Tightening torques for metric fine threads
The tightening torques specified below apply only
when:
– A friction coefficient of µ tot = 0.14 is achieved in
connection with thread lubricant.
To achieve this, a surface protection agent such
as A3C+L, Dacromet or Termosil is
recommended.
– No other tightening torque is specified in the
descriptive text.
– No additional screw retention is used, such as
MK-type bolts or liquid locking compound.
