Ideal for structural and general-purpose fastening applications where a hex-head drive is preferred. The Strong-Drive SDWH Timber-Hex screw is ideal for the contractor and do-it-yourselfer alike. It is code listed under IAPMO-UES ER-192 and meets 2015 and 2018 IRC and IBC code requirements for several common wood framing applications.

Size identification on all SDWH screw heads
5/16-in hex drive
Driver bit included (replacement bit BITHEXR516-134)
