Claims20
A fastener, comprising:
- a threaded shaft,
- a flange part, and
- a head part comprising a center, a periphery, at least three support elements, and at least three groove parts, wherein each of the groove parts are located between two successive support elements and separates the support elements from each other;
- wherein a height of each of the support elements, whose longitudinal axes intersect at the center of the head part increases while extending radially from the periphery of the head part to the center of the head part, and
- side walls on both sides of each support element and intermediate walls connecting the side walls of the two successive support elements facing each other form surfaces in which a drive apparatus is engaged to the fastener for tightening and loosening and a torque is transferred to the fastener.

A drive apparatus, configured to be engaged to a fastener, and comprising:
- a holding part,
- a neck part, and
- a head part comprising a center, a periphery, at least three protrusions, and at least three slots, wherein each of the slots are located between two successive protrusions and separate the protrusions from each other;
- wherein a depth of each of the slots, whose longitudinal axes intersect at the center of the head part, increases while extending radially from the periphery of the head part to the center, and
- side walls on both sides of each protrusion and intermediate walls connecting these side walls form surfaces in which the drive apparatus is engaged to the fastener for tightening and loosening and a torque is transferred from the drive apparatus to the fastener.
2 more elements
A combination of a fastener and a drive apparatus, comprising:
- the fastener comprising a threaded shaft, a flange part and a first head part comprising a first center, a first periphery, at least three support elements and at least three groove parts, wherein each of the groove parts are located between two successive support elements and separates the support elements from each other, and
- the drive apparatus comprising a holding part, a neck part and a second head part comprising a second center, a second periphery, at least three protrusions, and at least three slots, to which at least three support elements are engaged when the fastener and the drive element are coupled with, wherein each of the slots are located between two successive protrusions and separate the protrusions from each other;
- wherein a height of each of the support elements, whose longitudinal axes intersect at the center of the first head part, increases while extending radially from the periphery of the first head part to the center of the first head part, and
- side walls on both sides of each support element and the intermediate walls connecting the side walls of the two successive support elements facing each other form surfaces in which the drive apparatus is engaged to the fastener for tightening and loosening and a torque is transferred to the fastener.
