Finder
Metric Bolt Torque Finder
Select a metric coarse bolt and ISO property class. The finder scales the site torque table by nut factor so dry, lightly oiled and lubricated estimates can be compared without turning this into a full joint design worksheet.

When to use the full calculator
This finder is a fast chart view. Use the bolt preload torque calculator when you need custom diameter, pitch, target preload or nut factor inputs. For strength checks, use the bolt shear strength calculator.
