  • Provides flexibility to allow for site tolerances

BoxBolt Steel Connectors

BOXBOLT is CE certified in compliance with Regulation 305/2011/EU of the European Parliament and the Council of 9 March 2011 (the Construction Products Regulation or CPR). BOXBOLT is also approved for use by Lloyds Register (LR) type approval.

BOXBOLT complies with the DIN 18800 and Eurocode 3 design methods for bolted steel connections. When using these methods, a design guide and calculator are available; pleaseĀ ask our technical team for more information.


Why use BOXBOLT Blind Fixing?


  • No Access to both sides of the connection is required.

  • No need for close tolerance holes or tapping.

  • No special tools are required – two spanners only.

  • Installation by semi-skilled labour.

  • Only the BOXBOLT head is visible when installed.

  • Approved for use by Lloyds Register Type.

  • Exceptional Shear loading performance.

  • AISC and Eurocode 3 Method for designing connections.


  • The connection can be made blind for connections into hollow sections or where access is restricted.
  • New holes can be drilled quickly on-site if required.
  • No hire/purchase of specialist equipment or the need to move around heavy equipment.
  • Connections can be made much quicker without special skills or equipment.
  • Aesthetic connection.
  • Third-party accreditation for use in tensile and shear applications.
  • Less BOXBOLT fixings can be used to make shear connections.
  • Provides a simple to follow design procedure that is the same as standard bolted connections.


  • No through bolting or strapping is required reducing fabrication work.
  • Flexibility and reduced on-site installation time.
  • Reduction in installation cost and administration.
  • Reduction in labour and hire costs.
  • Flexibility in Architectural design.
  • Confidence that the connection will perform as stated without site proof testing required.
  • Flexibility in design and possible cost reductions.
  • Designers easily recognise the method and can save costs on competitive methods.
