Hi Alessandro,

The “size” of the rivet (i.e with your question, 5.2mm) equates to the diameter of the rivet head, not the mandrel (aka “shank”).

So, whether or not this product will rivet your 5.2mm rivet depends on the diameter of the mandrel of this 5.2mm rivet.

As this product is able to rivet the larger 6.4mm rivet, it should do your 5.2mm rivet with either the 4.8mm or 6.4mm nozzle (aka die).
