Metallics JSTSP27 – Frequently Asked Questions

1) Do the Metallics JSTSP27 #12 tapping screws need a pilot hole, or will they cut their own thread in sheet metal?
The JSTSP27 is a Type A tapping screw with a gimlet point, so it starts and forms its own thread in thin sheet material like panel enclosures and duct without pre-drilling. Thread pitch is 11 threads per inch to ASME B18.6.4. In heavier gauge stock or into plastic housings a pilot hole still gives you better control of the start and keeps you under the 83 lb-in minimum torsional rating.
2) Will #12 pan head screws hold up outdoors or in a damp mechanical room?
Yes. These #12 x 3/4 in. pan head screws are 18-8 stainless, which is the austenitic grade used where plated carbon steel would rust out, so wet mechanical rooms, exterior enclosures and coastal-adjacent jobs are fair use. Keep in mind stainless tapping screws run softer than case-hardened carbon steel, so drive them at lower speed and respect the 83 lb-in torsional minimum to avoid snapping heads.
3) Can I use these on a federally funded project with Buy American requirements?
No. The Metallics JSTSP27 screws are listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your contract carries a domestic-sourcing clause, these won't satisfy it and you'll need a domestically produced stainless tapping screw instead.
4) What driver bit do I need for the Metallics JSTSP27 Phillips tapping screws?
A #3 Phillips bit. The recess is 0.246 to 0.259 inch in diameter, 0.141 inch deep, with a 0.034 inch recess width, which is why a #2 bit cams out and chews the recess on a #12 screw. Load a #3 in the impact or screwgun before you start a panel of these.
5) Will these #12 screws interchange with the pan head tapping screws already in my panel stock?
Dimensionally, yes, as long as what you have is also a #12 pan head Type A. Head and recess dimensions are built to ASME B18.6.3-2013 and the thread to ASME B18.6.4, so the screws are interchangeable with any other screw made to those same standards. Where they will not interchange is thread form: a Type A at 11 TPI is a coarse sheet-metal thread and will not chase the finer thread a Type AB or Type B screw cut in an existing hole.
6) How are the Metallics JSTSP27 screws packaged and what is the minimum order?
They ship in a jar, with an order minimum of 100 pieces (one jar). Jar weight is listed at 0.88 lbs. For MRO stockrooms that's a sensible bin quantity to standardize on for enclosure and HVAC work rather than buying loose.
