Available in a wide variety of shapes and sizes, our fastener line provides viable mass timber connection solutions for all structural timber systems.

Partially Threaded

Fully Threaded

Screws are ICC-ESR-approved fasteners are designed to hold wood members firmly in place. Fully Threaded ASSY screws are often utilized to take advantage of their high withdrawal capacities through axial loading using installation angles other than 90°. They are also specially suited for reinforcement applications.
