Zinc-Plated Bugle Head Self-Drilling Screws – PH2 Phillips Drive Gypsum & Sheet Metal Tek Screws (Multi-Size Selection)
Zinc-Plated Bugle Head Self-Drilling Screws – PH2 Phillips Drive Gypsum & Sheet Metal Tek Screws (Multi-Size Selection)
Fasten drywall, cement boards, and composite sheet panels directly to heavy-gauge metal studs with our Zinc-Plated Bugle Head Self-Drilling Screws. Combining the smooth countersinking action of a bugle head with an integrated drill-bit point, these heavy-duty fasteners drill their own hole, tap mating threads, and seat flush in one fast, continuous operation—eliminating pre-drilling and pilot holes.
The smooth, curved bugle head depresses the surface material neatly without cracking or tearing the outer face paper, while the bright zinc-plated finish delivers enhanced corrosion resistance against moisture, humidity, and atmospheric wear compared to standard black oxide screws. Driven easily with a standard #2 Phillips driver bit, these screws are essential for framing, interior partition walls, and commercial cladding installations.
Key Features
-
Self-Drilling Drill Point (Tek Point): Pierces directly through heavy-gauge steel studs (up to 3.0 mm thick) without requiring pre-drilling.
-
Countersinking Bugle Head: Concave under-head transition depresses wallboard and panel surfaces smoothly to create a clean, flush finish for mudding and painting.
-
Corrosion-Resistant Zinc Plating: Bright clear-zinc coating protects the hardened steel core against rust and corrosion in damp or humid interior environments.
-
Deep PH2 Phillips Drive: Precision cross recess reduces bit slipping, cam-out, and screw head stripping during high-speed driving.
-
Hardened Carbon Steel Construction: Case-hardened core provides superior tensile and shear strength under high installation torque.
