Specification Considerations

Clamping Range

The clamping range of the BoxBolt connector is the combined thickness of the steel being connected and the steelwork being connected to. Each diameter of the BoxBolt connector has three overlapping lengths designed to accommodate a wide range of material thicknesses. If your clamping range exceeds those stated above, special lengths are available.

Download the catalog for a complete table of clamping ranges for each bolt.

Hole Dimensions & Positioning

It is important that the correct hole size is drilled to accommodate the body of the BoxBolt connector. Dimensions are shown in the table in the catalog. If a BoxBolt connector is being used close to the edge of a section or in close proximity to another BoxBolt connector, a minimum spacing is required to ensure that the wings are free to expand correctly.

Box Bolt Installation

Step 1 Step 2 Step 3
Align the hole in the bracket to be secured with the pre-drilled hole in the structural tube. Insert the BoxBolt connector through both pieces of steel until the underside of the shoulder is flush with the outside of the steel. Hold the hexagon shoulder of the BoxBolt connector with an open ended wrench. Use a torque wrench to tighten the core bolt. Remove the open ended wrench and check to ensure that the core bolt is tightened to the recommended torque.
