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