Bosch Premium 3410

[QuangTeo]

I found the information of Bosch Premium 3410 on Bosch's homepage. I see they have threads size M22x1.5-6H. I don't know, what is difference between M22x1.5-6H and M22x1.5.
What is 6H ? I can use it instead for M20x1.5

6H is the thread tolerance.
You cannot use an M22x1.5-6H where an M20-1.5 is called for.

See here for an explanation.

Oh . Thanks you.
I wrote mistakenly, instead for M22x1.5 not M20x1.5

Yes, you can use an M22x1.5 and an M22x1.5-6H interchangeably because for the purposes of this discussion, they are the same thing.
The 6H call out is a thread tolerance that is usually not included in the information provided to the customer because it tends to cause confusion. The tolerance is an engineering reference and it will have no impact on you usage.
