The Simpson Strong-Drive SDWV Sole-to-Rim Screw, #10 x 4 in. is purpose-built to attach a sole plate to a rim board in wood framing construction. Its variable thread design is optimized for 2x dimensional lumber, while the fast-start point with helical ridge makes installation fast and low-effort. The E-coat electrocoating finish is intended for dry, low-corrosion service environments and is also suitable for use with fire-retardant-treated (FRT) lumber in medium-corrosion, dry-service applications - giving framers a reliable fastener for a wider range of job site conditions. This package contains 1,000 screws.

Key Features

• Large 0.400-in. diameter rimmed flat head with nibs - increases holding power and pulls flush against the lumber surface for a secure, consistent connection at the sole plate-to-rim board joint.
• Fast-start point with helical ridge - reduces drive torque and speeds up installation, so framers can work through a 1,000-count package without excess fatigue or bit slippage.
• Variable thread design optimized for 2x dimensional lumber - threads engage correctly in standard framing stock, reducing the risk of splitting and improving withdrawal resistance where it matters most.
• Tested in wood and engineered wood - confirms reliable performance whether the rim board is solid sawn lumber or an engineered wood product such as LVL.
• T25 6-lobe drive - provides superior bit engagement compared to standard Phillips or square drives, reducing cam-out during high-volume framing work.
• E-coat electrocoating finish - approved for dry, low-corrosion environments and rated suitable for use with FRT lumber in medium-corrosion, dry-service applications, broadening the range of compatible materials on the job site.

Why This Product

• Engineered for a specific, critical connection - the SDWV is designed from the ground up for sole plate-to-rim board attachment, meaning its geometry, thread pattern, and head profile all work together for this exact joint rather than being adapted from a general-purpose fastener.
• Compatible with fire-retardant-treated lumber - the E-coat electrocoating finish is approved for use with FRT lumber in medium-corrosion, dry-service applications, making this screw a practical choice on projects where FRT material is required by code.
• Faster, lower-effort installation at scale - the combination of the fast-start helical ridge point and T25 6-lobe drive reduces torque demand and cam-out risk, which adds up to real time savings when driving screws across an entire floor or wall framing package.
• Validated across wood and engineered wood substrates - testing in both solid wood and engineered wood members means framers can use the same screw with confidence whether the rim board is dimensional lumber or an engineered product, simplifying material planning.

Frequently Asked Questions

What is the intended application for the SDWV Sole-to-Rim screw?

The SDWV Sole-to-Rim screw is specifically designed to attach a sole plate to a rim board in wood framing applications. It has been tested in both wood and engineered wood, and its variable thread design is optimized for use with 2x dimensional lumber.

Is this screw suitable for use with fire-retardant-treated (FRT) lumber?

Yes. The E-coat electrocoating finish is intended for dry, low-corrosion service environments and is also suitable for use with fire-retardant-treated (FRT) lumber in medium-corrosion, dry-service applications. It is not recommended for high-corrosion or consistently wet environments.

What drive type and bit size are required to install these screws?

These screws require a T25 6-lobe drive bit for installation. The fast-start point with helical ridge is designed to make installation fast and easy with low torque, and the rimmed flat head with nibs helps the screw seat flush while resisting spin-out at the surface.

What are the key dimensions of this screw?

The SDWV13400 is a #10 screw measuring 4 in. in length with a shank diameter of 0.135 in., a head diameter of 0.400 in., and a thread length of 1-1/2 in. Each package contains 1,000 screws.
