Metallics JTSF57 – Frequently Asked Questions

1) What is a Type A tapping screw used for, and will the Metallics JTSF57 cut its own threads in sheet metal?
The Metallics JTSF57 is a Type A tapping screw with a gimlet point, so it forms its own thread as it drives into thin sheet metal, sheet steel boxes, and similar light-gauge material from a pilot hole. It is a #14 diameter screw, 3/4 inch long, with 10 threads per inch. No separate nut or tapped hole is needed. For thicker steel or structural material, a Type A screw is the wrong choice.
2) What size Phillips driver bit do I need for the Metallics JTSF57 #14 tapping screw?
Use a #3 Phillips bit. The recess on this #14 flat head screw measures 0.276 inch in diameter and 0.16 inch deep, which is larger than a #2 bit seats properly in, and a #2 will cam out and strip the recess under the 125 lb-in minimum torque this screw is rated to take.
3) Are these screws Buy American and ARRA compliant for a government or institutional job?
The JTSF57 is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so if your contract requires a single named country of manufacture on the submittal, confirm the origin on the lot you receive.
4) Do these Metallics JTSF screws meet a dimensional standard for spec work?
The JTSF57 is built to ASME B18.6.4-1998 for dimensions and ASME B18.6.4 for threads, with material to AISI 1016-1024 steel and a hardness of Rockwell C28-38. One caveat on the series: dimensions for the #9 diameter are independent of ASME B18.6.4. The #14 size is covered.
5) Is a zinc plated steel tapping screw suitable for outdoor or damp locations?
The JTSF57 is zinc plated carbon steel, which is a dry-interior finish. It handles normal indoor electrical and MRO work, but zinc on steel will corrode in weather exposure, wash-down areas, or coastal air. For exterior or wet locations, specify a stainless or hot-dip galvanized tapping screw instead.
6) How much torque can a #14 zinc tapping screw take before it snaps in a power driver?
Minimum torsional strength on this screw is 125 lb-in. With a #3 Phillips bit seated square, that is the ceiling to set a clutch or impact driver below. Driving at full impact into heavier material than a Type A point is meant for is what shears these heads off.
7) How do these Metallics tapping screws come packaged and what is the minimum order?
They ship in a jar of 100, and 100 count is the order minimum. The jar weighs 0.87 lbs. That is the unit to plan around if you are stocking a truck or a shop crib rather than buying bulk boxes.
8) What thread gaging diameter do these #14 tapping screws run, for checking against a pilot hole?
Gaging diameter on the JTSF57 is 0.41 inch, with protrusion above the gaging diameter of 0.029 to 0.049 inch. With 10 threads per inch, that gives you the numbers to size a pilot in sheet metal rather than guessing and splitting the material.
