Mercedes boss Toto Wolff is all too aware of the importance of Hamilton edging his nose in front of Vettel, and did not seem overly optimistic about his team's chances in a fortnight's time: "Every bit of momentum is important". Ocon took a solid fifth place for Force India while Felipe Massa challenged Stroll for sixth at the end but ultimately settled for seventh.
Hamilton's pole moves him one ahead of Ferrari legend Michael Schumacher and it was a performance worthy of such a momentous achievement. Vettel said. "My start was not so good - I had quite a lot of wheel spin and we didn't quite have the pace of the leading two cars but seeing the people and having that support was unbelievable".
The session's start was delayed because of standing water on the Monza circuit and rain fell even when drivers were finally permitted to come out.
"But if you were in that negotiation process with a team then that's the first thing you'd talk about: equal equipment, no playing second fiddle".
But he saved the best until last. Red Bull's max Vestappen came second and he was 1.148 seconds behind Hamilton. "I'm going to have some pasta tonight to celebrate", F1 official website quoted Hamilton as saying.
Can Hamilton seize opportunity?
Hamilton has now won six races this season, and coming on the back of last weekend's success in Belgium he is the first driver to have back-to-back wins in 2017.
A satisfied Valtteri Bottas narrowly outshone his Mercedes teammate Lewis Hamilton, with Ferrari close behind, in Friday afternoon's second free practice for this weekend's Italian Grand Prix at Monza.

She and Japanese Defense Minister Itsunori Onodera met on the Izumo at a naval base in Yokosuka, south of Tokyo . As she arrived in Japan , Mrs May said: 'We are very clear that the actions of North Korea are illegal.
But of more pressing concern for Hamilton is that of dealing a psychological blow in Vettel's direction at his Ferrari team's home race.
Vettel has team-mate Kimi Raikkonen one place ahead of him on the grid.
Just after Bottas set the leading time, Hamilton had a faster pace before dropping time in the final sector. "I was surprised by how quick the others went".
"We knew it would be a hard race, perhaps we expected to be closer".
But he said he was confident of recovering in the race.
He also said: "It's that's very clear in the rules: when two cars are side-by-side at the chicane and one gets to take it and one doesn't, you give back the position, but this time the FIA must have been having a Heineken".
Stroll and Ocon may not be easy for the Ferraris to pass.
