Heromount tools are sized to make rivets from AWG copper wire. AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors. The American Wire Gauge chart is based on the number of dies originally required to draw the copper down to the required dimensional size. It means the higher the AWG number is, the smaller the wire diameter is.  This is the size wire you will find in Home Depot or Lowes and other home improvement stores

 

Rivet diameters are from AWG copper wire are as follows:

4 gauge wire is .204" diameter
6 gauge wire is .162″ diameter and is approximately equal to a #9 belt rivet
8 gauge wire is .128″ diameter and is approximately equal to a #12 belt rivet
10 gauge wire is .102″ diameter and is approximately equal to a #14 belt rivet
12 gauge wire is .081″ diameter
14 gauge wire is .064″ diameter
16 gauge wire is .051″ diameter
