In recent years more and more projects have made use of hollow sections in structures, particularly when the projects are multi-storey in nature. The reasons driving this include the economic and structural advantages offered by hollow sections as well as the aesthetic appeal they offer. The disadvantages of hollow sections, however, include the fact that the interior of a hollow section is inaccessible in terms of tightening the bolt, and the solution to this problem involves the use of blind fixings to create a connection which is structurally sound.

Blind Bolts

As a convenient and reliable fastening solution, Blind Bolts facilitate structural steel connections when working with hollow steel sections or creating connections in places where one side is inaccessible. For many years now, blind bolts have been the fixing of choice for manufacturing, construction or repair jobs in which access is limited by the location. The ability of blind bolts to operate in circumstances such as these makes them the ultimate solution for structural connections.

The hexagonal design of the head of a blind bolt plays a crucial role in the simplicity of the installation process. This is because it means the bolt can simply be held in shape by a standard open-ended wrench. While this happens, the core bolt can be tightened using a torque wrench, and the fact that specialist equipment isn’t needed helps to explain why blind bolts are the ultimate answer for structural connections when access is difficult.

Other benefits of Blind Bolts include the tensile strength they offer. As long as you choose the right bolt for the job, you can be sure that the connection created will be high quality and long lasting. The other key benefit is the shear resistance they offer – this is a reference to the ultimate load which the join in question is able to support. The high shear resistance offered by blind bolts makes them the ideal choice for larger industrial construction projects.

Why Are They Ultimate When It Comes to Structural Connections?

Bolted connections are commonly used for structural connections because they offer the advantage of being flexible in terms of both construction and disassembly. All of this is extremely useful when the structure in question is subject to routine inspection or maintenance.

Blind Bolts fit the bill by connecting pieces of metal via the holes in the metal, and the advantages of using them include the following:


  • Structures can be put together quickly thanks to the simplicity of blind bolts, particularly if access is limited
  • The non-specialist application of blind bolts means that unskilled labourers can do the work, something which helps to reduce costs across the board
  • As soon as the blind connections are in place the structure can be used, which makes it easier to finish projects quickly
  • Blind bolts can be utilised when space is limited, something which is extremely useful in construction projects with awkward dimensions and limited room in which to work
