Centurion Turbo build

Hey all, doing a build of this frameset I picked up from a fellow forum member.
I've got most of the parts on hand with the exception of a seatpost and accompanying binder bolt.
From doing a bit of research, I've gathered that the seatpost size is 27.0 and I'll need a binder bolt w/out the key.
However, all the binder bolts online seem to have the key. Anyone have a source for the keyless bolts or any suggestions?

Hope everyone is having a safe quarantine.
-Rafael

My '84 Turbo has a 27.2 seat post. The Ironman takes a 27.0. My binder bolt has a slotted ribbed nut with an Allen key bolt. I can't help with that but to suggest Dremel. You will luv your Turbo. I've never had the fortune to ride a Tricolor group but it likely is perfect for the Turbo.

edit: looking at your pictures again: you should use some Rustoleum Rust Remover on the fasteners of your Tricolor bits and baste your frame also.

It looks like the same bolt as on my son's bike, an '89 Club Fuji. He's got it with him at school, so I can't measure the size. The bolt looks like a standard 6mm, but I don't know where you would find a nut like that. Turning down a hex nut might be the easiest option. Next would be drilling and tapping a piece of bar stock.

Thanks for the good info, guys. Looks like the bolt length has to be just about exact for that setup?

for anyone wondering. The background is the T.V. box the bike is leaned up against.

oh I have had this problem before. "fixed" by doing quite a bit of grinding. take a standard bolt then grind off key, then grind key side to the correct length, then use a different bolt (without the sleeve.. the sleeve wont fit- thus the need to grind the other side down). The other option is that hardware stores - good ones- may have just what you need. I only did all that grinding because I had some old bolts around and a grinder.

If all one has is hammers and screws...
