Simpson Strong-Tie SDWS16300QR50 Exterior Wood Screw, #8 Thread, 3 in L, Serrated Thread, Low Profile Head, Steel

The SDWS framing screw is designed and load-rated for replacing 16d, 10d and 8d nails in framing applications. The SDWS framing screw is great to nails in holding power and pull-out resistance. It is code listed in IAPMO UES ER-192 and meets 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications. The screw has a SawTooth® point 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 six-lobe recess tightly for more secure drive control.
