3-3/8" SDW Structural Wood Screw

Structural Wood Screws are designed with a shorter thread length to fasten multi-ply members such as trusses, engineered lumber products and solid-sawn lumber.

Large washer head provides maximum bearing area and deep 6-lobe recess reduces cam-out.

Requires type T-40 bit.

Optimal screw lengths provide maximum penetration while preventing the point from protruding out the back member.
