Metallics JTSS3 – Frequently Asked Questions
1) What driver bit do I need for the Metallics JTSS3 square drive tapping screws?
A #1 square (Robertson) bit. The JTSS3 uses a square recess sized 1R, with a recess width across flats of 0.091 in. and a gaging depth of 0.050 to 0.065 in. Stock a couple of spare #1 bits if you are running a full jar of 100.
2) Is the JTSS3 a self-tapping screw for sheet metal, and does it need a pilot hole?
It is a Type A tapping screw with a gimlet point, which is the sharp-point style made to cut its own thread in thin sheet metal, boxes, straps and light gauge steel. Type A screws are normally run into a pilot hole sized for the gauge you are fastening; the point starts easily but it is not a drill point, so it will not self-drill through heavier stock.
3) Will a #6 pan head screw snap when driven with an impact driver?
The JTSS3 is rated to a 24 lb-in minimum torsional strength and case hardened to Rockwell C28-38. That is plenty for hand driving or a clutched screwgun, but a #6 shank at 24 lb-in will twist off if you lean on an impact driver. Set a low clutch and stop when the head seats.
4) Can I use Metallics JTSS3 screws on a Buy American or ARRA funded job?
No. The JTSS3 is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements you will need a domestically produced tapping screw instead.
5) What size and thread count are the Metallics JTSS3 tapping screws?
#6 diameter by 1 inch long, with 18 threads per inch. The pan head measures 0.256 to 0.270 in. across and 0.087 to 0.097 in. high, so it sits low and wide enough to hold thin sheet without pulling through.
6) Are these zinc tapping screws suitable for outdoor or damp locations?
These are steel with a zinc finish, which is an indoor and dry-location plating. Zinc gives mild corrosion resistance for interior electrical, plumbing and HVAC work, not for exterior exposure, wet locations or coastal air. For those, specify a stainless or hot dip galvanized tapping screw instead.
7) Do the Metallics JTSS3 screws meet a dimensional spec I can put on a submittal?
Yes. Head and recess dimensions are to ASME B18.6.3-2013, the thread form is to ASME B18.6.4, and the steel is AISI 1016 to 1024. Those three plus the 24 lb-in torsional minimum are what a spec reviewer normally wants on a tapping screw submittal.
8) How do the JTSS3 tapping screws come packaged and what is the minimum order?
They ship in a jar of 100 pieces, and 100 is the minimum order quantity. The jar weighs 0.4 lbs. Metallics offers other sizes and quantities in this square drive pan head tapping screw line by request.
