A.1 Tightening torques
A.1.1 Tightening torques for screw and bolt connections
Bolt locking devices
• When assembling, ret nuts or bolts that are mounted together with locking, resilient,
and/or force-distributing elements with identical, fully-functional elements. Always renew
keyed elements.
• When screwing together threads secured with a liquid adhesive, use a suitable medium such
as Loctite243.
• Always use suitable securing devices or removable adhesives (e.g., Loctite243) when
installing xing bolts with a clamping length of less than 25mm. 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:

The tightening torques stated above apply to screws with property class 8.8, A4-70 or A4-80
according to ISO 898-1, however only to bolts screwed into components made from materials
with the same or higher property class, e.g. cast iron, steel or cast steel.
