Should we add the washer at the head per section 5.20?
Happy New Year!
Not in this case. In this case you hold the bolt and torque the nut so the nut has a washer.
5.20 is referring to a case where you must torque the bolt head. In that case you need a washer under the bolt head. Think bolt going into a blind threaded hole or a nutplate.
