I use a 3" deck screw, make sure you hit the center of the stud, and slightly angle the screw downward, abd make sure you drive the screw in far enough so that your mount does not slide down and foward when you set it on there. It should not move at all once you let go.
Tips for hitting a stud:
1: buy a studfinder and put a little pencil mark where the right light starts and stops, and make sure it is 1.5" wide and put it in the middle.
2: measure over roughly 17" away from the side of a electrical outlet and use your stud finder or tap on the wall.
3: measure over roughly 17" from a corner, this does not always work! depends on windows, doors, etc...
