Blind Bolts; The Ultimate Wall Cladding Fixing Solution

Blind Bolts

The quickest and simplest way to completely alter the outward appearance of a tired and ageing building is to apply cladding. While remaining separate from the building itself, it will create a strong, durable and aesthetically pleasing solution. As well as improving the appearance of the building, it will also offer a greater level of insulation. Without having to rebuild the structure entirely, cladding offers a means of completely updating it.

When metal cladding is applied to the exterior of a building it has to function effectively as well as looking appealing. Effective functioning in this case means being able to support both the weight of the cladding itself and the additional impact of factors such as snow and other weather conditions. In addition to this, the pressure of wind on the outside of the building can also cause serious damage if the cladding has not been attached as securely as it could be.

The demands placed on cladding help to explain why blind bolts have become such a popular choice throughout the construction industry. As well as offering tensile strength and durability, they are flexible and versatile enough to be utilised across all types of modern projects.

Reasons Blind Bolts Are So Useful

If you’re looking for a finish which is more secure than rivets or welding, and can be used across a wide range of applications within the construction industry, then you’re looking for blind bolts. They are particularly suited to attaching steel to steel, which helps to make them the ideal choice for large infrastructure construction projects such as bridges. In addition to this, however, they are increasingly used thanks to the architectural trend for large and heavy expanses of glass in domestic and commercial buildings. Part of the appeal lies in the simplicity of application – just insert the blind bolt into a pre-drilled hole without having to access the other side of the join. Once it’s fixed in place you’ll have a joint which is extremely strong and long lasting. When it comes to fixing cladding to the exterior of a building, you won’t find a better solution.

The Advantages of Blind Bolts

Blind bolts have emerged as the leading choice for the majority of construction projects and this has been driven by the following advantages:


  • Tensile strength – You’ll be guaranteed a strong and durable connection provided you select the right blind bolt for the job in hand. The key measurement is the ‘grip’, which covers the total thickness of the two materials being joined together. If this is measured properly, the resulting joint will offer great longevity.
  • Shear resistance – The shear resistance of the blind bolt refers to the maximum load it is capable of supporting. The high shear resistance of blind bolts makes them the ideal choice for larger scale projects or those involving industrial construction.
  • Ease of application - Blind bolts were named after the fact that they can be utilised in situation in which the reverse side of the joint being created can’t be accessed. This ease of application makes them invaluable across a wide range of construction projects.
  • Corrosion resistance – Blind bolts are manufactured in a wide range of materials for the broadest possible application. Those manufactured from A4 stainless steel, for example, are resistant to corrosion when used in environments which feature seawater.
