Metallics JTSP14 6 x 3/4 in. Pan Head Phillips Sharp Point Tapping Screws - Steel Zinc - Each

The JTSP14 is a #6 diameter by 3/4 inch long pan head tapping screw with a Phillips recess. Use a #2 Phillips bit. The head measures 0.256 to 0.27 inch across and 0.087 to 0.097 inch high, so it sits low enough to clear most cover plates and strap clamps.

A Type A screw like the JTSP14 has a gimlet (sharp) point and a coarse 18 threads per inch, so it bites into a pre-punched or pre-drilled hole in thin sheet metal, sheet steel boxes, and light gauge framing without needing a nut. It does not drill its own hole. If you are fastening into heavier gauge steel with no pilot, you want a self-drilling (Type TEK) point instead.

They ship in a jar of 100, and 100 count is the order minimum. The packed jar weighs 0.33 lbs.

The JTSP14 is carbon steel with a zinc plating, which is a mild indoor corrosion coating. It suits dry interior work such as boxes, straps, and raceway. For wet, exterior, or washdown locations, specify stainless steel tapping screws instead.

The JTSP14 is specified at 24 lb-in minimum torsional strength and case hardened to Rockwell C28-38, which is the normal spec range for a tapping screw of this diameter. That is enough for hand or clutch-driven installation, but a #6 screw will still twist off if you run an impact driver at full power. Set the clutch and seat the head rather than over-driving.

Yes. Head and recess dimensions follow ASME B18.6.3-2013, threads follow ASME B18.6.4, and the material is AISI 1016-1024 steel. Note that #9 diameter screws in the JTSP series are dimensioned independently of ASME B18.6.4, though that does not affect this #6 size.

The JTSP14 carries a C designation on both ARRA and Buy American compliance in the manufacturer data, with country of origin listed as China. On federally funded work, verify that designation against your project's specific domestic content requirement before submitting.

With a gimlet point and 18 TPI coarse thread, the #6 shank needs a punched or drilled pilot in thin sheet steel. The Phillips recess runs 0.153 to 0.166 inch in diameter at 0.091 inch deep with a 0.028 inch slot width, which is the standard #2 Phillips geometry. A worn bit will cam out of that recess before the screw seats, so start with a fresh #2.

The JTSP series runs beyond the #6 x 3/4 inch JTSP14, and other sizes and quantities are available by request. Pan head, Phillips drive, and zinc plated steel stay the same across the series.
