This extra-long Screw Guide works over the outside edge of rain gutter to hold and guide 1/4-inch hex head screws up to 2 inches long. An impact grade 6-inch long power drive, with a 4-1/2 inch anodized aluminum sleeve, provides easy reach to the mounting surface of eaves without marring the finish of the outside gutter edge. The power drive's hex shank fits any drill or 1/4-inch impact driver and the aluminum sleeve guide ensures support for fast, accurate screw starts and for stabilizing long screws, at any angle, during installation. A permanently bonded, spring loaded magnet keeps the hex head screw fully engaged in the power drive. The screw seats flush every time and the magnet will not fall out.
