Yep, was looking for a link for you, I’d misread your question and answered the torque for a BB.
35-50Nm, so a good amount of power to generate with a 10” Allen key.

Thanks, that is interesting.
I contacted the crankset manufacturer directly that handed me a document where it states "left arm (shim) 12 to 15Nm", I suspected it was for hollow BB and not square for the mention of left arm only and much lower torque compared to what I came across from Parktool or other sources (which seem similar to what you posted, around 35 Nm), but when I raised the interrogation on is it really 12 to 15 Nm, manufacturer did not answer back.
35 Nm seem to be a value that is recommended on several places so I guess this will have to do...!
thank you for the help
I am not sure I understand the answer, so maybe I did not formulate correctly but if anyone have an an idea of the recommended torque for the M8 bolts to install a crankset on a square taper BB, could they tell what is the recommended value?
