Method for removing a two-part connector in a workpiece arrangement

A method for removing a two-part connector in a workpiece arrangement, comprising:

• providing a workpiece arrangement having a first surface and an opposite second surface and having a hole which connects the first surface to the second surface;
• a connector in the hole, the connector having a bolt and a sleeve fastened to the bolt;
• the bolt extending along a centerline between a first end on a side of the first surface and a second end on a side of the second surface of the workpiece arrangement;
• the bolt having a head portion with a diameter that is greater than a diameter of the hole, and has a shank portion, a diameter of which is less than or equal to an inside diameter of the hole, wherein, as seen along the centerline, at least a part of the shank portion that projects from the workpiece arrangement on the side of the second surface has retaining grooves that extend at least predominantly in a circumferential direction;
• wherein the sleeve is fastened to the bolt on the side of the second surface such that its inner surface engages with the retaining grooves and prevents relative movement of the bolt and sleeve parallel to the centerline;
• and
• wherein the sleeve has an outside diameter that is greater than the diameter of the hole in the workpiece arrangement;
• cutting the sleeve and or the bolt;
• and
• removing the connector from the hole.
