The Strong-Drive SDW EWP-Ply screw is a high-strength structural wood screw specifically designed for fastening multi-ply members made up of engineered-wood products. The SDW EWP-Ply installs easily with no pre-drilling and is available in optimized lengths for fastening 1-3/4 in engineered lumber, such as structural composite lumber (SCL). The large, flush head eases the handling of assembled components and simplifies the installation of finishes or structural connectors. 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.
