Question

State the condition when axial tensile failure of bolt occurs

Answer 1

Explanation:

Failure modes of bolt and nut assemblies under tensile loading. Thread failure of bolt and nut assemblies subjected to tension is generally undesired because it is a less ductile failure mode than fracture of the threaded shank of the bolt (denoted bolt fracture).

Answer 2

Answer:

There are at least five causes of loose bolts, which can occur separately or in combination: Under-tightening. ... This can lead to sideways slippage between sections, placing unwanted shear stress on the bolt that could eventually cause it to break. Vibration.
