Metallics JFM84SS – Frequently Asked Questions
1) Will an 8-32 machine screw thread into standard electrical device boxes and cover plates?
Yes. The Metallics JFM84SS is an 8-32 UNC thread with 32 threads per inch, cut to ANSI/ASME B1.1, which is the thread used for device mounting in outlet and switch boxes. At 1/2 inch long it suits box ears and plate mounting rather than deep build-ups of mud rings and spacers, where you would step up to a longer screw.
2) Do these screws qualify for a Buy American or ARRA funded job?
No. Metallics JFM84SS flat head stainless machine screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On federally funded work with domestic sourcing requirements you will need a domestically produced fastener instead.
3) Are stainless machine screws worth it for damp or washdown locations instead of plated steel?
For general atmospheric corrosion resistance, yes, and that is the stated use case for these 18-8 stainless screws, along with food processing machinery and refrigeration equipment. 18-8 also holds its strength better than steel at elevated operating temperatures. On dry interior work a plated steel screw will do the same mechanical job; the premium here buys corrosion life in kitchens, coolers, exterior enclosures, and wet or coastal environments.
4) How do these Metallics 8-32 screws come packaged and what is the minimum I can order?
They ship in a jar, with a minimum of 100 pieces per jar. That makes it a restock item for a van or a shop bin rather than a count-out-a-dozen purchase.
5) Is a machine screw the right choice here, or do I need a self-tapping or sheet metal screw?
A machine screw like the JFM84SS has a straight, uniform 8-32 UNC thread with no point, so it needs an existing tapped hole or a nut to thread into. If you are fastening into unthreaded sheet metal or a pilot hole with no threads, a sheet metal or self-tapping screw is the right part. Metallics lists this one for electrical, plumbing, heating and air conditioning work, where tapped device boxes, enclosures, and equipment chassis are the norm.
