Simpson Strong-Drive SDWF FLOOR-TO-FLOOR Screw Kit SDWF2724-TUW


These screws are 24" length (5" thread length), 0.27" diameter, 5/16" hex drive. The Strong-Drive® SDWF floor-to-floor screw is designed to simplify the wind-uplift restraint connection while providing superior performance over the life of the structure. The unique design of the SDWF enables it to attach upper and lower walls together from the top, spanning the floor system and providing an easy-to-install connection within the continuous uplift load path of the structure.

The innovative TUW Take-Up Washer plays a key role in the long-term performance of the SDWF when installed between the screw and the sole plate of the upper floor. As the structure settles because of shrinkage and construction loading, the threaded portion under the head of the screw ratchets up through the tabs of the TUW, which is fastened with Simpson Strong-Tie Strong-Drive SD screw. The interlock between the tabs of the take-up washer and the threads under the head of the SDWF prevent the screw from sliding back under load, providing a simple yet reliable means of shrinkage compensation up to ¾" per story.

Each Kit includes all required installation hardware:
• 25 - Strong-Drive® SDWF Floor-to-Floor Screws
• 25 - TUW Take-Up Washers
• 100 - Strong-Drive® SD Connector Screws (#9)
• 5/16" Hex Driver Bit
• Screw Depth Guide to ensure proper SDWF engagement with TUW
• TUW take-up washer is galvanized 10ga. steel

Features:
• Faster to install than other floor-to-floor connection methods – drive the screw, install the take up washer and the connection is made from plate-to-plate
• Shrinkage compensation ensures a tight connection even after initial shrinkage and settlement occur
• Installs from inside the structure, eliminating exterior work on the upper stories and enhancing job safety
• Fastening can be done before or after exterior sheathing is applied for added flexibility
• One screw length can be used for multiple floor depths (refer to chart to select appropriate screw size), reducing the need for many screw lengths
