There are. Look at the size of the slot in the toggle. It may be the same hardware
but sizing is different.
This does not imply the very tight slot is the culprit, only gives a clue to one of many possible reasons.
Over-tightening of the swaged fitting on the pin is a bit more likely.
I have force opened one of such kit (toggle on pin) and found the pin was not free to move in the swaged wire fitting (which is OK, as otherwise it might fall out when the rig goes slack) BUT should the machine fit it too tight, this will create stress on the perimeter that might end up in a crack exactly as shown.
Ultimately only a material engineer
who understands this design can tell.
