While the OD of the rivet is probably larger than .1875" exactly, there is still some play between the rivet and the hole when it hasn't been crushed yet.

I use Cleco fasteners and Cleco clamps and haven't had any issues. The only time something was loose was if the rivet hole itself was marked wrong or sized incorrectly from the laser cutter.
