ICC Evaluation Service (ICC-ES) has issued the first Canadian listing report (ELC) to CSA O86 for Wood Screws to structural building product supplier Simpson Strong-Tie. The CSA O86 standard, referenced in the National Building Code of Canada (NBCC), provides criteria for the structural design and evaluation of wood structures or structural elements.

The Simpson Strong-Tie Strong-Drive® SDCF, SDCP and SDHR screws are manufactured using a standard cold-forming process and are heat-treated. The screws are alternative dowel-type self-drilling fasteners, and have met the testing requirements for fastener shear, tension, bending yield strength, withdrawal resistance, and lateral resistance, among others.

“Simpson Strong-Tie Strong-Drive screws are fasteners for cross-laminated timber and mass timber construction that do not require pre-drilling,” said Simpson Strong-Tie Sr. Engineering Manager – Fastening, Robert Leichti, PhD. “Obtaining a Canadian listing report reflects our commitment to third-party product review, better ensuring code compliance and product performance. We appreciate the robust and timely review that ICC-ES provides that is facilitated by their publicly developed and publicly available Acceptance Criteria.”

ICC-ES is one of only a few evaluation entities in the U.S. accredited by the Standards Council of Canada to evaluate building products to the NBCC. As a result, ICC-ES Canadian listing reports are accepted in all Canadian provinces and territories.
