Help identifying rivet type

[Latiguy]

Can anyone help me identify this type of rivet? I would like to find out who sells these but don't know where to start or even what they are  called.

Thank you!

Tube rivets. There is a special tool that splits the end to make it hold.

Some places will list them as splash rivets. FWIW the hand setters do a pretty good job of splitting and clinches the splits if you just have a few to do and don't want to buy dies for a press riveter.
