What are the bents for?

I have a few of these. I don't know what to do with the bents. Are they just visual marks so they're not confused with caps?

Probably to keep them away from the PCB.

As the current approaches (or exceeds) their cut-off, they will physically expand due to heat breaking the circuit.  By making sure the element is away from the PCB, it won't have a heat-sink effect.

I think they're a form of retention to keep the part in place while it's being soldered.

I have caps that look the same, it just allows you to "snap" them into a board

though I could be totally wrong

They put those there to make the part look cooler and mysterious.

I believe it is what osleg said.Not sure but its common on a lot of through hole parts, so it's not to differentiate it from a cap. There are plenty of caps with these bends in them.

Thanks. I see. Well, in my case I forced it into a couple of holes for a diode. :)
