Expansion Anchor for Structural Steel


Product Description

BoxBolt™ is an expansion anchor for steel that can be used to make connections to structural tube sections. The BoxBolt™ is suitable for use with rectangular, square and circular sections, or other types of steelwork where access is restricted to one side only. 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 provided that will attach to most air and power tools.
