The Simpson Strong-Tie TFP1475S TF Wood-to-Steel Collated Screw with black phosphate coating is designed for rapid installation of wood sheathing, subflooring, or wood framing to cold-formed steel. These collated screws feature a flat head with nibs and a sharp point, optimized for high-speed, consistent driving with minimal installation torque.

Ideal for indoor structural applications, the black phosphate coating offers moderate corrosion resistance for dry service conditions. Designed for use with auto-feed systems, this collated screw streamlines installation and reduces labor costs in commercial framing, multifamily construction, and interior retrofit projects.

Key Features:

• Black phosphate coating for moderate corrosion resistance in dry interior environments
• Flat head with nibs provides clean countersinking into wood
• Sharp point and optimized thread design reduce driving torque
• Fully threaded for high withdrawal resistance
• Designed for collated auto-feed screw driving systems

Applications:

• Wood sheathing to steel framing
• Subfloor installation over steel joists
• Interior partition wall framing
• Light-gauge cold-formed steel connections in dry service areas

Installation Notes:

• For best results, use with Simpson Strong-Tie auto-feed screw driving systems or other compatible collated drivers
• Suitable for attaching wood to steel thicknesses from 18 to 14 gauge
• Ensure the screw is driven until the head is flush with the wood surface
• Pre-drilling is not typically required
