Metallics JSTSP37 – Frequently Asked Questions

1) Do I need to pre-drill a pilot hole for Metallics #8 x 3/8 in. Type A tapping screws?
A Type A tapping screw cuts its own thread as it drives, so the gimlet point lets it start in sheet metal or aluminum without a separate tapping step. In practice you still want a clearance hole in the top piece and a properly sized hole in the sheet you are threading into; the screw forms the thread, it does not drill the hole. Metallics lists the point as a gimlet point and the thread as 15 threads per inch.
2) Can I use these on a Buy American or ARRA-funded project?
No. The JSTSP37 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For federally funded work carrying domestic sourcing requirements you will need a domestically produced fastener instead.
3) What size Phillips bit drives these #8 pan head tapping screws?
A #2 Phillips bit. The recess is 0.169 to 0.182 inch in diameter at 0.108 inch deep, which is standard #2 geometry, so one bit covers the whole run. Keep the driver square and the torque moderate: minimum torsional strength is 39 lb-in, and stainless screws in that range will twist off before they strip the hole if you lean on an impact driver.
4) Are these stainless tapping screws OK for outdoor or damp locations?
18-8 stainless is the usual choice for wet and washdown areas, exterior enclosures, and coastal-adjacent work where plated carbon steel screws rust out. That is the material here. In chloride-heavy environments 18-8 can still pit over time, but for general outdoor electrical, plumbing, and HVAC service it is the corrosion-resistant option.
5) How much head does the pan head add above the surface, and will it clear a cover plate?
Head height runs 0.105 to 0.115 inch with a head width of 0.306 to 0.322 inch. That is a low rounded profile with a broad bearing surface, good for holding straps and thin plate, but it does sit proud of the surface. If you need the fastener flush in a countersunk hole, a pan head is the wrong head type, go to a flat head.
6) Do these screws meet a published dimensional standard for spec work?
Yes. Dimensions are to ASME B18.6.3-2013 and the thread is to ASME B18.6.4, so head and recess geometry are interchangeable with any other screw built to those standards. That matters if a submittal or a facility standard calls out an ASME dimensional spec rather than a brand.
7) What is the difference between a Type A tapping screw and a self-drilling screw for sheet metal work?
A Type A screw like the JSTSP37 has a sharp gimlet point and a coarse spaced thread for thin sheet, and it needs a hole to start in. A self-drilling screw has a drill point that makes its own hole in one pass, which is faster on steel studs or heavier gauge. For thin enclosure sheet, straps, and clips where you already have a punched or drilled hole, Type A gives cleaner thread engagement and less chance of over-drilling.
8) How do these Metallics tapping screws come packaged and what is the minimum order?
They ship in a jar, 100 pieces, which is the order minimum. Jar weight is listed at 0.19 lbs. For a large panel build or a multi-unit retrofit, order in multiples of 100.
