The Simpson Strong-Drive SDWV Sole-to-Rim Screw (#10 x 4 in., Model SDWV13400) is engineered specifically to attach a sole plate to a rim board in wood framing applications. Featuring a variable thread design optimized for 2x dimensional lumber, a fast-start point with helical ridge for low-torque installation, and a large 0.400-in. rimmed flat head with nibs for increased holding power, this screw delivers reliable, consistent performance in structural framing. The E-coat electrocoating finish is intended for dry, low-corrosion service environments and is suitable for use with fire-retardant-treated (FRT) lumber in medium-corrosion, dry-service applications. This package contains 1,000 screws.

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.
