M20 Size 1 BoxBolt (Fixing Range 8-42mm)

M20 Boxbolt™ is used for steel to steel connections clamping thickness between 8-42mm thickness.

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.
