I am asking because every other car I have ever owned required a bolt/lug torque in the 70-80 ft-lbs range. Clamp loads estimated as 75% of proof load for specified bolts. If the transition point of the torque wrench with 20 pounds was at 26 inches, for instance, multiple that by 20 pounds to determine the amount of torque actually applied: so 26 inches times 20 pounds equals 520 inch-pounds, or 43.33 foot-pounds (520 divided by 12 inches ). Hydraulics Pneumatics 80 150 psi Bolt Torque 40FT-LBS . minimum torque requirement of 105 ft-lbs is specified an increase to 1541 steel would be required. Depending on size, they have a proof load of 580-600 MPa, minimum yield strength of 640-660 MPa, and a minimum tensile strength of 800-830 MPa.
