Metallics JTSS8 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JTSS8 square drive tapping screws?
A #2 square (Robertson) bit. The spec calls out driver size 2R, with a recess measuring 0.112 across the flats and a gaging depth of 0.060 to 0.075 inch. Using a #1 bit will cam out and using a #3 will not seat, so keep a #2 square bit in the gun.
2) Will a #8 x 3/4 in. Type A tapping screw cut its own threads in sheet metal, or do I need to pre-tap?
No tapping needed. The JTSS8 is a Type A tapping screw with a gimlet point, so it forms its own thread in a drilled or punched pilot hole in sheet metal. It has 15 threads per inch and the thread conforms to ASME B18.6.4. It is not a self-drilling screw, so you still need a pilot hole.
3) Do Metallics JTSS8 screws qualify for a Buy American or ARRA funded job?
No. The JTSS8 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a federally funded project with domestic sourcing language, specify a domestic fastener instead.
4) Is a zinc plated steel tapping screw OK for outdoor or damp locations?
Zinc plating on the JTSS8 is a mild corrosion coating meant for dry indoor electrical, plumbing and HVAC work. The material is carbon steel in the AISI 1016 to 1024 range with a zinc finish. For wet, coastal or exterior exposure, buy a stainless fastener instead.
5) How much torque will these #8 tapping screws take before the head twists off?
39 lb-in minimum torsional strength, with the screws hardened to Rockwell C28-38. That is enough for driving into duct, panel enclosures and strut with a clutched driver, but set the clutch rather than running an impact wide open, since a #8 shank snaps well before an impact reaches its rated torque.
6) How is the JTSS8 packaged and what is the minimum I can buy?
These ship in a jar of 100 screws, and 100 is the order minimum. Jar weight comes in at 0.49 lbs.
7) What are these #8 square drive tapping screws normally used for on a job?
They are a sheet metal fastener for the electrical, plumbing and HVAC trades: hanging device boxes and covers, fastening duct and plenum sheet, securing straps and brackets to panel steel. The square recess is the reason tradesmen pick them, the bit sticks in the screw so you can drive one-handed overhead. Head is a pan, which is what you want for a flush-bearing surface on flat stock rather than a countersunk hole.
