12.2 Tightening torque values
It is important that the correct torques for fasteners are adhered to. Below are tables of
recommended torques for these. These are to be used unless torques are otherwise
specified. These values are for general use only. Check tightness of all fasteners
periodically. Torque values are in Nm (Newton metres).
