SDWS Timber Screw
The Simpson Strong-Tie® Strong-Drive® line of structural fasteners now includes the SDWS Framing screw, designed and load-rated for replacing 16d, 10d and 8d nails in framing applications. The SDWS Framing screw is 0.160″ in diameter and superior to nails in holding power and pull-out resistance. It is code listed under IAPMO UES ER-192 and meets 2009 and 2012 IRC® and IBC ®code requirements for several common wood framing applications.
The screw has a SawTooth™ Type-17 tip with serrated threads that makes for fast installations with reduced torque without predrilling, and its specially designed head countersinks easily to provide a clean, flush finish. The T25 bit holds the 6-lobe recess tightly, reducing cam-out and head stripping.
