Metallics JDWS4V 6 x 15/8 in. Bugle Head Phillips Drywall Screws - Steel Black Phosphate - Fine Threads - Each

Yes. At 1-5/8 inches the JDWS4V leaves roughly an inch of embedment behind 5/8 inch board, which is the standard length for single layer 5/8 inch gypsum on steel studs. It is also the usual choice for double layered 1/2 inch board. For single layer 1/2 inch drywall, a 1-1/4 inch screw is the more common pick.

No. Black phosphate on AISI 1018 steel is a mild corrosion and lubricity coating for interior dry use only, and it will rust in exposed or wet conditions. Keep the JDWS4V for interior gypsum board and specify a corrosion resistant fastener for exterior sheathing, cement board in wet areas, or anything exposed to weather.

A #2 Phillips. The recess is 0.176 to 0.201 inch in diameter and 0.106 inch deep, so a #2 tip seats fully; a #1 will cam out and chew the recess, and a #3 will not drop in.

That is what the bugle profile is for. The JDWS4V has a bugle head measuring 0.315 to 0.347 inch across with a head height of only 0.020 to 0.031 inch, so the curved underside compresses the gypsum and sets just below the face instead of cutting it. Set your driver depth stop so the head dimples the paper rather than breaking it.

They are heat treated to Rockwell C44, which is the normal case hardness range for drywall screws and is what lets the sharp point pierce light gauge steel stud without the shank twisting off. Run them at drywall gun speed and let the clutch set the depth; over-torquing any hardened screw is what breaks heads.

The JDWS4V is flagged compliant for both Buy American and ARRA, with country of origin recorded as multiple. If your spec requires a single named origin on the submittal, call that out on the order.

They ship in a jar with a 500 count minimum, and the packed jar weighs 5.03 lbs. Overall package footprint is 4.5 by 4.5 by 7.25 inches, so it stacks easily on a cart or in a gang box.

Yes. The DWS series bugle head Phillips drywall screws are offered in other diameters, lengths and quantities by request, so if you are standardizing a building on one screw but need a 1-1/4 or 2 inch length alongside the 6 x 1-5/8, ask for it rather than mixing brands.

Because there is no single industry standard for bugle head geometry or drywall screw dimensions. Metallics publishes the head width as 0.315 to 0.347 inch and the head height as 0.020 to 0.031 inch as a guide, and slight deviation inside that band is normal production tolerance, not a defect. It does not affect how the screw sets in gypsum board.
