Metallics JTSS29 – Frequently Asked Questions

1) What size square driver bit do I need for the Metallics JTSS29 tapping screws?
A #2 square (Robertson) bit, listed as driver size 2R. The recess measures 0.112 inch across flats with a gaging depth of 0.060 to 0.075 inch, so a worn or undersized bit will cam out under load. Keep a couple of fresh #2 square bits in the pouch if you're driving a full jar.
2) Do Type A tapping screws like the JTSS29 need a pilot hole, or do they drill their own?
They need a pilot hole. The JTSS29 is a Type A tapping screw with a gimlet point, meaning it forms its own thread in sheet metal or a pre-drilled hole but has no drill flute to cut through material on its own. For thicker stock, drill first; in thin sheet the gimlet point will start in a punched hole.
3) Are Metallics JTSS29 screws Buy American or ARRA compliant for a government job?
No. The JTSS29 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing requirement, this part will not satisfy it.
4) How many Metallics JTSS29 screws come in a jar and can I buy fewer?
They ship in a jar of 100, and 100 is the order minimum. If you need a different size or count, Metallics offers other sizes and quantities by request.
5) Will a #10 pan head square drive screw sit flat against a panel or box flange?
Yes, it bears on the surface rather than countersinking. The pan head runs 0.357 to 0.373 inch across and 0.122 to 0.133 inch high, so it leaves roughly an eighth of an inch standing proud. If you need the head flush with the surface, you want a flat head screw in a countersunk hole instead.
6) Are these screws strong enough to drive with an impact driver without snapping the head off?
Torsional strength is rated at 48 lb-in minimum, with case hardness of Rockwell C28-38 on AISI 1016-1024 steel. That is the standard tapping screw window, but 48 lb-in is low for an impact driver, so a clutched drill-driver on a moderate setting is the safer tool.
7) Is zinc plated steel okay for outdoor or damp locations?
The JTSS29 is steel with a zinc finish, which is a dry-location and light-duty plating. It is fine inside panels, boxes, ductwork and mechanical rooms, but for exterior, wet or corrosive locations you want stainless.
8) What is the thread count on a #10 Metallics tapping screw?
12 threads per inch, built to the ASME B18.6.4 thread standard with head dimensions to ASME B18.6.3-2013. That matters if you're re-driving into an existing tapped hole, because a mismatched pitch will strip it.
9) What trades use the Metallics JTSS series tapping screws?
Metallics lists the JTSS square drive tapping screws for the electrical, plumbing, heating and air conditioning industries. In practice that is panel and enclosure work, strut and bracket attachment, duct and equipment mounting, and anything where a square recess beats a Phillips for one-handed overhead driving.
