A fastening device for fastening add-on parts on carrier components has a plug-in locking device, for locking to a carrier component, and a releasable rotary locking device, spaced apart axially from the plug-in locking device and intended for locking to an add-on part. The rotary locking device has an axial supporting element and at least one locking wing, spaced apart axially from the supporting element and extending away radially from a shank of the fastening device. The supporting element and the at least one locking wing have axial locking surfaces, located axially opposite one another. The axial locking surface of the supporting element is arranged axially between the locking wing and the plug-in locking device. The rotary locking device also has a rotary locking stop, which delimits the rotating-in and/or rotating-out action.

Fastening device

A closing plug for closing holes in objects, in particular for closing holes in vehicle bodies, wherein the closing plug has at least one first circumferential wall which encloses a cavity, wherein a transverse wall is present in the cavity between the circumferential side wall, which transverse wall has an outer shape which corresponds to the shape of the cavity and is attached to the side wall in a circumferential manner, wherein, for the purpose of reinforcing the circumferential wall against yielding outward or inward, at least one reinforcement rib extends transversely through the cavity and so as to connect opposite regions of the circumferential side wall.

Sealing plug

A car body () includes a nut plate () predominantly made of hardened steel, wherein the hardened steel of the nut plate () is welded directly to the car body (). A nut plate () as for use in direct welding to a car body () is also provided. A method for mounting a nut plate (), which is predominantly made of hardened steel, to a car body (), wherein the method involves welding the hardened steel of the nut plate () to the car body ().

Weldable nut plate

Connector, wherein the connector is configured for connecting a first component to a second component, wherein the components each have an opening with cross sections different from a circular cross section, wherein the connector has a cage part which has a radial flange at one end and which has a stem portion with a cross section different from a circular cross section, said stem portion being insertable into the opening of the second component such that the flange is positioned against the front side of the second component, wherein the connector has a nut part which is at least partially accommodated by the cage part and that is rotatable, has an axial opening and has opposite wing portions.

Connector with simplified and reliable mounting

A connector () for fastening a first component () to a second component () of a motor vehicle, includes a bearing collar () for bearing against the first component (), a crossbar () having one or more upper bearing surfaces () for bearing against the second component () and for bracing the second component () against the first component () in a rotated final assembly position, a shaft portion () for passing through corresponding apertures () in the components (), and fastening means () for fastening the connector () to the first component () in a preassembly position. A rotation-blocking device () is configured to block rotation of the connector () in relation to the first component () in the preassembly position and only to release said rotation when the connector () has moved from the preassembly position in the direction of the final assembly position.
