Metallics JSTSP13 – Frequently Asked Questions

1) Do I need to pre-drill for Metallics #8 x 1/2 in. Type A tapping screws?
Type A tapping screws thread their own way in. The gimlet point on the Metallics JSTSP13 cuts into sheet metal or thin stock without a pilot hole in most cases, which is why they show up in panel and enclosure work. In heavier steel you'll still want a pilot to protect the screw, since torsional strength is rated at 39 lb-in minimum and over-torquing a #8 head snaps it.
2) Will 18-8 stainless tapping screws hold up in a damp or outdoor electrical enclosure?
18-8 stainless is the material on the JSTSP13, so corrosion resistance is far better than a plated carbon steel tapper in humid, washdown, or coastal-adjacent conditions. Stainless also avoids the galvanic problem you get running zinc-plated screws into aluminum enclosures, which matters given these are pointed at electrical, plumbing, and HVAC work.
3) Will a Metallics #8 x 1/2 in. tapping screw hold in thick steel, or is it for sheet metal only?
At 1/2 in. long, you get very little engagement once you allow for the head bearing and material thickness, so these are for sheet metal, thin plate, strut accessories, and enclosure hardware rather than structural or heavy plate work. Thread pitch is 15 per inch, which is what lets a short screw pick up enough turns in thin stock. For thicker assemblies step up to a longer screw in the same series.
4) Do Metallics JSTSP13 screws qualify for a Buy American or ARRA job?
No. These are flagged not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-content requirement on fasteners, these will not satisfy it and you need a domestically sourced screw instead.
5) What size driver bit do these Metallics pan head Phillips screws take?
A #2 Phillips. The recess is dimensioned at 0.169 to 0.182 in. diameter and 0.108 in. deep, so a standard #2 bit seats fully. Stainless cams out more readily than hardened steel, so use a sharp bit and steady pressure rather than high speed.
6) Are these screws made to a recognized dimensional standard for spec submittals?
Yes. The JSTSP13 is built to ASME B18.6.3-2013 for dimensions, with threads to ASME B18.6.4. That gives a submittal reviewer a named standard for head geometry, recess, and thread form instead of a house spec, which is usually what an institutional or government job wants on the fastener line.
7) Type A tapping screw vs. self-drilling Tek screw: which do I want for an electrical enclosure?
A Type A like the JSTSP13 has a gimlet point that forms threads but does not drill its own hole, so it suits thin sheet, soft aluminum, or an existing punched hole. A self-drilling screw carries a drill tip and is the one you reach for when you have to get through heavier gauge steel in one pass. For attaching accessories to a punched enclosure or panel, the Type A is the cleaner, less aggressive choice.
8) How are these tapping screws packaged and what is the minimum I can buy?
They come in a jar of 100, and 100 is the minimum order quantity. The jar weighs 0.39 lbs, so a service van can carry several sizes without much penalty. For repeat MRO stocking this is the practical unit; there is no smaller break.
9) Will these stainless screws work loose from vibration on HVAC equipment?
The 15 threads per inch pitch gives more thread engagement per inch of penetration than a coarse tapper, which helps resistance to backing out under vibration. On rotating or blower-mounted equipment, still pair them with a lock washer or thread locker if the assembly sees continuous vibration; thread pitch alone is not a locking feature.
