The Simpson Strong-Tie® Strong-Drive® SDW EWP-Ply Screw is built to make fastening engineered wood products (EWP) like LVL, PSL, and other multi-ply members simple, fast, and reliable. Instead of struggling with nails or flipping heavy assemblies, these screws let you pull plies tightly together from one side, saving time and effort on the job.

A large washer-style head provides extra holding power and keeps plies cinched together, while the aggressive thread design ensures a solid grip every time. The sharp SawTooth® point starts easily and drives quickly without predrilling, cutting down on installation time.

Whether you’re building beams, headers, or other structural connections with engineered wood, the SDW EWP-Ply Screw gives you a strong, code-compliant connection with less hassle.
