Metallics JSTS20 – Frequently Asked Questions

1) What size and thread does the Metallics JSTS20 tapping screw have?
The JSTS20 is a #10 diameter by 5/8 inch long Type A tapping screw with 12 threads per inch and a gimlet point. Thread form follows ASME B18.6.4 and head dimensions follow ASME B18.6.3-2013. The pan head measures 0.357 to 0.373 inch across and 0.099 to 0.11 inch high, so it seats flat against a plate or strap without much stand-off.
2) Can I use stainless tapping screws to fasten into aluminum or steel?
Mechanically yes, but watch the metals. Fastening stainless parts to aluminum or steel can set up a galvanic couple and corrode in some environments, so in wet or coastal locations pair the 18-8 stainless screw with an isolating washer or choose a fastener that matches the base metal. In dry interior electrical work the 18-8 material is the reason to pick it.
3) Will a #10 self-tapping screw hold in sheet metal enclosures and strut without a pre-tapped hole?
That is what a Type A tapping screw is built for. The gimlet point starts in a drilled or punched pilot hole in sheet metal and forms its own thread as it drives, so no tapping operation is needed. The screw is rated to 48 lb-in minimum torsional strength, which is the driving torque it will take before the shank twists off, so keep an impact driver off it and set the clutch low.
4) Are Metallics JSTS20 screws Buy American or ARRA compliant for a government job?
No on both counts. The JSTS20 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your spec carries a domestic sourcing clause, this screw will not clear submittal.
5) How are Metallics JSTS20 screws packaged and what is the minimum order?
They come in a jar of 100, and 100 is the minimum order quantity. Jar weight is 0.52 lbs. Metallics lists other sizes and quantities in the JSTS line by request if 5/8 inch is not the length you need.
6) What trades use this kind of stainless pan head tapping screw?
Metallics lists the JSTS series for electrical, plumbing, heating and air conditioning work: mounting straps, plates, covers and sheet metal components where an 18-8 stainless fastener is wanted for corrosion resistance. The pan head gives full bearing on a clearance hole with no countersink prep.
