Strong-Tie SDW EWP-Ply screws are specifically designed for fastening multi-ply wood members, such as engineered-wood products and solid-sawn lumber. The SDW EWP-Ply screw installs easily with no pre-drilling and is available in optimized lengths for fastening 1-3/4" engineered lumber, such as laminated veneer lumber, LVL, or structural composite lumber, SCL. Low-profile head results in less interference after installation, makes stacking and sliding easier and allows finishes to be virtually flush.
