Structural Screw Catalog

MTC Solutions’ Structural Screw Catalog is our most comprehensive guide for structural self-tapping screws. It provides designers and installers with a complete set of practical & technical information organized in an easy-to-read chapter structure. It includes all design formulas needed to determine your connections’ capacities, specific installation guidelines with geometry requirements in a wide variety of situations, tools recommendations, service conditions, and all ASSY fastener references to specify in your design.

The structural screw catalog is a go-to tool to design connections and properly install fasteners in your cutting-edge and code compliant mass timber projects.
