Torque Specifications
Use as a general guide only. In most cases, you can use the grade 6 ratings for nut & bolt applications. Be aware of the materials you are fastening into, as this affects the safe torque range. Example: The 1/4" primary bolt that threads into the alloy transmission housing should not be torqued to 10 ft/lbs or you may strip the threads.
