Blind Bolt Testing Terms Explained

Blind Bolt Testing Terms Explained

Due to the unique design of the Blind Bolt there are a number of different fixing combinations possible. Although the tensile strength of the Blind Bolt remains constant, the shear strength of the Blind Bolt can vary depending on the thickness of the material being clamped. These variations are explained below.

Use the menu to see an explanation of the testing criteria found on our technical data sheets. However, if there is anything that you are unsure about please feel free to contact us on the number below or click here to send us an e-mail.

Tensile Strength

This is the ultimate pullout force required for the bolt to fail when under a tensile load.

Shear Strength Over Thread

This is the ultimate force required for the bolt to fail when the shear plane, produced by the two materials being clamped, falls over the threaded portion of the bolt.

Shear Strength Over Slot

This is the ultimate force required for the bolt to fail when the shear plane, produced by the two materials being clamped, falls over the slotted portion of the Blind Bolt near the anchor when the bolt has been installed in the correct vertical alignment.
