This is all well and good IF the receptacle has an intimate contact with the box if it's metal. The ground path shall NOT rely on the 6-32 screw for a ground! Most likely the receptacle is floating above the box about an eighth to 3/16" and NOT in intimate contact with the box.
IF the box is grounded through the BX armor, then it is better to use a ground pigtail with a screw in the 10-32 tapped hole.
