Strong-Drive® SDW Interior Structural Wood Screw

 

The Strong-Drive® SDW screw is a 0.22" diameter, high-strength structural wood screw specifically designed for fastening multi-ply wood members such as plated trusses, engineered-lumber products and solid-sawn lumber. The SDW installs easily with no pre-drilling and is available in optimized lengths for fastening 2, 3 and 4-ply trusses or 1 3/4" engineered lumber such as structural composite lumber (SCL). The SDW enables single-side fastening, while still allowing concurrent loading on both sides of the assembly to the full allowable head or tip-side load of the fastener. fastener.

Low-Profile Head

 

Features:
  • A high-strength structural wood screw designed with a shorter thread length to fasten multi-ply members such as plated trusses, engineered-lumber products and solid-sawn lumber.
  • Large washer head provides maximum bearing area; stamped with the Simpson Strong-Tie "≠" sign and fastener length for easy identification after installation.
  • Deep 6-lobe recess reduces cam-out, making driving easier.
  • Low-profile head results in less interference after installation; makes stacking and sliding members easier and allows installation of hardware and finishes to be virtually flush.
  • Optimal screw lengths provide maximum penetration while preventing the point from protruding out the back of the member.
  • Ability to penetrate multi-ply trusses from only one side eliminates the need for flip trusses.
  • Higher shear values than competitive products enable wider spacing saving time and money.
  • Bold thread design provides superior holding power and cinches fastened members together for consistent installation.
  • Patented 4CUT™ point ensures fast starts, reduced installation torque and eliminates the need for pre-drilling in most applications.
  • Under-head nibs provide greater control when seating the head.
  • E-coat™ coating is suitable for interior applications only.
