Tightening torques for screw and bolt connections
Bolt locking devices
● Refit nuts or bolts that are mounted together with locking, resilient, and/or force-distributing
elements with identical, fully-functional elements when re-assembling. Always renew keyed
elements.
● When screwing together threads secured with a liquid adhesive, use a suitable medium
such as Loctite 243.
● Always use suitable securing devices or removable adhesives (e.g., Loctite 243) when
installing fixing bolts with a clamping length of less than 25 mm. The clamping length is
taken as the distance between the head of the bolt and the point at which the bolt is screwed
in.
Tightening torques
The bolted connections with metal contact surfaces, such as end shields, bearing cartridge
parts, terminal box parts bolted onto the stator frame, should be tightened to the following
torques, depending on the thread size:
