Product Overview
SDWS22512 Strong Drive Timber Screw
The Strong-Drive SDWS Timber (Interior Grade) screw – formerly, the SDWS Log screw – is a structural wood screw available in a variety of lengths and is designed for cross-laminated timber assemblies, mass timber construction, log-home construction, ledgers and general interior applications. These 0.195"- and 0.220"-diameter structural fasteners require less torque to install than comparable fasteners, and the large-diameter washer head pulls members down easily, eliminating the need to use extra washers.
Key Features
SawTooth point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
Serrated thread reduces splitting and damage
Large, low-profile .075"-diameter washer head with nibs provides maximum bearing area and makes countersinking easy
6-lobe, T40 drive provides positive engagement that makes the screw easy to drive and improves bit life (replacement driver bit: BIT40T-134)
Size identification on all Simpson Strong-Tie screws
US Patent: 9,523,383
Applications
Surface splines, lap joints, timber framing, ledgers, log-home construction and general interior applications
Testing in a variety of mass timber applications is underway
Product Includes - Replacement driver bit: BIT40T-134
Warning
Industry studies show that hardened fasteners can experience performance problems in wet and corrosive environments. Accordingly, use this product in dry, interior and noncorrosive environments only.
