Three‐dimensional photoelasticity has been used to examine the effect of eccentric loading on the stress distribution along the helix of the roots of threaded fasteners. In the investigation the ratios of axial to bending stress were similar to those found commonly in engineering components. The results showed that, as the level of eccentricity increased, the maximum stress in helix of the thread root did not change significantly, but there was an increase in the length of helix which experienced high stress. This will lead to an increase in the probability of crack initiation and propagation in the presence of eccentric loading.
