Metallics JTSS32 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JTSS32 square drive tapping screws?
A #2 square (Robertson) bit. The JTSS32 is specified for driver size 2R, and the recess measures 0.112 across flats with a gaging depth of 0.060 to 0.075 inch. Square recess holds the bit without cam-out, which is why these are common on overhead electrical work where you only have one hand free.
2) Will a #10 x 2-1/2 in. Type A tapping screw bite into wood studs and sheet metal without a pilot hole?
The JTSS32 is a Type A tapping screw with a gimlet point, so it starts its own hole in wood and thin sheet metal. The 12 threads per inch, coarse spacing is what lets it cut rather than just displace. In heavier gauge steel you still want a pilot hole, since a gimlet point is a wood/light-gauge point, not a drill point.
3) Will a pan head screw sit flush, or do I need a flat head for mounting straps and brackets?
Pan head sits on top of the surface, it does not sit flush. Head width runs 0.357 to 0.373 inch and head height 0.122 to 0.133 inch, so budget about an eighth of an inch of standoff. That wide bearing surface is what you want for clamping conduit straps, box brackets, and plates. If the fastener has to finish flush in a countersunk hole, use a flat head instead.
4) Can I use the Metallics JTSS32 screws on a federally funded job with domestic sourcing requirements?
No. These are not Buy American compliant and not ARRA compliant, and country of origin is multiple. On a project with domestic fastener requirements you need a US-made alternative.
5) How much torque can these #10 square drive screws take before the head strips?
48 lb-in minimum torsional strength, with the screw heat treated to Rockwell C28-38. That is the figure to watch if you are running them with an impact driver, set the clutch rather than driving to stall.
6) Are these zinc plated screws OK for outdoor or damp locations?
The JTSS32 is steel with a zinc finish, made from AISI 1016 to 1024 carbon steel. Zinc plating is an indoor and dry-location coating, it will corrode in sustained wet or coastal exposure. For wet locations, exterior walls, or anywhere subject to washdown, specify stainless or hot dip galvanized fasteners instead.
7) Do these screws meet a dimensional standard I can put on a submittal?
Yes. Head and recess dimensions are to ASME B18.6.3-2013 and the threads are to ASME B18.6.4, with material to AISI 1016 through 1024. Those are the citations to carry on a spec submittal for a #10 Type A tapping screw.
8) How are the Metallics JTSS32 tapping screws packaged, and what is the minimum I can buy?
They ship in a jar of 100, which is the order minimum. The jar runs 1.58 lbs and measures 3.5 x 3.5 x 5.75 inches, so it drops into a van bin or gang box tray without repacking.
