Standard Tightening Torque
Each fastener should be tightened to the torque specified in each section. 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 following chart.
• The following chart is applicable only where the fastened parts are made of steel light alloy.
