  • Publication number: 20190032699
    Abstract: A securing element includes a threaded region, wherein a securing rotational direction and an axial clamping direction are defined by the thread design. The securing element has a head with a head lower face which faces the clamping direction and via which a force-fitting connection with a component can be produced. The head is designed such that the head lower face has an edge region at a radial distance from the head center, and the contour of the head lower face runs opposite the clamping direction in the direction of the head center starting from the edge region, whereby a spring effect can be produced. The edge region has a changing circumferential level in the axial direction. Opposite the securing rotational direction, the circumferential level rises at a rising angle of maximally 15° in the clamping direction over a central angle of at least 65°.

  • Patent number: 10160068
    Abstract: A method for supplying, positioning and processing fixing elements using a transport means which moves the fixing elements from a starting position to a processing position whereby the individual fixing elements are introduced into a chuck provided with two clamping jaws, are held by the clamping jaws in an engaging position and, once the chuck has been positioned, are taken up from this position by a driving element and the chuck presses them against a locating device and a connection is made to a component part by the driving element when the chuck is opened, wherein the upward motion of the chuck, while feeding the fixing element to the locating device, prevents the supply of further fixing elements to the chuck.
