The SDWS Framing screw is 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 2015 and 2018 IRC® and IBC® code requirements for several 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 6-lobe recess tightly, reducing cam-out and head stripping.

Features

Large washer head with underhead box-nibs provides increased bearing in structural applications and provides clean and easy countersinking (0.44" head dia.)

SawTooth point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications

The 6-lobe drive provides positive bit engagement resulting in easier installations and longer bit life

Quik Guard® coating provides protection in indoor and outdoor applications
