The OP is asking about the collar. The torque was reduced from 6.2 Nm to 4.0Nm.. The locater screw at the front of the steerer tube is 1.0 Nm with using Loctite 242.
Note: The collar has a Allen head steel bolt that threads into a steel cylinder nut. The bolt, nut and shank should all lubricated with a high quality grease. The plastic cap cover that has a hole in it for access to the clamp, has 6.2 Nm marked on it. Specialized did not issue a new cover, so I used a black felt tip marker and covered the old torque (6.2Nm) and made a small Brother label maker sticker with the 4.0Nm torque. Just so no one over torque's the collar. The service letter does not include this information. I got this from the shop letter.
