Tightness classes for bolts with untreated, unlubricated
surfaces.
The values provide for a 90% use of tensile limit with a coefficient
of friction µ =0.14.
(gas)
The maintaining of the tightening torque will be checked with
torque spanners.
The use of MoS2 lubrication will not exceed the given values.
Important
Self-locking nuts must be renewed after each dismantling.
6.6.3 Bolted connections
With vibration equipment it is important to check the spacing
between the fixed seatings. Observe the tightening torque.
6.6.4 Rubber buffer
