Ok,
But I have some issue with Surly 30.0mm Stainless Steel Seatpost Clamp
Stainless Steel Seatpost Clamp | Parts | Surly Bikes

Actual inner diameter of clamp is approx. 30.5mm (when clamp bolt is in line with its counterpart thread), but actual outer diameter of seat tube (in tight close position) is approx. 29.5mm. So the clamp bolt has repetitive bents and finally become broken.
Now I am using handmade 0.3mm shim from shaving gel ballon between seat tube and clamp, and the bolt sits straight!
