A holding screwdriver is a useful tool in many applications, because sometimes no matter how you try, you can’t hold the screw yourself. So last year Wera introduced the Screw Gripper, an accessory that turns any of their screwdrivers, and probably most other brands, into a holding screwdriver.
The compact elastomer accessory slips over the the screwdriver tip of screwdriver. Two flexible grippers grab the screw while you’re getting the screw into position. When the grippers contact the surface, they will spread apart, moving out of the way of the screw head, which allows you to finish driving with the same driver, even if it’s counter-sunk or counter-bored.
The only place I could find these screw grippers for sale was online at Sears. There they are part of a set with two Lasertip screwdrivers that runs $30.
