Blind Bolt Testing Terms Explained

Blind Bolt Testing Terms Explained

Blind Bolts feature a unique design and an innovative range of fixing combinations.The tensile strength of every blind fixing, from thin wall bolts to heavy duty bolt, remains constant, but the measure of the shear strength can vary.

Factors which might impact upon the strength of any hollow bolts will primarily depend upon the thickness of the substances being fixed together.

The terms used to explain this are set out below.

Detailed information on these issues can be found on our technical data sheets, and if you still need to know more please feel free to contact us using the details below or by sending us an email.

Tensile Strength

This term describes the force needed to cause a bolt to fail when it is handling a tensile load.

Shear Strength Over Thread

This term describes the force needed to make the bolt fail in cases where the shear plane, derived from the two materials being fixed, falls over the threaded section of the bolt.

Shear Strength Over Slot

This term describes the force needed to make the bolt fail in cases where the shear plane, derived from the two materials being fixed, falls over the slotted section of the Blind Bolt. This applies if the bolt has been fixed using the correct vertical alignment and the shear plane is near the anchor.
