The riveting defect in the figure shown is
- excessive hammering on the rivet head.
- the dolly was held at an angle.
- the snap was not square.
Explanation from PART66Online
The head formed by the snap is lopsided: it sits off-centre on the shank, seated hard against the skin on one side and lifted clear of it on the other. That is what happens when the snap is not held square to the rivet. Excessive hammering flattens or cracks the head evenly instead of tilting it, and a dolly held at an angle would spoil the manufactured head on the other side of the joint, which here is square.
