.275″ x 4-1/2″ Heavy-Duty Structural Wood Screw with T-30 Drive

With its extended 4-1/2″ length and robust .275″ diameter, this structural screw penetrates deeply into dimensional lumber and engineered wood, creating secure load-bearing connections. The aggressive self-tapping thread design reduces installation time while maintaining dependable holding power in dense materials.

Key Features

• 4-1/2″ Extended Length: Provides deeper embedment for thicker structural members.
• .275″ Structural Diameter: Built for high-strength wood-to-wood connections.
• T-30 Star Drive: Improves torque transfer and reduces cam-out under load.
• Self-Tapping Threads: Designed to eliminate predrilling in most wood applications.

Common Applications

• Deck Ledger Installation: Secures ledgers to structural framing members.
• Beam-to-Post Connections: Reinforces load-bearing wood assemblies.
• Structural Blocking: Strengthens framing between joists and studs.
• Pergolas and Outdoor Structures: Ideal for heavy-duty exterior builds.
• Remodeling and Reinforcement: Adds strength to existing wood framing.

Installation Tips
