Simpson Strong-Drive SDPW Deflector Screw, 0.195 in. x 6 in., T40 6-Lobe Drive is a premium structural fastening solution engineered specifically for connecting non-load-bearing walls to trusses and joists. With tested lateral-load ratings that meet building code requirements, this washer-head wood-to-wood screw delivers the strength, installation speed, and safety that framing professionals demand. The E-coat electrocoating finish provides a durable gray surface that resists corrosion, making this deflection screw a reliable choice for interior partition wall applications where long-term performance matters. The built-in polymer sleeve allows the screw to slide during natural deflection events - keeping connections tight and squeak-free over the life of the structure.

Key Features

• E-coat Electrocoating Finish - provides a consistent, durable protective barrier over the entire fastener surface, extending service life and maintaining structural integrity over time
• T40 6-Lobe Drive - delivers high torque transfer with reduced cam-out risk, allowing faster, more controlled installation even in overhead or awkward framing positions
• Washer Head, 0.650 in. Diameter - spreads clamping force over a larger bearing surface, improving load distribution against the wall framing member
• SawTooth Point - self-starting tip bites into wood quickly, reducing the effort and time required to initiate the fastener without pre-drilling the shank
• Serrated Threads with 3 in. Thread Length - aggressive thread engagement locks into the supporting truss or joist for tested lateral-load performance that meets building code standards
• Polymer Sleeve Design - allows natural sliding during differential deflection between the wall and supporting member, actively preventing squeaks and structural stress buildup
• Includes Offset Driver Bit and Predrill Bit - maximizes installation speed and safety in tight framing bays while minimizing installed cost by eliminating the need for separate tooling
• 0.195 in. Shank Diameter, 6 in. Length - sized for deep, secure penetration into truss and rafter plates, ensuring reliable structural connection through full wall assembly thickness

Why This Product

• Built for deflection applications - the polymer sleeve is specifically engineered to allow sliding movement during the natural differential deflection between non-load-bearing walls and trusses or joists, a problem that standard screws cannot address without causing squeaks or fastener stress
• Code-compliant lateral-load ratings - tested lateral-load values meet building code requirements, giving contractors and inspectors confidence in the structural performance of every partition wall connection
• Everything needed is in the box - the included T40 offset driver bit and 3/8 in. quick release predrill bit let installers get straight to work without hunting for compatible tooling, reducing downtime on the job site
• Value-engineered for production framing - the combination of SawTooth point, serrated threads, and offset driver bit is designed to minimize installed cost by increasing installation speed while maintaining the structural ratings required for non-load-bearing wall-to-truss connections

Frequently Asked Questions

What makes the SDPW Deflector Screw different from a standard structural wood screw?

The SDPW features a polymer sleeve that allows the screw to slide during differential deflection between a non-load-bearing wall and the truss or joist above it. This sliding action prevents squeaks and reduces stress on the fastener - something a standard structural screw without a polymer sleeve cannot do in deflection applications.

Does this screw require pre-drilling before installation?

The SawTooth point is designed to self-start into wood framing. However, the included 3/8 in. quick release predrill bit is provided alongside the T40 offset driver bit to support proper installation technique and maximize installation speed and safety as recommended for this fastener.

What drive bit does this screw require?

This screw uses a T40 6-Lobe drive. A T40 offset driver bit is included with the screws to allow fast, safe installation in tight framing bays such as between wall plates and trusses or rafters where a straight driver cannot easily reach.

Is this screw rated to meet building code requirements for structural connections?

Yes. The Strong-Drive SDPW Deflector Screw has tested lateral-load ratings that meet building code requirements for connecting non-load-bearing partition walls to trusses and joists. The value-engineered design delivers the strength needed for code-compliant framing connections.
