"WebThread shear is an important failure mode for a bolted joint, and it occurs when the threads shear off of either the bolt (external thread shear) or off of the nut or tapped part (internal thread shear). There should be enough engagement between the bolt threads and internal threads that the bolt fails in tension before the threads shear. " - Roymech screw threads
