When I manual tighten the screws they are as tight as they can get. I would say I have average arm strength but for the life of me I couldn't use the same amount of strength loosening the pneumatic drilled ones. For one screw I had to use a pipe to extend the leverage arm. This was the first time I had to use such measures.
