Phosphate Drywall Screws PH2 Cross Recess
Phosphate Drywall Screws PH2 Cross Recess
Secure gypsum boards, drywall sheets, wallboard, and interior timber framing with our Premium Black Phosphate Drywall Screws. Precision-manufactured from heat-treated hardened carbon steel (C1022A), these heavy-duty fasteners feature a smooth bugle head designed to countersink cleanly into drywall paper without tearing or weakening the surface.
Equipped with a standard #2 Phillips (PH2) cross drive recess, these screws ensure slip-free driving with power tools. The corrosion-resistant black phosphate surface finish provides superior paint and joint compound adhesion while protecting against rust in interior building environments.
Key Features
-
Countersinking Bugle Head: Depresses paper face neatly without damaging fragile gypsum cores, creating a flush surface for easy mudding and taping.
-
Corrosion-Resistant Black Phosphate Finish: Premium dark oxide coating prevents rust and serves as a high-adhesion primer base for joint compounds and paint.
-
Deep PH2 Cross Drive Recess: Precision-machined Phillips #2 drive minimizes bit slippage, cam-out, and screw head stripping during high-speed installation.
-
Sharp Needle Point: Pierces through drywall sheets, wooden studs, and light-gauge metal channels without requiring pre-drilling.
-
Hardened Carbon Steel Core: High tensile and torque strength resists snapping or shearing under power-driver pressure.
