I wanted to share a very successful procedure to remove one of the flat head 4-40 cover screws from my K3. The screw head was damaged beyond use. There was a long thread on the subject last year and one poster suggested using a left hand drill bit. I purchased a 3/32" left hand bit, chucked it into my hand drill, masked off the screw to avoid any cover damage, drilled very slowly, and 5 seconds later the drill bit with the entire screw was in my hands. The threads of the 2-D fastener were totally undamaged and a new screw was easily put into place. My thanks to the poster that made the recommendation.
