This deluxe rivet setter which is included in this set has a wider diameter head that sets the medium rapid rivets and medium double cap rivets perfect without any chance of leaving a ring on the cap. However for the rapid rivets and double cap rivets that are large and extra large, this deluxe setter is very close the diameter of the cap so you have to be exactly centered so not to leave a ring imprint on the outer edge of the cap.
The snap setters included work perfectly for setting the line 20 and line 24 jacket snaps. There is also a setter for line 16 segma snaps.
