Had to drill a bunch of these out to get the body panels off my car. The look like a normal (large) pop-rivet on the outside, but on the inside the cylinder split into 4 tongues that curled outwards. I suppose the idea is to give a larger bearing surface on the blind side.
I'll need about 50 of 'em.
Hanson has "T rivets"
Or did you mean a drive rivet?

That's them.
Those look nicer.
Has anyone use these enough to recommend one variety over another?
Try google... blind rivet peel type. These sound like they are used in the auto industry
The T rivets are used where you need maximum strength, the Tri rivets are used in soft material like plastic to prevent pull through.
I have seen the T rivets used to hold window regulators in a car door, and if I recall these were 1/4" diameter and you needed the pop rivet tool that looks like a tree branch lopper to set them.
Mine were used to hold FRP panels together. I think I'll get 3/16 T ones, and hope that my good but not tree-lopper-size rivet tool will work.
If it doesn't, see if you can get ahold of one of these "lazy tongs" style riveters:
Someday I'll get the time to sit down and figure out how they work. I've got a feeling a little analysis will show it's the equivalent of a two handled "branch lopper" type with handles equal to the combined length of the lazy tongs links. (Or maybe it's half those links.)
