How It Works

How It Works

The Original BoxBolt is a fully tested and approved blind structural bolt solution for connecting to hollow section steel, or structural connections which access is restricted to only one side. The BoxBolt is suitable for rectangular, square, and circular hollow sections. The structural steel anchor bolt features a hexagon head designed to be installed with a standard wrench. Our unique BoxSok installation tool is also available for faster installation.
