• Bold thread design that provides superior holding power
• SawTooth point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
• Under-head nibs that offer greater control when seating the head
• Large washer head provides maximum bearing area (0.650-in. head dia.)
• Size identification on all SDWH screw heads
• 5/16-in. hex drive
• Driver bit included (replacement bit BITHEXR516-134)
• Length: 6 in.
• Double-barrier coating provides a level of corrosion resistance that is equivalent to hot-dip galvanization (ASTM A153, Class D) in most non-marine environments
• Quantity: 50

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.
