Selecting the tools
Outer ring
The screw heads (1) are easily accessible for fitting a socket wrench.
Therefore, you can use manual or mechanical torque tools (electric or
hydraulic screw drivers).
Inner ring
The screw head (1) is accessible only via the opening (2). An extension (4)
is required for fitting a socket wrench (3).
A manual torque tool (5) is recommended so that it can be tightened gently,
and slipping from the screw head (1) is avoided.
