When a shear stress (τ) is applied, some plane can slip and a dislocation can be formed. In Figure 3457, the slip of the elements has started on the right-front face of the crystal and then, in the direction of the shear the progressive slip on the slip plane involves the motion of a right-handed screw dislocation.
