BoxBolt™ is suitable for use with rectangular, square and circular steelwork sections, or other types of metalwork where access is restricted to one side only.
BoxBolt is a blind bolt connector that can be tightened down from one side. The hexagonal sleeve 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.
Consult the technical data listed below for minimum and maximum clamping ranges.
To reduce installation time, a one piece accessory called the BoxSok™ can be used to attach to most air and power tools.

The Safe Working Loads are based on assemblies tested in typical conditions.
|Model||Dimensional Information||Load Information|
The loads stated above are based on the LRFD (Load & Resistance Factor Design) method recommended by the AISC for bolted steel connections. This uses a factor of 0.75 of the ultimate load and therefore equates to a 1.33 to 1 factor of safety that we have applied to our published loads above. The overall strength of the connection is governed by the strength of material our BoxBolt is connecting into; therefore, this should be checked for structural capacity by a structural engineer.
