There isn't remotely enough detail here to make any kind of recommendation/assessment.

It's probably standard rather than metric. If it's not that there's a good chance it's striped.

Very rarely, it's actually the tool itself because the tolerances are incorrect. This only happens with extremely cheap equipment though, and even then it's unlikely.

*Edit - Or are you saying the bolt is seized? Because if that's the case, liquid wrench (or any decent penetrator, really) will make light work of it.

Check to see if it is a Torx bolt.

+1. A number of seatpost makers use Torx bolts for the saddle clamps. Different shape than an allen bolt (aka 'hexagon')

If you have a Guerrcotti, the Alan wrench may not work. You could try a Basso wrench but I know for a fact the De Rosa wrench won't work. Should gone with Campagnolo, he invented the quick release would have made it way easier.

... and if it's not a torx head bolt, you can use a torx bit, bashed in with a hammer, to bite onto a stripped-out allen head bolt.

If you knew the poster's history that issue isn't the problem.

I know I know but I wanted to make an Italian bike joke. I briefly owned a Guerrcotti but ended up stripping what I needed and give the frame to my service manager at the time because he was an excellent employee who rose to the challenge quite quickly and he really wanted it. He still has it last I talked with him but he left a little after I was needed at another shop in the company.

That is sufficient justification.
