Hello all, I would like to replace the stock steel hardware on my deda superzero carbon post with titanium bolts. Although I can find titanum bolts easily, the heads do not match the heads of the deda bolts which are slightly rounded near the threads, where they press against the bottom of the seatpost. So, I thought that I could just use a non-taper titanium m6 bolt with a domed washer. Where to find something like this?

Alternatively, if you know who makes a bolt which approximates the deda shape, that would help too.


this is a picture of deda bolts WITH rounded washers from another thread. These are not the bolts that I have but these are exactly the washers I need.

I have the same seatpost, V brake washers won't work, they're too flat,
they really need to be hemispherical washers so the bolts can rotate without chewing up the carbon,
don't know if you can get them here but this is what they'll look like-

Yeah it's it's odd that they call it an m6 washer but it has an m8 bore?
more googling throws up this http://www.avonstainlessfasteners.co.uk ... -a2-and-a4
12mm OD, box of 50 though.
