Description
Our #14 x 2-7/8" Flat Head Torx Structural Wood Lag Screws are heavy-duty, construction-grade fasteners engineered for demanding exterior wood projects. Crafted from premium low-carbon steel with HRC 44.5-52 case hardness, these screws deliver exceptional strength and durability, making them ideal for decking, timber framing, landscape structures, and other heavy-duty outdoor applications.
Designed with a high-efficiency quick-drive thread profile, the screws bite aggressively into wood, driving straight with remarkable ease to reduce installation time and labor effort. The dual knurl shoulder design distributes clamping force evenly, creating a vibration-proof, rattle-free connection perfect for high-stress structures like decks, furniture, and framing. The radial serration anti-loosening teeth eliminate the need for separate washers, ensuring a permanently tight, secure connection even under constant stress and movement.
Featuring a standard flat head with T30 Torx (star) drive, these screws combine industry-preferred torque transfer with a flush, seamless finish, eliminating protruding screw heads for a clean, professional appearance. The Torx drive outperforms traditional Phillips and square drives, drastically reducing bit slippage and head stripping for reliable, efficient installation. The upgraded anti-cracking design prevents wood splitting during installation, outperforming standard screws and protecting hardwood and softwood materials.
