Metallics JSTSP20 – Frequently Asked Questions

1) Do I need to pre-drill for a #10 Type A tapping screw, or will it start on its own?
The JSTSP20 is a Type A tapping screw with a gimlet point, meaning it has a sharp pointed tip that starts itself in thin sheet metal, and at 12 threads per inch it forms its own thread as it drives. Type A is intended for thin-gauge sheet and similar soft material, not for thick steel plate; for anything heavy you want a pilot hole or a different point type.
2) Can I use these stainless screws to fasten into aluminum electrical enclosures?
You can, but watch the dielectric pairing. Metallics states that fastening stainless steel parts to aluminum or steel can create a galvanic couple and corrode in some environments. Outdoors, in damp vaults, or in coastal air, isolate the joint or use a fastener that matches the base metal. Indoors and dry, 18-8 stainless on aluminum is common practice.
3) Will these Metallics tapping screws satisfy a Buy American or ARRA requirement on a federal job?
No. The JSTSP20 is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your project carries domestic sourcing language, these screws won't clear it and you'll need a domestically produced fastener.
4) What size driver bit do I need for the Metallics JSTSP20 tapping screws?
A #2 Phillips bit drives the JSTSP20. The recess is a Phillips at 0.124 in. depth and 0.186 to 0.199 in. diameter, so a #2 seats fully; a #1 will cam out and a #3 won't bottom in the recess.
5) How much torque will a #10 18-8 stainless pan head tapping screw take before it snaps?
The JSTSP20 carries a minimum torsional strength of 48 lb-in. Stainless is softer than hardened carbon steel, so if you're running these with an impact driver, back the clutch down. Snapped heads in a panel are the usual result of driving stainless at full trigger.
6) Do these screws meet a dimensional standard I can put on a submittal?
Head dimensions are built to ASME B18.6.3-2013 and the thread to ASME B18.6.4. Note Metallics' own caveat: dimensions for #9 diameter are independent of ASME B18.6.4. The JSTSP20 is a #10 diameter, so it falls inside the thread standard.
7) Are the Metallics JSTSP20 screws sold loose or in a package, and is there a minimum order?
They come in a jar, with a minimum of 100 per jar. So this is a stock-the-van or stock-the-shop quantity rather than a handful of pieces.
8) What trades actually use #10 x 5/8 in. stainless Type A tapping screws?
Metallics lists these for the electrical, plumbing, heating and air conditioning industries. Typical use is mounting straps, plates, boxes and sheet metal duct or panel work where you want corrosion resistance from the 18-8 stainless rather than a plated carbon screw.
