Look up torque and corresponding axial force by bolt size and strength class (8.8, 10.9, 12.9).
Reference tightening torques and resulting axial preload forces for metric coarse-pitch fasteners by strength class. Values are for dry, lightly oiled threads as typically listed in assembly tables—always follow your product manual, joint design, and lubricant instructions for safety-critical bolting.
