The Simpson Strong-Tie® Strong-Drive® SDCP Timber-CP Screw is built to handle tough wood-to-wood connections in interior projects. Designed for engineered wood and mass timber construction, these screws offer serious strength while still being easy to install.

Each screw features a countersunk head that sits flush with the surface, giving your project a clean, professional look. The fully threaded shank provides excellent holding power, while the sharp point starts fast and drives smooth with less risk of splitting. Finished with a yellow-zinc coating, these screws are ideal for interior, dry applications where durability counts.
