Metallics JTS13 6 x 5/8 in. Pan Head Combo Sharp Point Tapping Screws - Steel Zinc - Each

The JTS13 has a gimlet point, which is the sharp, pointed Type A style meant to start on its own in thin sheet metal, sheet metal boxes, and similar light gauge material. The 18 threads per inch coarse thread is what gives it bite in sheet. In harder or thicker stock a pilot hole is still the right call, because this is a thread-forming screw and not a self-drilling screw with a cutting tip.

Head width on the JTS13 runs 0.256 to 0.27 in. and head height 0.087 to 0.097 in., so it is a low profile #6 pan head that seats flat against a box tab or strap without standing proud. The head conforms to ASME B18.6.3-2013 dimensional standard, so it interchanges with any other standard #6 pan head.

No. The JTS13 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your spec carries a domestic sourcing requirement, this screw will not satisfy it.

A #2 Phillips bit drives the JTS13. The pan head carries a combination recess, both Phillips and slotted, so a flat blade works too if you are hand-driving in a tight spot. Phillips recess diameter is 0.159 in., slot width 0.039 to 0.048 in. and slot depth 0.033 to 0.05 in.

Zinc plated carbon steel, so the JTS13 is a dry or indoor-location fastener. The plating resists handling corrosion and incidental moisture, but for wet, coastal, or exterior work you want stainless rather than zinc plated steel.

They ship 100 to a jar, and 100 is the order minimum. The filled jar weighs 0.28 lbs.

Minimum torsional strength is 24 lb-in, with the steel heat treated to Rockwell C28-38 hardness per AISI 1016-1024 material. That is enough for hand or low-torque driver work in sheet metal, but 24 lb-in is not much headroom on an impact driver. Run it on a clutch-set drill driver and you will not snap heads.

The thread follows ASME B18.6.4 at 18 threads per inch in the #6 diameter, which is the standard Type A tapping screw thread. It will re-enter a hole already formed by any other standard #6 Type A screw.

The JTS13 is intended for electrical, plumbing, heating and air conditioning work: fastening into sheet metal boxes, straps, duct, panel covers, and light gauge brackets. The combination Phillips and slotted head is the usual choice on a service truck because either driver in the pouch will turn it.
