DESCRIPTION

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, ledgers and general interior applications. These 0.195 and 0.22 in Dia structural fasteners require less torque to install than comparable fasteners and the large diameter washer head pulls members down easily, eliminating the need to use extra washers. It is code listed under IAPM-UES ER-192 and meets 2015 and 2018 IRC® and IBC® code requirements for several common wood framing applications. SawTooth® point ensures fast starts, reduces installation torque and eliminates the need for pre-drilling in most applications Serrated thread reduces splitting and damage Low-profile, large diameter washer head with nibs provides maximum bearing area and makes countersinking easy Six-lobe, T40 drive provides positive engagement that makes the screw easy-to-drive and improves bit life (replacement driver bit BIT40T-134) Size identification on all Simpson Strong-Tie® screws
