Metallics JDWC5C 6 x 2 in. Bugle Head Phillips Drywall Screws - Steel Black Phosphate - Coarse Threads - Each

Coarse thread, sharp point screws are the wood stud choice. The JDWC5C is a #6 x 2 in. bugle head screw with coarse UNC threading at 8 to 10 threads per inch and a sharp point, so it bites and pulls into framing lumber. Metallics lists the application as wood to wood, drywall to wood and cabinet installations. For light gauge steel studs you want a fine thread (S-type) drywall screw instead, since coarse threads strip in sheet metal.

That is what the bugle head is for. The head measures 0.315 to 0.347 in. across with a head height of only 0.020 to 0.031 in., and the flared underside compresses the paper face rather than cutting it, so the head seats just below the surface and takes joint compound cleanly. Set the depth stop on your screw gun so the head dimples the board without breaking paper.

No. Black phosphate is a dry interior coating with minimal corrosion resistance, and these are built for interior board, cabinet and wood to wood work. For exterior decks, wet rooms or anywhere the fastener sees moisture, move to a coated or stainless exterior screw. The finish on these is listed as black phosphate over a steel body made to AISI 1018.

No. These are not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements you will need a domestically produced fastener instead.

A #2 Phillips bit. The recess is 0.106 in. deep and 0.176 to 0.201 in. across, which is standard #2 geometry, so a worn or undersized bit will cam out and chew the recess. Keep fresh #2 bits in the gun on a long board hang.

They come in a jar of 100, and the jar is the order minimum, so you buy in multiples of 100 pieces rather than individually. The packed jar weighs 0.6 lbs.

Case hardness runs Rockwell C45-64 on an AISI 1018 steel body, which is the normal heat treated range for drywall screws. That gives a hard point and recess that resists cam-out, but hardened screws are brittle in shear, so they are fasteners for board and trim attachment, not for structural or load bearing connections.

Metallics puts the JDWC and DWC series in its electrical line because the trades use them constantly for mounting: securing boxes, straps, backer blocks and panels to wood. The listed field applications cover the electrical, plumbing, and heating and air conditioning industries alongside drywall and cabinet work, and a 2 inch length gives enough reach to catch framing through sheathing or furring.

Treat them as a guide. There is no single industry standard for drywall screw or bugle head dimensions, and Metallics publishes the head width of 0.315 to 0.347 in. and head height of 0.020 to 0.031 in. as ranges, with slight deviations acceptable. The hard identifiers to order against are the #6 x 2 in. size, coarse thread, Phillips bugle head, and part number JDWC5C.
