In this APP it’s possible to find the fastener and to define the tightening torque.
For each measure of fastener are specified differents values in accordance to the resistance grade and according to an appropriate coefficient that considers the friction of the under head and of the thread:

• coefficient 0,10: tightening torques for phosphated or galvanized fasteners with thorough lubrication.
• coefficient 0,15: tightening torques for black or galvanized fasteners with minimal lubrication.
• coefficient 0,20: tightening torques for coated or bright fasteners fitted dry
.
Example:
FASTENER: M 10 8.8 GRADE
COEFFICIENT: A 0,15
Consulting the chart select a TIGHTENING TORQUE of 46 Nm
