Fastener Selection for Timber-to-Steel Connections: Sizing and Corrosion Checks

An architectural engineering guide to mass timber construction, self-tapping structural wood screws, and high-capacity steel-to-timber connectors.

Fastener Selection for Timber-to-Steel Connections: Sizing and Corrosion Checks

Timber construction fasteners

Cross-laminated timber (CLT) and mass timber construction are booming worldwide. However, wood is a living material that expands and contracts with humidity, putting unique shear stresses on fasteners.

Engineering for Wood Dynamics

Our specialized structural timber screws and heavy dowel fasteners are engineered with high bending yield strength to prevent shearing when wood shifts seasonally.


FAQ: Timber Screws

  • Q: Why can't standard drywall screws be used in timber framing?
    A: Drywall screws are brittle and lack the shear strength required for structural wood loading.
