BoxBolt Expansion Anchor- Saving Time, Saving Money

‘They often say that time is money. The idea of BoxBolt is to drastically cut down on the time of labour, thus being a huge money saver in the process’.

Expansion Anchor

Working with structural steel every day can throw up all kinds of obstacles and dilemmas which can slow down work and provide delays.

Cutting out steel and welding can be time consuming, and a lot of the time, this extra work is completely unnecessary. BoxBolt is an expansion anchor which is particulary effective for hollow section steelwork where access is restricted to one side.

Tested and Approved

BOXBOLT is approved for use by Lloyds Register (LR) type approval and the Deutsches Institut für Bautechnik (DIBt). Our DIBt approval complies with Eurocode 3 / DIN 18800 providing the designer and user with total confidence and peace of mind.

It is fully tested, and is suitable for connecting to square, rectangular and circular hollow sections.

So how does it work?

BoxBolt expansion anchor works in a very simple way. As its hexagonal shoulder is held in place with a wrench, a torque wrench can then be used to tighten the core bolt. The threaded wedge is then withdrawn inside the body. As this happens, the fins expand and tighten inside the steel beam, ensuring a secure connection.




Alternatives

  • Drilling and tapping
  • Welding
  • Strapping
  • Thru Bolting
  • Access Holes

All of these methods will get the job done, but are more time consuming, drastically so in some cases. The BoxBolt blind fixing bolt needs to be secured from one side only, and will ensure a clean, neat finish combined with the steel being held securely in place.

There won’t always be an option to box around steel beams with timber/ply wood. In this case, aside from the convenience of Box Bolt and saving money, it provides a much cleaner and neater finish from an aesthetic point of view.

Benefits of BoxBolt Expansion Anchor

So aside from the speed of installation, what are the benefits of BoxBolt?

  • Reduction in installation and labour time and cost
  • Flexibility in Architectural design
  • There is no through bolting or strapping required, which will reduce fabrication work
  • No specialized or skilled labour required
  • No need for specialized tools, just two spanners required
