If the pull is wood, you can predrill, then insert a small finishing
nail, then clip off the head, leaving about 1/8 inch protruding. this
brad will prevent the pull from rotating.

If the pull is metal.....hummm.......maybe you could try spreading 2
part epoxy on the back of the pull. Once it is screwed tight and sets
up, it will do more to prevent the rotational forces than just epoxy on
the screw threads themselves.
