B95 hardness, and Metallics notes those figures are guides only because there is no national performance standard for stainless machine screws. They are the right choice for corrosion resistance and moderate elevated temperature, so panels, covers, enclosures, straps and equipment mounting. For a rated structural joint, specify a bolt to a graded standard.
6) Can these stainless screws be used in wet, outdoor, or food processing environments?
That is what the 18-8 stainless is for. The material gives general atmospheric corrosion resistance and holds strength at some elevated operating temperature, which is why it gets used on food processing machinery and refrigeration equipment. For electrical, plumbing, and HVAC work in damp or washdown areas it beats plated steel, which rusts at the head once the coating is scratched.
7) Do these Metallics screws meet a recognized dimensional spec for submittals?
Yes. Head, recess and thread dimensions are built to ASME B18.6.3-1998 for the screw geometry and ANSI/ASME B1.1 for the thread, with SAE as the material standard. Gaging diameter is 0.313 with protrusion 0.025 to 0.042 above gage, which is the recess conformance check an inspector would run.
