Technical Features
- Star Drive Head: Provides increased bit engagement and reduced cam-out compared to Phillips-style drives, improving installation speed and control.
- W-Cut Thread Design: Cuts into substrate material as the screw is driven, reducing driving torque and minimizing the risk of wood splitting.
- Self-Drilling Point: Eliminates the need for pre-drilling pilot holes, reducing installation steps and improving on-site productivity.
- Bugle Head Profile: Distributes load across a wider surface area and countersinks smoothly without tearing substrate material, ideal for decking top boards and framing panels.
- Carbon Steel Construction with Polymer Plating: Provides structural fastening strength with a corrosion-resistant polymer coating suitable for both indoor and outdoor use.
- 9.8 TPI Thread Pitch: Optimized thread density for secure holding power in framing-grade lumber and engineered wood products.
- 70-Pack Clamshell Packaging: Convenient resealable format for jobsite storage and inventory management.
Applications
- Multi-purpose general framing and structural framing
