Fasteners with continuous tool holder

Abstract

The invention relates to a fastening element (80) for a pallet device (2) which is designed to fasten a lower part (60) to an upper part (20) by means of a rotation about an axis of rotation (RA) at least relative to the upper part (20).The fastening element has an insertion section (88) to be inserted into a lower part fastening recess (72) of the lower part (60) in a receiving direction (AR), which comprises a base body (90) and a rotational engagement device, which has at least one rotational engagement element (92) projecting radially from the base body (90) in such a way that it can be brought into engagement with an upper part rotational engagement element (48) of the upper part (20) by a rotation of the fastening element (80), and a head section (84) adjoining the insertion section (88) opposite to the receiving direction (AR), which extends further radially away from the axis of rotation (RA) than the insertion section (88) and is designed to bear against a pressure-bearing surface of the lower part (60) facing away from the upper part (20) and surrounding the lower part fastening recess (72), and a tool receptacle (86) extending in the receiving direction (AR).According to the invention, the tool holder (86) extends axially at least in such a way that it is intersected by a central plane (ME) perpendicular to the axis of rotation (RA), which is equidistant from the head section (84) and an end (94) of the insertion section (88) facing away from the head section (84).
