Applications For Blind Bolts

One of the most versatile fasteners available on the market today is the blind bolt. These bolts are so adaptable that knowledgeable users who understand how they work are creating new ways to use them. As a result, manufacturers are busy making additional sizes to expand their use even more.

There was a time when fixing into a box section or girder cavity was a major undertaking. However, the blind bolt has made this application a snap to achieve and actually saves money in the process.

Applications That The Blind Bolt Tackles Easily

There are a number of applications the Blind Bolt can tackle. They include:

Hollow Section

Hollow sections are lightweight and mechanically efficient form of fixing that is often used due to their artistic attractiveness. Hollow sections feature a torsional stiffness that is ideal for supporting unconventional loads including cladding and infill panels. They require the twist be controlled.

Since hollow sections don’t suffer from lateral torsional buckling, they are ideal for serving as struts in bracing systems. The closed profile makes them suitable to serve as unrestrained members.

When compressed, square and circular hollow sections have the same resistance in their right angles that are statistically independent, which also makes them ideal as struts in bracing systems.

Their closed profile makes them also ideal where the gathering of debris on the flanges on open profiles needs to be prevented.

Masonry Support Systems

Blind Bolts are ideal fasteners for connecting masonry support systems to hollow section.

Masonry support systems are commonly used to reinforce the external leaf of masonry on wall clad buildings with a bracket angle support.

Also referred to as Brickwork Support Systems, they offer a horizontal ledge that can handle the weight of the masonry wall panels above.

Various masonry restraints fix back the steel angles to the structural frame depending on whether it is a steel frame or concrete frame.

Blind Bolts or Heavy Duty (HD) Blind Bolts are the most suitable fixing option because they are fast and easy to install.

There are four main types of masonry systems. They include the continuous angle, welded steel bracket angle, individual bracket angle support and off the shelf system.  Masonry support systems are manufactured using grade 304 stainless steel.

Cladding & Facades

Blind bolts are also ideal for fixing Cladding and Facades.

The term “cladding” involves components that are attached to primary structures of buildings to create non-structural, external surfaces. Although cladding is generally attached to a building, it does not commonly cause its stability.

Still, cladding does offer a structural character by transferring the wind load, impact loads, snow loads, or its own self-weight back to the structural frame.

Wind causes positive and negative pressure on the surface of buildings so cladding must have sufficient strength and stiffness to resist the load.


Blind Bolts are also terrific for a number of marine fixing applications. When making connections in a marine environment it is common that one uses stainless-steel fixings. All Blind Bolt products are made from 316-grade (A4) stainless steel.

Some examples of projects using Blind Bolts in marine applications include retaining wall strengthening and pontoon installation.

Learning about applications that are ideal for the use of Blind Bolts shows that one size does not fit all. You need to select the proper fastener for the job.
