The thin wall bolt (TW Bolt) is a unique and innovative product. This helps to make it a convenient and flexible blind fixing solution which has been utilised by designers and architects all over the world. It also means that the various measurements given for each thin wall bolt have to be noted and adhered to when it is being used, in order to ensure successful operation.

The illustration above sets out these measurements while the menu below explains what each means.

Minimum Fixing Thickness

This term refers to the shortest distance which any individual thin wall bolt can fix. You can arrive at this figure by combining the thickness of the substances being fixed in place.

Maximum Fixing Thickness

This term refers to the largest distance which an individual bolt can fix. You can arrive at this figure by combining the thickness of the substances being fixed in place. It is possible to extend the maximum fixing thickness given by making use of a kit of extension sleeves. For more information on this option please contact us.

Tensile Strength

This term describes the force needed to cause a bolt to fail when it is handling a tensile load.

Depth Clearance

This figure refers to the smallest space needed inside a hollow section if the Blind Bolt anchor is to be able to work properly. It has to be carefully noted in order to make sure that the bolt doesn’t come into contact with the opposite wall before it’s been properly activated.
