Box Bolt - Expansion Bolt for Blind Connections to Structural Steel

BoxBolt™ is an expansion anchor that can be used to make connections to structural sections when access is restricted to one side.

The BoxBolt™ is suitable for use with rectangular, square and circular sections, or other types of metalwork where access is restricted to one side only. Ideal for use on hollow steel work.

The shoulder of the 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.
