Cross-Laminated Timber (CLT) Screws

Cross-laminated timber screws are engineered for use in mass timber construction, providing the strength and length needed to fasten CLT panels, glulam beams, and other engineered wood members. These long structural screws eliminate the need for traditional through-bolts, making installation faster, cleaner, and fully code-compliant for today’s modern building projects.

Why Choose CLT Screws?

  • Extra Length: Available in long sizes designed specifically to penetrate thick CLT panels and engineered wood members.
  • High Load Capacity: Provides superior shear and withdrawal resistance compared to nails or bolts.
  • Faster Installation: Self-tapping design eliminates pre-drilling in most applications, saving time on the jobsite.
  • Code-Compliant: Tested and approved for structural CLT and glulam connections.
  • Corrosion Resistant: Protective coatings make them suitable for both interior and exterior mass timber applications.

When to Use CLT Screws

CLT screws are designed for modern engineered wood construction projects that demand both strength and efficiency. Common applications include:

  • Fastening CLT panels in mass timber walls, floors, and roofs
  • Securing glulam beams and posts
  • Attaching structural timber members without through-bolts
  • Large-scale residential, commercial, and institutional timber projects

By using CLT screws, builders reduce labor time, avoid the mess of through-bolting, and achieve reliable, code-compliant connections in large timber assemblies.

Cross-Laminated Timber Screws FAQ

What makes CLT screws different from regular structural screws?

CLT screws are engineered in extra-long lengths to fasten thick CLT panels and engineered wood members. Standard structural screws are often too short or not rated for these applications.

Do CLT screws replace through-bolts?

Yes. CLT screws are designed to replace traditional bolting methods, offering easier installation, cleaner finishes, and equal or greater structural performance.

Are CLT screws code approved?

Yes. Many CLT screws are ICC-ES approved for use in mass timber applications, ensuring compliance with building codes and engineering specifications.

Can CLT screws be used outdoors?

Yes. Many are available with corrosion-resistant coatings or stainless steel options, making them suitable for exterior timber construction.
