Hex Head Structural Screws

Hex head structural screws are built for the toughest wood-to-wood connections, delivering maximum torque, driving power, and holding strength. With their oversized hex head design, these screws can handle heavy-duty structural applications where strength and speed matter most. They are a proven replacement for lag bolts, making projects faster and easier without sacrificing performance.

Why Choose Hex Head Structural Screws?

  • High Torque Driving: Hex head design allows for maximum driving power with standard impact drivers or wrenches.
  • Heavy-Duty Strength: Provides shear and withdrawal resistance comparable to or greater than lag bolts.
  • Faster Installation: Drives quickly without pre-drilling in most woods, saving time on large projects.
  • Corrosion Resistance: Available with protective coatings and stainless options for outdoor and treated lumber applications.
  • Professional Choice: Widely used in framing, decking, timber construction, and engineered wood projects.

When to Use Hex Head Structural Screws

Hex head screws are ideal for applications where you need maximum power and strength, or when working with larger structural members. Common uses include:

  • Securing beams, girders, and heavy posts
  • Deck framing and ledger board installation
  • Multi-ply truss and engineered wood connections
  • Timber construction and large-scale framing

If your project demands fast installation with uncompromising strength, hex head structural screws are a go-to solution.

Hex Head Structural Screws FAQ

What makes hex head screws different from flat head structural screws?

Hex head screws allow higher torque and easier driving, especially with impact tools, making them ideal for heavy-duty work. Flat head screws sit flush with the surface for a clean finish, while hex heads protrude but maximize strength and speed.

Do hex head structural screws replace lag bolts?

Yes. They are designed as a stronger, faster alternative to lag bolts, offering code-approved performance and eliminating the need for pre-drilling in most woods.

Are hex head structural screws good for outdoor use?

Yes. With corrosion-resistant coatings and stainless steel options, they perform exceptionally well in decks, pergolas, fences, and other exterior projects.

Do I need special tools to install hex head screws?

No. They can be driven with common impact drivers or wrenches, and their large head design makes driving easier compared to standard screws.
