  • Expansion anchor having a high-strength expansion sleeve in certain areas
    Patent number: 10018213
    Abstract: An expansion anchor is provided having a stud and at least one expansion sleeve that surrounds the stud, whereby, on the stud, there is an expansion cone that radially widens the expansion sleeve when the expansion cone is pulled into the expansion sleeve. It is provided that the expansion sleeve has a hardness of more than 350 HV in the area of its front end facing the expansion cone, whereby the hardness of the expansion sleeve decreases towards its rear end. A production method for such an expansion anchor is also provided.
    Type: Grant

  • Handheld power tool
    Patent number: 9970467
    Abstract: An expansion anchor including a bolt and an expansion sleeve surrounding the bolt is provided, the bolt having: an expansion cone in the region of the front end of the bolt, which expansion cone radially enlarges the expansion sleeve when moved into same; a threaded section for introducing tensile forces into the bolt; a shoulder that limits a movement of the expansion sleeve away from the expansion cone; and at least one anti-rotation protrusion for inhibiting a rotation of the expansion sleeve in relation to the bolt, the protrusion originating at the shoulder and protruding radially outwards on the bolt. The axial length of the anti-rotation protrusion is smaller than the pitch of the threaded section arranged on the bolt.
