Metallics JTSS7 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JTSS7 square drive screws?
A #2 square (Robertson) bit. The JTSS7 is specified for driver size 2R, with a recess measuring 0.112 across the flats and a gaging depth of 0.060 to 0.075 inch. A #1 bit will cam out and round the recess; a #3 will not seat.
2) Will a #8 x 1/2 in. Type A tapping screw hold in sheet metal without a tapped hole?
Yes, that is what a Type A tapping screw is for. The JTSS7 has a gimlet point and 15 threads per inch, so it cuts its own thread in a pilot-drilled or punched hole in sheet metal. It is not a self-drilling screw, so you still need a hole started.
3) Do Metallics JTSS7 screws qualify for a Buy American or ARRA job?
No. The JTSS7 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. On a federally funded project with domestic sourcing requirements you will need a domestically manufactured tapping screw instead.
4) Are these screws OK for mounting devices and straps inside electrical boxes and enclosures?
That is the intended use. Metallics lists the JTSS7 for the electrical, plumbing, heating and air conditioning trades, and the pan head sits flat against sheet metal with a broad bearing surface (head width 0.306 to 0.322 in., head height 0.105 to 0.115 in.) without needing a countersink.
5) How many screws come in a jar of Metallics JTSS7?
They ship 100 to a jar, and 100 is the order minimum. The jar weighs 0.38 lbs.
6) Will these zinc plated screws hold up outdoors or in a damp location?
The JTSS7 is carbon steel with a zinc plating, which is a mild indoor corrosion finish. It is fine in conditioned interior work, panel and enclosure work, and dry mechanical rooms. For wet, exterior, coastal or chemically aggressive locations, specify a stainless or hot dip galvanized tapping screw instead.
7) What standards do the Metallics JTSS7 screws meet?
Head and recess dimensions follow ASME B18.6.3-2013, and the thread is to ASME B18.6.4. The steel is AISI 1016 to 1024, case hardened to Rockwell C28-38, with a minimum torsional strength of 39 lb-in.
8) Can I run these in with an impact driver without snapping them?
They are rated to a minimum torsional strength of 39 lb-in and hardened to Rockwell C28-38, which is normal for a #8 Type A screw. That is a low ceiling for an impact driver, so set a clutch or use a drill on low torque. The square recess helps because it resists cam-out better than a Phillips of the same size.
