A screw picker is a small tool used to handle small screws during small intricate repairs. The screw picker has a small claw that can be extended and grasp the small screw to twist it in place.

presuming you mean the lead screw on a lathe, used when cutting threads on the workpiece, then the screw itself is obviously fixed, but the rotation of it may be able to be changed, depending on the lathe manufacturer.
The pozidrive screw is a modified phillips head screw that can be used in almost any application. It has 4 additional cuts in the head and it takes a special tool to remove them although a regular phillips head screwdriver will work if they are not very tight.
Cant say from experience with this particular model whether it is an air or fuel screw, however; If there is only one screw then it does both. If there are 2 others near it then one does the air, the other two do the fuel. The factory standard setting for the main idle-adjustment screw on most bikes is 1 and 1half turns out from closed position. This is often the case with the other adjuster screws as well, but the mixture will need to be altered as the engine wears.
