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.

• Large washer head with nibs provides maximum bearing area; stamped with the Simpson Strong-Tie sign and fastener length for easy identification after installation.
• 6-lobe, T40 drive provides positive engagement that makes the screw easy to drive and improves bit life.
• Low-profile head results in less interference after installation; makes stacking and sliding members easier and allows installation of hardware and finishes to be virtually flush.
• Optimal screw lengths provide maximum penetration while preventing the point from protruding out the back of the member.
• Specific thread lengths avoid jacking.
• High shear values enable wide spacing, saving time and money.
• T40 driver bit included.
