Is Trailer Suspension U-Bolt Plate Supposed to Bend and What is Torque Spec for 3/8" U-Bolts

Question

Question:

So, I noticed in the video the spring plate does bend when tightened. How much torque was used? This is normal on the spring plates? They should bend slightly? I freaked out after I noticed my bent. But this is how it should be?
