Metallics JSTSP41 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JSTSP41 #4 x 1/2 in. tapping screws?
A #1 Phillips bit. The recess is 0.109 to 0.122 in. in diameter, 0.078 in. deep and 0.019 in. wide, so a #2 bit will ride high in the recess and cam out. Keep a #1 in the pouch if you are running these in panel or box work.
2) Do I need to drill a pilot hole for a Type A tapping screw, or will it start on its own?
The JSTSP41 is a Type A tapping screw with a gimlet point, meaning it comes to a sharp tip and forms its own thread as it drives into sheet metal or thin stock. In thin sheet it will start on its own; in heavier gauge a pilot hole is still the right call so you do not snap a #4 shank. Thread pitch is 24 per inch.
3) Will stainless tapping screws cause corrosion if I drive them into aluminum enclosures?
They can. 18-8 stainless fastened into aluminum or steel can set up a galvanic couple in some environments, which corrodes the softer base metal around the screw. For outdoor or wet aluminum enclosures, isolate the joint or use a fastener matched to the base metal. In dry interior work the 18-8 material is the reason to pick it, since the screw itself will not rust.
4) Can I use these screws on a federally funded job with domestic content requirements?
No. The JSTSP41 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a job carrying domestic preference clauses you need a fastener sourced and certified as domestic.
5) How are the Metallics JSTSP41 screws packaged and what is the minimum I can buy?
They ship in a jar, 100 count, and 100 is the order minimum. That is a shop-stock quantity rather than a single fastener, which suits MRO carts and service vans where #4 x 1/2 in. stainless tappers get used a few at a time across many jobs.
6) What standards do these Metallics tapping screws conform to?
Head and recess dimensions follow ASME B18.6.3-2013 and the thread form follows ASME B18.6.4, the tapping screw thread standard. If a submittal calls out B18.6.4 Type A threads, the JSTSP41 meets that designation.
