Tightening torques for stress bolt connections to MTN 5007 standard
This standard applies to stress pin bolts and stress bolts which are subjected to static and dynamic
load of strength class 10.9 as well as to the associated nuts.
Shank and junction dimensions to MMN 209 standard and material and manufacture to MMN 389
standard (bare metal or phosphatized).
The values in the table are based on a friction coefficient µtot = 0.125.
Threads and mating faces of screws and nuts must be coated with engine oil prior to assembly.
An assembly tolerance of +10% of the figures in the table is permitted due to unavoidable deviations
during the tightening process.
The figures in the table are for hand-tightening using a torque wrench.
