SDW Structural Wood Screws

The SDW Structural Wood Screw range is an elite, high-torque selection of heavy-duty timber fasteners engineered for high-capacity structural wood-to-wood connections. Specifically developed to streamline the installation of multi-ply engineered wood products, such as laminated veneer lumber (LVL), parallel strand lumber (PSL), and solid timber beams, these screws provide an unyielding mechanical connection interface without the need for pre-drilling. Ideal for heavy framing layouts, joist splicing, roof carpentry, and multi-ply beam tracking, this professional collection serves as a fast, code-compliant alternative to traditional through-bolts and coach screws.

High-Torque Drive Geometry

Features a deep-recess drive interface that maximizes torque transfer while preventing cam-outs, driving effortlessly through dense engineered timber grain fields to dramatically reduce on-site installer fatigue and tracking time.

Low-Profile Washer Head

Engineered with a broad, flat clamping head that delivers exceptional pull-through resistance, countersinking flush against the wood interface to allow secondary materials or external finishes to slide smoothly over the joint.
