Weird binder bolt looks like it uses a star shaped tool.

may be simply an allen bolt which has been buggered by someone without the right size key
you could either grab and turn the head or go at it with a screw extractor - may need to grind the tip of the tool down a bit

Seems the addition of the rack demanded a longer bolt and that's what was handy. Likely takes standard keyed bolt?

You could always try Vise Grips. Or an axe.

Still, hangers came keyed on many bikes. I'd put a vice grip on it and replace accordingly.

You got the correct answer in post 4. It does not take a standard allen wrench. It's a good excuse to spend $20 on more tools.

That bolt looks like it had a long and happy intense relationship with the frame. I have never heard of or seen somethig else than a standard allenhead or hex bolt being used at that point, certainly not on a bike that old. Anyway, from the looks of it its a goner anyway, just drill it out...

Merz used some of it and they are not hard to deal with, no need for excessive force that could damage the frame.

Add a few drops of penetrating oil to the threads the night before attempting the removal. Can't hurt.

I don’t think I ever realized these were actually different from Torx bits. However I think my only experience with them was the axle on ‘83ish Golf and I just hunted down the Snapon guy and bought what the Chilton told me to get

...someone really went to town with that respray - doing up the Rampinelli frame pump to exactly match the scheme of the frame - looks like they had lots of good fun with their Cesare...

Those particular binder nuts turn up on old bikes from time to time, and use a 1/4" Allen key btw.
Not sure who made them.
Threading should be 1/4-20 iir.

Has anyone ever seen an SAE triple square? I though they were a strictly metric, mostly VW thing, which is why I bought a set. I had to teach the sales guy at Autozone about them.

Harbor Freight has a 100 piece "security bit set" that should have them.
