Conical screw extractors with 3/8" square drive fittings. Dimensions: 2, 3, 4, 6, 8 and 10 mm. For easy removal of damaged and broken right-hand thread bolts and screws. Once a hole is drilled in the seized screw end, the left-hand threaded screw extractor is inserted, after which the screw/bolt can be unscrewed 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. Supplied in an injection-moulded plastic case.
