Each fastener should be tightened to the torque specified. If no description or specification 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 fastener.

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.
