Notes:
This chart is an approximate estimate of torque values.
Always tighten hardware to these values unless a different torque value or tightening procedure is listed for a specific application.
Fasteners must always be replaced with the same grade as specified in the manual.
Always use the proper tool for tightening hardware: SAE for SAE hardware and Metric for Metric hardware.
Make sure that fastener threads are clean and that you properly start thread engagement.
