What is the name of this old PC game?

I used to play this game where you were this little alien-looking guy on top of a screwdriver and your objective was to unscrew the pattern of screws on the screen. (almost like pacman but with screws instead of dots and 3D). There were obstacles and enemies in your way so you kind of had to navigate around while unscrewing all the screws.

I’ve been googling for a while and am coming up with nothing. I saw a yahoo answers question that sounds like exactly what I’m talking about, but the answer was inaccurate. Can anyone help me?
