The Simpson PWKIT40T T40 Offset Driver-Bit Kit from Simpson Strong-Tie is a purpose-built replacement accessory kit designed to keep SDPW Deflector screw installations running smoothly and accurately. Engineered specifically for driving 6-in. Strong-Drive SDPW Deflector screws when connecting non-load-bearing walls to trusses and joists, this kit combines two T40 offset driver bits with one 3/8-in. quick-release predrill bit, giving installers a complete set of tooling for both predrilling and fastening operations in a single package.

Key Features

• T40 offset driver bits sized for 6-in. SDPW Deflector screws - matched precisely to the screw they support, so installers get a secure, slip-free drive every time without improvising with off-spec bits.
• Adjustable offset setting (3/4-in. standoff or flush drive) - gives the installer control over final screw depth, accommodating different deflection assembly requirements without switching tools.
• 3/8-in. x 5-in. quick-release predrill bit included - streamlines top-plate predrilling before Deflector screw installation, reducing split risk and keeping the job moving efficiently.
• Quick-release predrill bit compatible with most driver motors - fits the tools already on the job site, eliminating the need for specialty equipment and reducing downtime between tasks.
• Designed for use with the SDPW Deflector screw bit extension, model PW18EXT (sold separately) - integrates cleanly into a complete SDPW installation system when extended reach is required for tight or overhead framing conditions.

Why This Product

• A complete two-part solution in one kit - pairing offset driver bits with a predrill bit means a single purchase covers both the predrilling and fastening steps of Deflector screw installation, reducing the chance of arriving on-site without a critical accessory.
• Flexible depth control for real-world framing conditions - the ability to set either a 3/4-in. offset or a flush drive position makes this kit adaptable to varying deflection assembly requirements, putting control directly in the installer's hands.
• Built specifically for the Strong-Drive SDPW Deflector screw system - because these bits are engineered as dedicated replacement accessories rather than generic alternatives, they maintain the precision fitment the SDPW installation process demands.
• Compatible with standard jobsite equipment - the 3/8-in. quick-release predrill bit seats in most driver motors, so teams can integrate this kit into existing workflows without sourcing additional hardware or adapters.

Frequently Asked Questions

What screw is the PWKIT40T specifically designed to install?

The PWKIT40T T40 Offset Driver-Bit Kit is specifically designed for installing 6-in. SDPW Deflector screws from Simpson Strong-Tie.

Can the offset driver bits accommodate different driving depths?

Yes. The T40 offset driver bits can be set to provide either a 3/4-in. offset from the screw head to the wood surface, or adjusted to drive the screw flush with the wood surface, giving installers flexibility depending on the application requirements.

Will the included predrill bit work with standard driver motors?

Yes. The included 3/8-in. x 5-in. quick-release predrill bit is designed to fit most driver motors, making it a versatile choice for predrilling top plates prior to SDPW Deflector screw installation.

Is a bit extension required, and is it included in this kit?

The PWKIT40T is designed for use with the SDPW Deflector screw bit extension, model PW18EXT. However, the bit extension is sold separately and is not included in this kit.
