Detailed Product Overview

These professional-grade drywall fasteners are precision-manufactured from high-purity C1022A carbon steel to ensure high tensile rigidity and exceptional core stability under load. Designed primarily for securing drywall, plasterboard, and gypsum sheets to commercial steel framing, light steel keels, and interior lightweight walls, the screws feature a deep, uniform Phillips drive recess that maximizes bit grip and limits tool cam-out during rapid power driving. Technically, the smooth, concave bugle head structure is engineered to depress the paper surface of the drywall cleanly without tearing it, facilitating a flush, professional finish that simplifies subsequent mudding and taping workflows. Equipped with a precision-forged fine thread pattern and a dedicated self-drilling tail, these fasteners easily drill, tap, and firmly lock into multi-layer sheet arrangements with minimal installer exertion. Coated in a high-grade blue-white zinc plating that yields robust atmospheric protection and an attractive bright finish, these highly versatile ST3.5 to ST5.5 fasteners deliver an efficient, cost-effective, and long-lasting joining solution for commercial partition construction, suspended ceilings, and lightweight metal fastening tasks.

Key Features

• Smooth Concave Bugle Head: Depresses drywall and gypsum board surfaces precisely without cutting or tearing the outer paper face, enabling a clean, flush finish.

• Rigid C1022A Carbon Steel: Grade 8.8 case-hardened alloy provides exceptional torsional strength, preventing head snapping during high-speed installation.

• Bright Blue-White Zinc Shield: Premium galvanization layer guards against rust and environmental wear, keeping interior wall structures pristine.

• Integrated Self-Drilling Point: Precision cutting tip bites instantly into lightweight steel keels and tracks without walking or slipping.

• High-Torque Phillips Recess: Uniformly rolled deep cross drive ensures perfect screwdriver bit engagement and fluid torque transmission.
