Blind Bolt Testing Data Explained

Blind Bolt testing Data

Blind Bolts are incredibly versatile and can be used in a wide number of fixing combinations. This variety means that the measured strength of the Blind Bolt in question can also vary. This where the testing data comes in.

Whilst the tensile strength of the Blind Bolt is constant no matter how it is used, the shear strength varies depending upon the thickness of the materials being fixed together.

A summary of the factors involved in these variations is set out below, and for a more detailed account, you can access our technical data sheets via the menu at the top of the page.

If there are any questions remaining about the testing data, fell free to contact us with an enquiry via the contact details at the bottom of the page, or by clicking here to send an email.

What is Tensile Strength

This is a measure of the pull-out force needed for the bolt to fail when a tensile load is being applied.

What is Shear Strength Over Thread

This is a measure of the force needed for the bolt to fail when the shear plane falls over the threaded section of the bolt. The shear plane is the area produced by the two materials which the bolt is clamping together.

what is Shear Strength Over Slot

This is a measure of the force needed for the bolt to fail if the shear plane – the area covered by the two materials being clamped together - falls over the Blind Bolts slotted portion. If the correct vertical alignment has been used, then the Blind Bolt will have been installed with the slotted portion close to the anchor.
