I have always heard that non-metal tools must be used for alignment. The presence of your hand capacitance close to RF circuitry is bad enough. Putting ferrous metal nearby in the form of a screwdriver pretty much louses up your adjustments. If you need to, you can make an alignment tool from a piece of plastic rod (some cocktail sticks are sturdy enough) or even from a chopstick. Just file/sand the ends down to a screwdriver shape.
