The Strong-Drive SDWS Timber screw is a structural wood screw available in a variety of lengths and is designed for cross-laminated timber construction, mass timber construction and general interior applications. These 0.195 in. and 0.220 in. diameter structural fasteners require less torque to install than comparable fasteners. The large diameter washer head pulls members down easily, eliminating the need to use extra washers. It is code listed under IAPMO-UES ER-192 and meets IRC and IBC code requirements for several common wood framing applications.
