STANDARD TIGHTENING TORQUE
Each fastener should be tightened to the torque specified in each section of this manual. If no description or specifi-
cation is provided, refer to the following tightening torque chart for the applicable torque for each fastener. When
a fastener of greater strength than the original one is used, however, use the torque specified for the original fasten-
er.
NOTE:
For the flanged bolt, flanged nut and self-lock nut of 4T and 7T strength, add 10% to the tightening torque
given in the chart below.
The chart below is applicable only where the fastened parts are made of steel or light alloy.
