Features & Benefits

• Collated Design – Engineered for rapid, continuous feeding with auto-feed screwdrivers, dramatically increasing installation speed on large projects.
• Coarse Thread Profile – Provides strong holding power in wood studs while allowing fast driving with minimal splitting.
• Black Phosphate Coating – Acts as a lubricant for smoother driving and offers good indoor corrosion resistance.
• Bugle Head – Wide bearing surface pulls drywall tightly against framing without damaging the face paper.
• PH2 Drive – Optimized for high-torque, high-speed applications with excellent bit retention.
• Dual Diameter Range – 3.5 mm for standard boards and 4.2 mm for thicker materials requiring extra length and strength.

Typical Applications

• High-volume fixing of gypsum board, plasterboard, and ceiling panels to timber studs and battens
• Commercial and residential drywall installation, partitions, and suspended ceilings
• Fire-rated, moisture-resistant, and acoustic board installations
• Ideal for contractors using collated screw systems (e.g. drywall screw guns)
