At Simpson Strong-Tie, we've built a heritage of steel connection innovation. Through our tireless commitment to technological advancement, research and rigorous testing, our engineers have acquired an unparalleled body of expertise, with more patents and code-listed products than anyone else in the business. Our Yield-Link moment connection is precision-made to meet the tough demands and increased loads of structural steel construction. From building owners to engineers, to contractors and fabricators, the Yield-Link's state-of-the-art design saves everyone time and money — while providing a connection that keeps structural steel buildings strong and safe.

Key Features
