Blind Bolt Testing Data Explained

Testing data explained blind bolt

The versatility of the Blind Bolt design means that there are numerous fixing combinations possible in any given scenario. This leads to variation in the measured strength of each Blind Bolt thanks to the testing data. The tensile strength of the Blind Bolt remains the same no matter how it is used, but the shear strength is dictated by the thickness of the actual substance being clamped.

An overview of these variations is set out below and more detail can be found in our technical data sheets. These sheets can be accessed via the menu at the top of the page.

What is Tensile Strength

The tensile strength of a Blind Bolt is the pull-out force needed for the bolt to fail when a tensile load is acting upon it.

What is Shear Strength Over Slot

This is a measure of the force needed for the bolt to fail when the shear plane falls over the slotted portion of the Blind Bolt. The shear plane is the area produced by the two materials which the bolt is clamping together. If the Blind Bolt has been installed using the correct vertical alignment, the slotted portion will be found close to the anchor.

what is Shear Strength Over Thread

The shear strength over thread is the force needed for the bolt to fail if the shear plane produced by the materials being clamped together falls over the threaded section of the bolt.
