Inexperienced users of conventional self-drilling drywall anchors may apply too much torque to its screw drive, even after the anchor has become fully bedded down in the drywall, under the mistaken impression that applying a greater torque will improve security of the anchor within the drywall. However, continuing to rotate the anchor after it has been fully inserted into the dry wall continues to rotate the anchor within the drywall and gouges out drywall material from around the anchor. Such gouging causes a cavity to form around the anchor, reducing its security within the wall. The present invention provides a self-drilling drywall anchor having a screw drive 16 that comprises a clutch configured to limit an amount of torque transmitted to the shank 5 by a tool engaged with the screw drive 16. In this way, a user may drive the anchor into a drywall, but over-tightening is prevented as the clutch limits the amount of torque transmitted to the shank 5, thereby preventing the external threads 7 on the shank from gouging out drywall material adjacent to the anchor and reducing the anchor's security within the drywall.

A bolt includes a head, and a shank connected to the head and having a screw portion and a leading end portion. The leading end portion of the shank includes a wall portion that defines a hole. The wall portion includes: a deformation portion configured to be plastically deformed by a torque from a fastening tool to be inserted in the hole; and a space forming portion configured to form a space between the space forming portion and the fastening tool. The blot is configured such that a maximum torque applied to the deformation portion in a process, in which a part of the deformation portion is plastically deformed by the torque from the fastening tool and is accommodated in the space and the fastening tool is placed in an idle rotation state, is configured to be set to be within a predetermined range.

The invention relates to a screw element comprising an internal torque limitation for fastening a liquid-conducting line to a device connector or to a coupling for a further line, said screw element having a connection part, which preferably has a thread, and an actuation part; and having a torque limiting unit that limits a torque that can be transmitted from the actuation part to the connection part, wherein the torque limiting unit is arranged between the connection part and the actuation part and has a limiting element, in particular a separate limiting element, that can be assembled from at least two limiting element parts connectable to one another and that limits the torque limiting unit in an axial direction of a longitudinal axis of the screw element. The invention further relates to a system comprising at least one screw element and a line fastened to the screw element.

A jaw member for a support assembly for securing a bicycle to a load carrier for a vehicle. The jaw member includes a frame work structure formed by at least one support element and at least one rib. The frame work structure is adapted to enable the jaw member to withstand a relative high amount of tensile stress while still being relatively light weight.

A pipe clip includes a metal annular clip body having at least two opposing radial flanges defining an opening adapted to arrange the pipe clip around a pipe. The clip body has at one of the radial flanges a female fastening. The pipe clip includes a tightening screw having a head and a shank. The shank is provided with a male thread adapted to cooperate with the female fastening. The head engages the other of the flanges so as to tighten the flanges towards each other and tighten the pipe clip around the pipe. The pipe clip has a vibration insulating lining provided on the inner side of the clip body. A torque limiting cap is arranged on the screw head of the tightening screw. The torque limiting cap includes at least one torque transferring feature that couples the cap to the screw head in a rotational direction.
