The usual recommendation for the shop head is to use a rivet that extends 1.5 times the diameter. See here:How to select the correct rivet size atlascopco
But it's much easier to drive when the rivet is less than that recommended 1.5 times the diameter.
I don't see how it would make too much difference in strength. So my question is if there is any data or criteria about using a smaller shop head thickness? I shot some at 1.0 times diameter and they looked fine. But didn't load test them. However, it seems to me that almost any size shop head is equivalent to a flush head....
And does the DAR inspect for this rivet criteria?
