Blind Bolt Fixing Terms Explained

Utilising the unique and innovative Blind Bolt system effectively means being fully aware of the way in which the dimensions of the bolt are measured and classified.

These dimensions then play a vital role in meeting the criteria for successful application.

The details of these measurements are set out below and the menu above offers pictorial representations.

Minimum Fixing Thickness

This figure is the minimum distance which the bolt in question is able to fix. It is calculated using the combined thickness of the materials being clamped.

Maximum Fixing Thickness

This figure is the maximum distance which the bolt in question is able to fix. It is calculated using the combined thickness of the material being fixed.

Anchor Clearance

This figure is the minimum distance within which the Blind Bolt can be deployed effectively. It has to be noted carefully when using the bolts to fix into Steel Hollow Sections, as this will make sure that the anchor doesn’t catch on the section wall.

Depth Clearance

This figure is the minimum space needed within the cavity wall if the anchor on The Blind Bolt is to deploy effectively. It has to be noted carefully when using the bolts to fix into Steel Hollow Sections, as this will make sure the bolt doesn’t reach the opposite section wall prior to deployment of the anchor.

The Hole Centres

This figure is the minimum distance between holes when using the bolts in multiple numbers.
