Torque Spec for Nuts that Attach 10 inch Trailer Brake Assemblies

Question

What is the recommended torque specification when installing the nuts on the mounting bolts to the axle for 10 inch brake assemblies on a 3500 pound axle? In general 7/16-20 plated nut would be about 45 ft. pounds, is that correct? Thanks,
