For the 9/16 inch diameter shackle bolts included in the Redline Triple-Axle Trailer Hanger Kit # APTT5 referenced in your question, you will want 65 to 95 foot pounds of torque.

This kit can be used to attach 6 leaf springs to your trailer frame. I have also included a chart that will help you determine the hanger location based on the type of leaf springs you have for your trailer.
