Metallics JSTSP35 – Frequently Asked Questions

1) Do Type A tapping screws like this need a pilot hole, or do they drill their own?
They need a pilot hole. The JSTSP35 is a Type A tapping screw with a gimlet point, so it cuts its own thread in a pre-drilled or punched hole in sheet metal, but it is not a self-drilling screw with a drill tip. Thread pitch is 11 threads per inch to ASME B18.6.4.
2) Will stainless tapping screws cause corrosion if I fasten into aluminum or steel?
They can. Running 18-8 stainless fasteners into aluminum or plain steel sets up a galvanic couple in some environments, and the lesser metal corrodes around the fastener. Outdoors or in damp or coastal locations, isolate the joint or pick a fastener that matches the base metal. Dry indoor work is normally fine.
3) Are these screws Buy American or ARRA compliant for a government job?
No. The JSTSP35 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your contract carries a domestic sourcing clause, these will not satisfy it.
4) What size driver bit do I need for the Metallics JSTSP35 tapping screws?
A #3 Phillips driver. The recess on the JSTSP35 is 0.246 to 0.259 inch in diameter and 0.141 inch deep, which is why a #2 bit cams out on these. Bring a #3 if you are running a jar of 100 with an impact or screw gun.
5) How far will a 12 x 3 in. tapping screw sit above the surface, and how wide is the head?
The pan head measures 0.407 to 0.425 inch across and stands 0.139 to 0.151 inch above the work, to ASME B18.6.3-2013. A pan head is not countersunk, so if you need the fastener flush you want a flat head instead. Length under the head is 3 inches.
6) How much torque can I put on a #12 stainless tapping screw before it snaps?
Minimum torsional strength on these is 83 lb-in. Stainless tapping screws twist off more readily than hardened carbon steel, so set the clutch on your driver rather than running it wide open, especially into heavier gauge metal.
7) How are the Metallics JSTSP35 screws packaged and what is the minimum order?
They ship in a jar of 100, which is the minimum purchase quantity. Jar weight is 2.51 lbs.
8) What are #12 x 3 in. stainless pan head tapping screws typically used for?
They are catalogued for electrical, plumbing, and HVAC work: hanging boxes, straps, clamps, and sheet metal brackets where the 3 inch length lets you reach through insulation, furring, or stacked material into the base. The 18-8 stainless body suits damp or washdown locations where plated steel would rust out.
