Metallics JSTSP28 – Frequently Asked Questions

1) Is the Metallics JSTSP28 #12 tapping screw sold individually or by the jar?
It ships as a jar of 100. The order minimum is 100 pieces, packed in a jar, so a single screw is not a sellable quantity.
2) Will a #12 Type A tapping screw cut its own thread in sheet metal, or do I need to tap the hole first?
Type A tapping screws with a gimlet point form their own thread in a pilot hole in thin sheet metal, so no separate tapping operation is needed. The thread is 11 threads per inch to ASME B18.6.4, and the gimlet point starts the hole without wandering. You still need a pilot hole sized for the material gauge.
3) Can I use 18-8 stainless tapping screws into aluminum enclosures or steel strut?
Mechanically yes, but watch the dissimilar metals. Fastening 18-8 stainless into aluminum or steel can set up a galvanic couple and corrode the base metal in wet or coastal environments. Indoors and dry it is routine; outdoors against aluminum, isolate the joint or use a matched-material fastener.
4) Does the JSTSP28 screw meet Buy American or ARRA requirements for a government job?
No. It is not Buy American compliant and not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing requirements, this one will not pass.
5) What size driver bit do I need for the JSTSP28 pan head tapping screws?
A #3 Phillips bit. The recess is a Phillips drive with a 0.246 to 0.259 inch recess diameter and 0.141 inch depth, so a #2 bit will cam out and chew the recess on a #12 screw.
6) How much torque can a Metallics #12 x 1 in. stainless tapping screw take before it snaps?
Rated at 83 lb-in minimum torsional strength. That is the driving limit, so set clutch-equipped drivers below it; stainless work-hardens and twists off rather than stripping the recess.
7) How much does the pan head on the JSTSP28 stand off the surface, and how wide does it sit?
Head width runs 0.407 to 0.425 inches with a head height of 0.139 to 0.151 inches. That footprint covers a slightly oversized or slotted hole in a panel while keeping the profile low enough to clear a cover plate.
8) Is the Metallics #12 x 1 in. pan head screw made to a dimensional standard I can submit on a spec?
Head and recess dimensions follow ASME B18.6.3-2013, and the thread form follows ASME B18.6.4. Note that dimensions for the #9 diameter in this series fall outside ASME B18.6.4; the #12 does not have that caveat.
9) What trades and jobs is the Metallics JSTSP series tapping screw intended for?
It is specified for electrical, plumbing, heating and air conditioning work, the kind of screw used for mounting boxes, straps, duct components and panel hardware. The 1 inch length handles a head plus a sheet metal or thin base material grip.
10) Can I get the Metallics JSTSP tapping screws in a different length or a bigger jar?
Yes, other diameters, lengths and pack quantities in the JSTSP series are available by request. The JSTSP28 covers the #12 diameter at 1 inch.
