Metallics JTS44 7 x 1 in. Pan Head Phillips Sharp Point Tapping Screws - Steel Zinc - Each

No. The JTS44 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded or domestic-preference job, these won't satisfy the sourcing clause.

The Metallics JTS44 is a Type A tapping screw, meaning a coarse 16 threads per inch with a gimlet (sharp) point that cuts its own thread into sheet metal, thin steel, or wood-backed material in a pre-punched or pilot hole. It does not drill its own hole, so it's not a substitute for a self-drilling (TEK) screw into unpunched steel. Type A's coarse pitch and spaced threads clear chips in thin stock; finer-pitch Type AB or B threads are the choice in heavier gauge.

A #2 Phillips bit. The recess is 0.163 to 0.176 inch in diameter, 0.1 inch deep, with a 0.029 inch recess width, which is standard #2 Phillips geometry. Torsional strength is 30 lb-in minimum, so back off the clutch on an impact driver if you're running these into steel studs or you'll snap heads.

Head height runs 0.096 to 0.106 inch, with a head width of 0.281 to 0.296 inch. A pan head seats flat on the surface rather than countersinking, so budget roughly a tenth of an inch of standoff. If you need the head flush or below the surface, a pan head is the wrong profile.

They're carbon steel with a zinc finish, which handles dry interior and lightly protected locations. Zinc plating is a sacrificial coating, not a marine or sustained-wet finish, so for exterior exposure, coastal air, or anything in standing moisture, go to stainless.

Head and recess dimensions follow ASME B18.6.3-2013, and the thread form follows ASME B18.6.4. Steel is AISI 1016 to 1024 case hardened to Rockwell C28 to 38, with 30 lb-in minimum torsional strength. Worth noting for anyone cross-checking a submittal: Metallics states that dimensions for the #9 diameter are independent of ASME B18.6.4.

At 1 inch of overall screw length with threads running the full shank, the JTS44 gives plenty of bite through a single sheet of metal or a box ear into a stud or wood blocking. Where it falls short is thick build-up: subtract the material you're clamping through, and you want at least three threads engaged in the holding member. For stacked plywood or a thick nailer, step up in length.

They ship in a jar of 100, and 100 is the order minimum, so you're buying a full jar rather than loose count. The jar is 3 x 3 x 2.15 inches and weighs 0.48 lbs, which drops into a van bin or a tool bag pocket without repacking.

Yes. The JTS44 is the #7 diameter by 1 inch pan head Phillips version, and Metallics offers other diameters, lengths and pack quantities in the JTS series by request.
