BoxBolt is the Simplest and Fastest way to Connect
to Hollow Structural Sections

Simplify Steel Connections


Easily install from one side of your connection, eliminating the need for rear access. BoxBolt products are structural anchor bolts which rid the need of onsite drilling or welding through bolting

Safe Solution


Unlike a welded solution, BoxBolt allows you to know exactly what your safe working loads are with a 5:1 safety factor. BoxBolts comply with International Building Codes.

Save Time on Installation


No need for a hot weld permit and only requires you to drill one hole in your structure.

How Can BoxBolts
Help Your Project

A Faster Way with BoxSok

To tighten down a BoxBolt, an installer must typically use 2 wrenches to install one bolt - one to hold the outer sleeve stationary, and one to turn the inner bolt.

The BoxSok adds simplicity to the installation process. Attached to a regular socket wrench (air powered makes this a snap), it takes the place of both wrenches. The BoxSok has an outer piece that will hold the sleeve of the BoxBolt stationary, while an inner piece turns the bolt. This makes what would have been a 4 minute job (per bolt) into a 30 second job.

Box Bolt Installation Examples

Application Examples

BoxBolt connectors are used here to secure a bracket to structural tube.
Structural tube to structural tube sections being connected with an angle bracket.
Structural tube with drilled end plate being connected to vertical structural tube.
The core bolt down the center of the BoxBolt connector can be replaced with threaded rod, eyebolts or other threaded items.
By inserting one structural tube inside another, a sleeve connection can be easily made using the BoxBolt connector.
The BoxBolt connector is suitable for most profiles of structural tube, including circular sections.
The BoxBolt connector can be used with other BeamClamp products to connect structural tube sections to existing steel without the need for site drilling and welding.
The BoxBolt connector can be used to secure glazing panel brackets to building structures with access only required from one side.
The BoxBolt connector can be used to connect any bracket, such as the mounting plate of handrails to structures, with access only required from one side.

The First Blind Fastener To Achieve
ICC Testing And Approval


The ESR-3217 approval document has been published on the ICC website. For a complete list of testing criteria and load ratings, download the BoxBolt catalog.

Some 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 Box Bolt 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.
