Screw Extractor Set, 6 parts
Conical screw extractor with 3/8" square drive. Dimensions: 2, 3, 4, 6, 8 and 10 mm. For easy removal of damaged and broken right-hand threaded bolts and screws. Drill a hole in the seized screw end, insert the left-hand threaded screw extractor, and unscrew the screw/bolt along its own thread. The process does not damage the screw hole thread at all. Can also be used on damaged hex screws without drilling.
