Metallics JSTSP18 – Frequently Asked Questions

1) How are the Metallics JSTSP18 #8 x 2 in. stainless tapping screws packaged and what is the minimum order?
They ship in a jar, 100 screws per jar, and the jar is the minimum order unit. So the smallest purchase is 100 pieces rather than a single screw. Jar weight is listed at 0.98 lbs.
2) Will a #8 x 2 in. Type A tapping screw bite into sheet metal without a pre-drilled hole?
The JSTSP18 is a Type A tapping screw with a gimlet point, which is the sharp, pointed thread form meant for thin sheet metal, and it cuts its own thread as it drives. Thread count is 15 threads per inch, the coarse spacing Type A uses for sheet material. In heavier gauge or in hardwood framing, drill a pilot hole; the point is for thin stock, not for drilling.
3) Can I use 18-8 stainless screws to fasten into aluminum or steel enclosures?
You can, but be aware of the galvanic risk. Metallics notes that fastening stainless steel parts to aluminum or steel can set up a galvanic couple and cause corrosion in some environments. Indoors and dry, it is usually a non-issue. Outdoors, coastal, or anywhere wet, an isolating washer or a matched-material screw is the better call for aluminum.
4) Are the JSTSP18 screws Buy American or ARRA compliant for a federally funded job?
No. The JSTSP18 is not Buy American compliant and is not ARRA compliant, and the country of origin is listed as multiple. If your project carries domestic sourcing requirements, this part will not satisfy them.
5) Are these stainless tapping screws strong enough to drive with an impact driver?
Torsional strength is rated at 39 lb-in minimum, which is the twist the screw will take before the head shears. Stainless tapping screws snap more readily than hardened steel, so set a low clutch on a drill/driver and avoid full-power impact driving, particularly in heavier gauge.
6) What size driver bit do I need for the Metallics JSTSP18 pan head screws?
A #2 Phillips bit is the specified driver size. The recess measures 0.169 to 0.182 in. diameter, 0.108 in. deep, with a 0.03 in. recess width, which is standard #2 geometry. A #1 bit will cam out and chew the recess on stainless.
7) Do these Metallics tapping screws meet ASME dimensional standards for inspection submittals?
Head dimensions are built to ASME B18.6.3-2013 and the thread to ASME B18.6.4. Metallics notes that dimensions for #9 diameter screws fall outside ASME B18.6.4, but the JSTSP18 is a #8 diameter, so it is covered.
8) Is a 2 inch length of #8 tapping screw too long for mounting electrical boxes and conduit straps?
At 2 in. of length it is on the long side for strap and box work, where 3/4 in. to 1 in. is typical. The 2 in. run is useful when you are going through insulation, furring, or stacked panels into sheet metal behind. Metallics builds the JSTSP series for electrical, plumbing, and HVAC work, and shorter lengths in the same pan head stainless pattern are available by request.
