Tighten the bolts to maximum 0.94-1.23 kgf.cm / 0.09-0.12 Nm / 0.81-1.06 in.lbs torque with 4mm Allen Wrench...my mini torque wrench goes up by a factor of 1 Nm increment at a time...I couldn't find 0.09 Nm on there with a microscope This is a non-critical fitting, bolts go into preset alloy threads in the carbon assembly. So feel tells me when they are tight enough...and about 25 years of experience

I do use a torque wrench for pretty much everything else...Got one, might as well use it
