BOLT TORQUE SPECIFICATIONS (GENERAL GUIDE FOR METRIC
FASTENERS)
Use the “Standard Torque” charts as a general guide when tightening fasteners that DO NOT HAVE
SPECIFIC TIGHTENING RECOMMENDATIONS
Key to table above:
*
NOTE: The size is the diameter of the shank - not the head width.
**
NOTE: Mild steel torque values to be used for SAE Grade 5 bolts when weld
nuts, or other low strength nuts are used.
***
NOTE: Use these values when any of the following conditions exist:
1. Possible damage to the joined members of the assembly may occur.
2. Thick and/or highly compressible gaskets are used between members.
3. Non -flat unmachined seating surfaces for bolt head (or nut) occurs.
4. Non -flat or non -parallel joint faces are encountered.
****
NOTE: Use these values when ALL of the following conditions exist:
1. Damage will not occur to the joined members of the assembly.
2. It is desirable to use this higher clamping force to ensure tightness.
3. Fastener thread is not lubricated prior to assembly.
