Metallics JDWSR5C 6 x 2 in. Bugle Head Square Drive Drywall Screws - Steel Black Phosphate - Coarse Threads - Each

That's exactly the application. The JDWSR5C is a #6 x 2 inch coarse thread drywall screw with a sharp point, rated by Metallics for drywall-to-wood work. Coarse UNC threads bite into wood framing; the sharp point starts without pre-drilling. For drywall over steel studs you want a fine thread, self-drilling point screw instead.

A #1 square (Robertson) bit. The recess measures 0.090 to 0.106 inch wide and 0.055 to 0.071 inch deep, so a #2 square bit will not seat. Square drive is the reason people pick these over Phillips drywall screws: the bit holds the screw on the driver and cams out far less when you are sinking the head.

Black phosphate is a dry interior finish, not a corrosion coating. The JDWSR5C is AISI 1018 steel with black phosphate, meant for interior drywall and wood work. On an exterior deck, a wet bathroom behind tile, or anywhere the screw will see moisture, use a coated or stainless exterior screw instead, or you will get rust bleed through the finish.

No. Metallics lists the JDWSR5C as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. If your spec carries a domestic sourcing requirement, this is not the screw for that package.

They ship in a jar of 100, which is the order minimum. The jar weighs 0.6 lbs and measures 3 x 3.6 x 3 inches, so it drops into a tool bag or a van bin without repacking.

That is what the bugle profile does. The head is 0.315 to 0.347 inch across with a height of only 0.020 to 0.031 inch, so the underside flares gradually and compresses the paper into a shallow dimple rather than cutting it. Set it just below the surface and mud over. Note Metallics states there is no single industry standard for bugle head dimensions, so slight deviations between lots are normal.

The JDWSR5C is heat treated to Rockwell C45-64. That hardness is what lets the point self-start in wood framing and keeps the square recess from rounding out. The tradeoff with any hardened drywall screw is brittleness in shear, so they are for holding board to framing, not for structural or hanging loads.

8 to 10 threads per inch, UNC coarse. Wider thread spacing means fewer turns to set the screw and a deeper bite in softwood framing, which is why coarse is the standard choice for wood studs. Fine thread drywall screws run a much tighter pitch and are meant for light gauge steel.

Yes. The DWSR series runs other diameters, lengths and pack quantities beyond the #6 x 2 inch jar of 100, available by request. If you are standardizing a maintenance stock across several crews, specify the length and count you need rather than ordering around what a single jar size covers.
