Internal hexagon socket wrench insert

Abstract

An internal hexagon socket wrench insert (30) having a drive side (31) via which the internal hexagon socket wrench insert (30) can be connected to a hand-, pneumatically or electrically driven tool to transmit a torque to an internal hexagon drive (32) connected to the drive side (31), wherein the internal hexagon drive (32) comprises a plurality of drive parts (33) which are spaced apart from each other at an angle of 60 degrees in the form of a closed ring and thus form a drive profile which can be placed on a corresponding drive head (41) of a screw element (40), characterized in that a first contact point (331) of the respective drive part (33) adjoins a first flank (332), wherein the first flank (332) transitions into a first arcuate recess (334) such that a second contact point (333) at the transition point;that the first arcuate depression (334) transitions into the second flank (336) in such a way that a third contact point (335) is formed at the transition point; that the second flank (336) transitions into a second arcuate depression (338) in such a way that a fourth contact point (337) is formed at the transition point; that the second arcuate depression (338) transitions into a third flank (339) in such a way that a fifth contact point (340) is formed at the transition point; and that the third flank (339) terminates with the other end of the drive part (33) in such a way that a sixth contact point (341) is formed at the termination point.
