Why choose Arlington Coal and Lumber Company for your structural screw supplies? Structural screws, also known as structural fasteners, are heavy-duty screws engineered to replace traditional lag screws or bolts in demanding structural applications. They are designed for superior holding power and shear strength, which is crucial for securely connecting structural lumber and other materials.

Unlike standard wood screws, structural screws undergo rigorous testing and are manufactured to meet specific building codes, ensuring their reliability and safety. They often feature specialized thread patterns, hardened steel construction, and unique head designs that contribute to their exceptional strength. These screws are designed to resist pull-out, shear, and corrosion, ensuring long-term structural integrity. A key advantage is their ability to often eliminate the need for pre-drilling, saving valuable time on the job site.

Ideal projects and applications for structural screws:

• Deck Construction: Securely fasten deck joists, beams, and ledger boards to the house and support posts. Essential for outdoor decks, porches, and platforms where structural integrity and weather resistance are paramount.
  
  
• Timber Framing: Connect large timbers in post-and-beam construction. Ideal for barns, pergolas, and heavy timber structures requiring robust connections.
