Metallics DWS9V 8 x 3 in. Bugle Head Phillips Drywall Screws - Steel Black Phosphate - Fine Threads - Each

Fine thread, sharp point drywall screws are the metal stud screw. The DWS9V runs 15 threads per inch with fine thread spacing and a sharp point, which bites into light gauge steel framing without stripping. For wood framing you want a coarse thread drywall screw instead, since coarse threads hold better in lumber.

A 3 inch length is for layered or thick assemblies, not a single sheet. The DWS9V is a #8 diameter, 3 inch screw, which suits double layer 5/8 board, board over existing wall surface, or fastening thick material back through drywall into framing. For a single 1/2 or 5/8 sheet on steel studs, a 1 or 1-1/4 inch fine thread screw is the normal choice and a 3 inch screw would overshoot the stud cavity.

No. The DWS9V is AISI 1018 steel with a black phosphate finish, which is a dry interior coating that resists handling corrosion but not moisture. Keep it to interior drywall work. For exterior sheathing, wet areas, or cement board outdoors, use a coated or stainless exterior rated screw.

A #2 Phillips bit. The recess is a Phillips drive with a 0.124 in. recess depth and 0.176 to 0.201 in. recess diameter, which is standard #2 geometry. Use a fresh bit and a depth setting nose cone so the bugle head seats flush without tearing the paper face.

That is what the bugle head is for. The DWS9V head measures 0.315 to 0.363 in. across with a head height of 0.020 to 0.039 in., so the tapered underside pulls the paper down and dimples it rather than cutting it, leaving a shallow depression you can fill with compound.

The DWS9V ships as a box of 500 count, and 500 is the order minimum. Box weight is listed at 5.43 lbs. Other sizes and quantities are available by request.

They are heat treated to Rockwell C44, which is the hardness range drywall screws are case hardened to so the sharp point drills light gauge steel without the shank twisting off. Back the clutch off on your screw gun and let the point do the work; over-torquing at the end of the drive is what breaks heads, not the stud itself.

The Metallics DWS9V is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so if your contract requires a specific origin certification on the lot you receive, request it with the order.

No, and that matters if you are matching a spec sheet. There is no single industry standard for bugle heads or for drywall screw dimensions generally, so the published figures on the DWS9V (15 TPI, UNF fine thread, head width 0.315 to 0.363 in.) are a guide and slight deviations between production lots are acceptable.
