Simpson Strong-Tie SDWF2720-TUW Strong-Drive® SDWF FLOOR-TO-FLOOR Screw — 0.270 in. x 20 in. 5/16 Hex, E-coat® (25-Qty)

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 Take-Up Washer (TUW) plays a key role in the long-term performance of the SDWF when installed between the screw head and the sole plate of the upper floor.
