Options

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 IRC^® and IBC^® code 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
SawTooth^® point 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
