  • the snap ring is such is compressed that the bevels of the Do not protrude ends over the edge of the recess, so that a secure hold of the tool in the Hexagon socket not guaranteed in all cases is.
  • the spring ring is a helical spring-like Swirl forms. That means the spring ring is in interlocks, with the ends of the preferably open spring washers in a laterally offset opposite layer are located. By intertwining the Spring washers, the winding of which along an imaginary one Helix runs, this is supported resilient at least in some areas on the side walls the recess. This makes it a safe one Fixing the spring ring in the recess realized.
  • the Recess on one level being a normal of this Plane with a longitudinal axis of the actuating tool coincides. So the spring ring runs on a concentric circular path around the longitudinal axis of the tool.
  • the recess as a substantially rectangular or U-shaped Groove is formed. This allows the interlaced spring washer at least in some areas support the legs of the groove. So he keeps his Position in relation to the tool longitudinal axis.
