260DET Posted August 2, 2013 Share Posted August 2, 2013 Recall some vague discussion ages ago on what these numbers represent, a recent search showed that some car business people were stating categorically that the numbers were assembly torque settings. Well they are not, see chart below from a Subaru FSM. Quote Link to comment Share on other sites More sharing options...

Tony D Posted August 5, 2013 Share Posted August 5, 2013 (edited) Not Torque, tensile grade. I see the Nissan TSB was posted, let it speak for itself. (INDIRECTLY it is a torque indicator, but only in the context of finding 75-80% of yield to properly clamp a joint!) Torque is a terrible indicator of fastener state. Universally high stress joints have moved to ksi/stretch monitoring for critical fasteners. Too many variables using "torque"!
