1. Tightening Torques
• Tightening torques are roughly classified into the following two categories:
• Fasteners used in a location denoted by “wet” should always be tightened in a wet condition (lubricated with en-
gine oil or grease). Any other fasteners than those so specified should be tightened in a dry condition.
2. Table of Standard Tightening Torque
• Threads and bearing surfaces shall be dry (tightened in a dry condition).
• If the mating nut and bolt (or stud bolt) are different in level of strength, tighten them to the torque specified for the
bolt.
• Automotive screws refer to coarse screw thread with nominal diameter of 3 to 8 mm or fine screw thread with
nominal diameter of 10 mm or larger.
