Re: Understanding Bolt Torque vs Clamping Force
Torque value is used to place the fastener in tension after maximum clamping force is achieved.Placing the fastener in tension is the best way to insure the assembly doesn't degrade from heat or vibration.Torque value is determined by testing,causing fastener failure through assembly. The human body is very capable of 'learning' torque values and remembering them,mechanic 'feel' is amazingly accurate given enough repetition.
