Introducing The Next-Generation Strong-Drive® SDHR Combo-Head Screws: Steel-to-Wood Structural Fastening Solution with Enhanced Durability and Hydrogen Embrittlement Resistance

Now with Black E-Coat Finish — Compliant with CSA O86:24 Hydrogen Embrittlement Requirements

In response to the hydrogen embrittlement requirements defined in CSA O86:24 and the increasing structural demands of modern heavy timber and mass timber construction, Simpson Strong-Tie® has developed the next-generation Strong-Drive® SDHR Combo-Head Screw with a black e-coat finish. This updated version is designed to meet the latest durability and hardness requirements while delivering the same high-capacity structural performance that engineers have come to rely on in steel-to-wood applications. The new SDHR is listed in the ICC-ES ESR-3046 Evaluation Report.

New Materials Require New Hardware — Three Fasteners Engineered Specifically for Mass Timber Construction

Simpson Strong-Tie has always been a leader in designing innovative products for various construction markets. As an R&D engineer, I enjoy the opportunities for continuous exploring, experimenting and learning that come with my role. There’s never a dull moment working in research and development! At present, I’m thrilled to be part of a team that works on developing products for construction using cross-laminated-timber (CLT) and other forms of mass timber. So I have the honor of introducing three amazing fastener products that are load rated for use in CLT, wood, glulam and structural composite lumber (SCL) products (e.g., LVL, PSL, LSL).
