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"

and "Tri-rivets"

Not sure those are generic names.

Or did you mean a drive rivet?

That's them.

and "Tri-rivets"
http://www.hansonrivet.com/w36.htm


Those look nicer.

Has anyone use these enough to recommend one variety over another?

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.

About the time I had mastered getting the toothpaste back in the tube, then
they come up with this striped stuff.

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:

I had the opportunity to use one of those long ago and it was the cat's
pajamas for effortless pop rivet setting. Much easier than trying to
clench your hand on the levers of the more common pliers style tool.

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.)
