Strong-Drive^® SDWS^™ TIMBER Screw (Interior Grade)

Product Details

The Strong-Drive SDWS Timber (Interior Grade) screw – formerly, the SDWS Log screw – is a structural wood screw available in a variety of lengths and is designed for cross-laminated timber assemblies, mass timber construction, log home construction, and general interior applications. These 0.195"- and 0.220"-diameter structural fasteners install faster and easier than comparable lag screws, and the large-diameter washer head pulls members down easily, eliminating the need to use extra washers. It is code listed in IAPMO-UES ER-192 and meets 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications.
