Simpson Strong-Drive SDW EWP-PLY Screw

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 predrilling and is available in optimized lengths for fastening 1 3/4″ 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 IRCand IBCcode requirements for most common wood framing applications.

Key Features

• 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 (replacement driver bit BIT40T-134-R2)
• 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 avoids jacking
• High shear values enable wide spacing, saving time and money
• Bold thread design provides superior holding power and cinches fastened members together for consistent installation
• SawToothpoint ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
• Retail and mini-bulk packs include one 6-lobe, T40 driver bit; bulk packs include two driver bits

Applications

• Multi-ply wood members, engineered lumber products and solid sawn lumber
