Simpson Strong-Tie SDWS22800-R50 8" x .220" Log Home Structural Screw E-Coat - 1 each

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. 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.

Key Features

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

  • 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
  • Surface splines, lap joints, timber framing, ledgers, log-home construction and general interior applications
  • Testing in a variety of mass timber applications is underway
