Blind Bolts; The Ultimate Solution for Structural Connections

Blind Bolt Fixings

More and more construction projects – particularly those which are multistory in nature – use hollow sections within the structure. The reasons driving this trend include the aesthetics of the finished building as well as the structural and economic benefits offered by hollow sections. The problem which hollow sections present is that it can be impossible to access the interior of a section in order to tighten the bolt. This rules out standard bolts, and means that blind bolt fixings have to be used to ensure structurally sound connections.

Blind Bolts

Blind bolts offer a combination of convenience and reliability for structural steel connections. They can be equally useful whether connecting hollow steel sections or creating a sound connection where one side of the steel can’t be reached. For many years now, blind bolts have been the fixing of choice for those occasions when access is limited, whether that means construction, manufacturing or repairs. This helps to explain why blind bolts are the ultimate solution for modern structural connections.

The installation process for a blind bolt is aided by the hexagonal design of the head. This shape enables the bolt to be held in place with the use of an open-ended wrench. At the same time, the core bolt can be strengthened using a standard torque wrench. This ease of use helps to explain why blind bolts are the best solution for a huge range of structural connections.

The many benefits offered by Blind Bolts include the fact that they provide high tensile strength – as long as you select the correct blind bolt for the circumstances, you can look forward to a durable, high-quality connection. In addition to this is the fact that blind bolts offer fantastic shear resistance, which is a measure of the ultimate load which can be supported. The high shear resistance offered by the blind fixings manufactured by BlindBolts makes them the ideal solution for large scale industrial construction projects.

Why Are They Ultimate When It Comes to Structural Connections?

Bolted connections are amongst the most common structural connections. They offer the advantage of flexibility in terms of how they can be constructed and, in addition, disassembled. This can be extremely useful on those occasions when routine maintenance or an inspection of the structure is required.

Blind Bolts offer a simple solution – they connect pieces of metal by simply being inserted through holes in the metal, and the advantages of using them include:


  • Structures can be erected much more quickly thanks to the simplicity of using blind bolts when access is restricted
  • The simplicity of application means that untrained laborers can perform the task, and this helps to keep costs down
  • The fact that the structure in question can be used immediately after the application of blind bolts helps to save time when completing projects
  • The space needed to fit a blind bolt isn’t huge, which can be helpful in construction projects when space is often at a premium
