Testing Data Explained
TW Bolt Testing Terms Explained
Utilising the unique and innovative TW 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.
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.
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. Extension sleeves are available which can be used to significantly extend the maximum fixing thickness. For more information on extension sleeves please contact us.
This is a measure of the pull-out force needed for the bolt to fail when a tensile load is being applied.
This figure is the minimum space needed within the cavity wall for the legs on the TW Bolt 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 being correctly installed.
