BoxBolt is suitable for use with rectangular, square and circular sections, or other types of steelwork where access is restricted to one side only.
BoxBolt is hexagonal. This allows it to be held in position with an open ended wrench while a torque wrench is used to tighten the core bolt. As the core bolt is tightened the threaded wedge is drawn up inside the body, the fins expand, and a secure connection is made. To reduce installation time, a one piece accessory called the BoxSok can be used to attach to most air and power tools.
