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.
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
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
Installation:
* SDW screws install best with a low-speed 1/2" drill and a T-40 6-lobe bit. The matched bit included with the screws is recommended for best results.
