Metallics JSDS6C 7 x 2 in. Bugle Head Phillips Drywall Screws - Steel Zinc - Fine Threads - Each

Yes. The JSDS6C is a self-drilling and tapping drywall screw with a drill point, so it cuts its own hole through light gauge metal framing and taps as it goes. No pilot hole needed. The fine thread and drill point combination is the metal stud setup, not the wood one.

Fine thread for steel studs, coarse for wood. The JSDS6C is the fine thread version (UNF), with a drill point that pierces the stud. If you are hanging board on wood framing, a coarse thread sharp point screw holds better in the wood fiber and you should not use this one.

The JSDS6C is flagged compliant for both ARRA and Buy American. Country of origin is listed as multiple, so if your specification requires a single documented origin, request that confirmation against the lot you are issued.

A #2 Phillips bit. That is the stated driver size for the JSDS6C, and it is the standard bit for drywall screw guns, so the same bit covers the rest of the run.

The bugle head has a curved underside that compresses the paper face as it seats instead of tearing it, so the screw sinks just below flush and takes joint compound cleanly. A flat or pan head would cut the facing or stand proud and telegraph through the finish. The JSDS6C uses the bugle profile with a Phillips drive.

The JSDS6C ships in a jar with a 100 count order minimum, so you are buying by the 100-piece jar rather than by the individual screw. The packed jar weighs 0.65 lbs.

The JSDS6C is case hardened to Rockwell C44 and made from AISI 1018 steel, which is what lets the drill point cut light gauge steel rather than spin out. That hardness is also why you want steady gun pressure and a clutch set to depth; over-driving a hardened screw is how heads pop off.

Zinc plating on steel is a mild corrosion coating meant for dry interior work, and the JSDS6C is a steel zinc interior drywall fastener. For exterior sheathing, tile backer in wet areas, or treated lumber, go to a fastener rated for that exposure instead.

Close, but not to a hard tolerance. There is no single industry standard for drywall screw dimensions or for bugle head geometry, so Metallics publishes the #7 diameter, 2 inch length figures as a guide and slight deviations are acceptable. If your submittal needs an exact head diameter or thread pitch, work from the dimensional guide rather than treating the numbers as a tight spec.

Yes. The JSDS6C sits in the Metallics SDS and SDSB series of bugle head Phillips self-drilling and tapping drywall screws, and other sizes and pack quantities in the family can be had by request if 7 x 2 inch in a 100 count jar is not the size you need.
