Multi-Ply Truss Screws

Multi-ply truss screws are designed for fastening together multiple layers of engineered trusses in roof and floor systems. Engineered to replace nails and through-bolts, these screws deliver superior strength, speed, and code-compliant performance. With self-tapping threads and high load capacity, they ensure trusses remain securely fastened over the life of the structure.

Why Choose Multi-Ply Truss Screws?

  • Code-Approved: Tested and approved for structural truss applications.
  • Superior Strength: High shear and withdrawal resistance ensures trusses stay firmly fastened.
  • Fast Installation: Self-tapping design eliminates pre-drilling, saving time on large-scale jobs.
  • Replaces Nails and Bolts: Provides stronger, more reliable fastening compared to traditional methods.
  • Corrosion Resistant: Available with coatings for outdoor or treated lumber applications.

When to Use Multi-Ply Truss Screws

Multi-ply truss screws are essential whenever you need to connect multiple trusses or engineered wood members together. Common applications include:

  • Securing double or triple-ply roof trusses
  • Fastening multi-ply floor trusses
  • Connecting girder trusses to distribute heavy loads
  • Engineered wood framing where bolts or nails were traditionally used

These screws speed up installation, reduce labor costs, and provide lasting performance that meets today’s building codes.

Multi-Ply Truss Screws FAQ

What makes multi-ply truss screws different from standard structural screws?

They are engineered specifically for fastening multiple layers of trusses together, offering higher load values and code approval in these applications. Standard structural screws are not always rated for truss ply fastening.

Do multi-ply truss screws replace nails or bolts?

Yes. Multi-ply screws are designed to replace traditional fastening methods, providing stronger and more consistent performance while reducing installation time.

Are multi-ply truss screws code approved?

Yes. They are tested and approved for use in structural truss assemblies. Always follow the manufacturer’s load tables and spacing requirements for compliance.

Can these screws be used outdoors?

Yes. With corrosion-resistant coatings, multi-ply truss screws can be used in exterior and treated lumber applications, such as roof trusses in open-air structures.
