Metallics DWC5B 6 x 2 in. Bugle Head Phillips Drywall Screws - Steel Black Phosphate - Coarse Threads - Each

Coarse thread, which is the wood stud version. The DWC5B runs 8 to 10 threads per inch in a UNC coarse spacing with a sharp point, so it bites into wood framing without pre-drilling. For hanging board on steel studs you want a fine thread with a drill or needle point instead, not this screw.

No. Black phosphate is a dry interior coating, and the DWC5B is a steel black phosphate screw meant for inside work. Exterior decks, wet rooms, or anything exposed to weather needs a coated or stainless exterior screw. Keep these on interior board, wood-to-wood, and cabinet work.

No on both counts. The DWC5B is not Buy American compliant and is not ARRA compliant, with a multiple-country origin. If your contract carries a domestic sourcing clause, this screw will not satisfy it.

A #2 Phillips. The recess is a Phillips drive sized for a #2 bit, with a recess depth of 0.106 in. and a recess diameter of 0.176 to 0.201 in. Three power bits ship in the box, so you have spares when the first one cams out.

That is what the bugle profile is for. The head measures 0.315 to 0.347 in. across with a head height of only 0.020 to 0.031 in., so the flare seats the head flush and slightly dimpled below the face without cutting the paper, ready for mud. Run a depth-setting nose on the gun and let the bugle do the work.

They ship as a box of 3,500 pieces, which is also the order minimum. The box weighs 19.29 lbs. Sized for a crew working a full floor rather than a single-room patch.

The DWC5B is heat treated to Rockwell C45-64 from AISI 1018 steel, which is the normal hardened range for a gun-driven drywall screw. That hardness resists cam-out and head twist-off at collated-gun speeds, but it also means the screw is brittle in shear, so don't use it as a structural fastener for framing or hanging loads.

They cover more than board. Metallics lists the DWC5B for wood-to-wood, drywall-to-wood, and cabinet installations, plus the electrical, plumbing, heating, and air conditioning trades. The #6 x 2 in. coarse thread suits mounting light-duty devices and backing to wood framing. It is not rated for structural or load-bearing anchorage.

Treat them as a guide. Metallics states there is no single industry standard for bugle head or drywall screw dimensions, so the 0.315 to 0.347 in. head width, 0.020 to 0.031 in. head height, and 8 to 10 threads per inch are published as ranges and minor deviation is acceptable. If you are matching an existing spec exactly, go by the ranges rather than a single number.
