Need to start a screw in a hole or recess and don't have any sticky stuff ? Some mechs call it dum-dum. Then try this tip. Take a magnet , an old speaker is perfect. Stroke the screwdriver along the magnet in one direction , not back and forth. Between 6 and a half dozen times should do it. The screwdriver wll stay magnetized for a short time or untill you drop it. Will not work on aluminum screws , unless of course you have an aluminum magnet.
