Abstract

A fastening arrangement may include a first component having an undercut groove, and a second component having a through opening. The second component may be couplable on the first component via a fastening device configured to be guided through the through opening and engage the undercut groove. The fastening device may have an axis oriented perpendicularly to the undercut groove. The fastening device may include a hammer head element and a holding element. The hammer head element and the holding element coupled thereto may be rotatable about the axis in an unrestricted manner when mounted on the second component. The hammer head element may have a plurality of orienting contours configured to set an orientation of the hammer head element relative to the undercut groove such that the hammer head element is dippable into the undercut groove independently of a rotary position of the hammer head element about the axis.

Abstract

A method for making a blind hole may include arranging a workpiece in a negative form with a first portion and a second portion. The first portion may include a recess. The second portion may include a guide for a punch. The recess may be arranged substantially coaxially to the guide. The method may also include displacing a material of the workpiece into the recess via pressing the punch into the workpiece. Additionally, the method may include pressing the punch into the workpiece in a first movement section with a first velocity. The method may further include further pressing the punch into the workpiece in a second movement section with a second velocity such that the material is sheared and is partly extruded into the recess. The method may include moving the first portion relative to the second portion and shearing off the material displaced within the recess.
