There is actually not a recommended torque spec but I do have some recommendations.
-Make sure the bolt is tightened as close to the truck bed side as possible (there is a slit that allows for side to side adjustment on top of the mount, make sure its as close to the bed side as possible)
-Utilize new lock nuts, technically the nylocks are one and done so get some 1/2" nylock lock nuts
-Good n tight is typically tight enough but you can use some crosscheck torque seal to monitor whether or not the nut is loosening
