Metallics DWSR4B – Frequently Asked Questions

1) What driver bit do I need for the Metallics DWSR4B square drive drywall screws?
A #1 square (Robertson) bit. The recess is square drive, 0.090 to 0.106 in. wide and 0.055 to 0.071 in. deep, so a #1 seats fully and keeps cam-out down when you are running a few thousand of them on a screw gun.
2) How many screws come in a box of DWSR4B, and can I buy fewer?
They ship as a box of 5,000 each, which is the order minimum on this item. If you need a smaller count or a different length, Metallics offers other sizes and quantities by request.
3) Is the black phosphate finish on these drywall screws OK for exterior or damp work?
No. Black phosphate is a dry interior coating, not a corrosion barrier. The DWSR4B is a steel screw with a black phosphate finish, which keeps it from flash rusting in the box and takes joint compound and paint well, but it will corrode in wet or exterior exposure. For a deck, a soffit, or anything seeing moisture, use a coated or stainless exterior screw instead.
4) Are Metallics DWSR4B drywall screws Buy American or ARRA compliant for a government job?
No. The DWSR4B is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries a domestic sourcing clause, this item will not satisfy it.
5) Will the bugle head sink flush without tearing the drywall paper?
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 tapered underside compresses the facing instead of cutting it and sits just below the surface for mud. Set your gun depth and let the clutch stop it rather than driving on torque.
6) How hard are these screws, and will the heads snap off when I drive them?
They are case hardened to Rockwell C45-64 from AISI 1018 steel, so the recess and threads hold up to repeated gun driving. That hardness also means they are brittle rather than ductile, which is normal for drywall screws. They are not structural fasteners and should not be used where shear loading matters.
7) Should I expect the head and thread dimensions to match another brand's drywall screw exactly?
Close, but not identical. There is no single industry standard for drywall screw or bugle head dimensions, so Metallics publishes the figures (head 0.315 to 0.347 in. wide, 8 to 10 TPI) as a guide and slight deviations are normal. For a mixed-brand job it matters mainly for driver bit fit, and a #1 square bit covers these.
8) What is the thread pitch on the Metallics DWSR coarse drywall screws?
8 to 10 threads per inch, UNC coarse spacing. The wide pitch is what pulls board tight to wood framing in fewer turns; a fine thread drywall screw runs far higher TPI and is intended for light gauge metal studs.
9) Do these screws need a pilot hole in wood framing?
No pilot hole. The DWSR4B has a sharp point that self-pierces the drywall facing and starts in wood framing on its own. Just keep the gun square to the board so the point does not walk.
10) How much does a 5,000 count box of these 1-5/8 in. drywall screws weigh?
About 26 lbs for the box. Worth knowing if you are staging material on a floor by hand or ordering several boxes per unit on a multi-family build.
