摘要

The socket has six blade-like cutting edges for cutting a hexagonal bolt in external edges, where the socket has no internal hexagons. An inner diameter of the socket tapers upwards around 6 degrees. The cutting edges are straight at a side of the socket and run in a middle of the bolt in a line, where the cutting edges run diagonally in half section of rear edges. The diameter between the opposite cutting edges of the socket accommodates the bolt, and is larger than a bolt head and/or a bolt nut.
