An object of the invention is to resolve the inconvenience of separately handling a nut member and a bolt member and improve workability in fastening and fixing a part. There is adopted a part fitted with a fastening member including: one fastening member that includes a high-rigidity screw portion, a low-rigidity crushable portion, and a locking portion provided against a member to which a part is attached; another fastening member that includes a screw portion tightly screwed with the high-rigidity screw portion to be able to crush the crushable portion; and a part that is temporarily fastened and held between the one fastening member and the other fastening member while the two screw portions are loosely screwed together.

The invention relates to a fastening element (10) for connecting to a component (12), wherein the fastening element (10) comprises a flange with drive structures, wherein a connection region is formed on the flange, through the fusing of which the fastening element (10) can be fastened to the component (12) by friction welding, wherein the fastening element (10) comprise a shaft which is arranged on the side of the flange opposite the connection region. The fastening element (10) further comprises a guide region between shaft and connection region in the axial direction, which comprises a guide surface, which comprises at least one segment of an outer surface, which is associated with a cone which broadens in the direction of the connection region. The invention is characterized in that the guide region has a flat surface on the end thereof facing towards the shaft, wherein the extension of the flat surface in a radial direction is greater than the diameter of the shaft.

A Blind nut may be mounted on a hole of a mounted member. The blind nut includes a main body with a plastically deformable material and a nut member with a relatively harder material. The main body has a cylindrical first tubular portion and a second hexagonal and cylindrical tubular portion provided adjacent to first tubular member. A flange is provided adjacent the second tubular member. Nut member includes a short cylindrical nut base member. Nut tubular members are adjacent nut base member and have a smaller outer diameter than that of the nut base member. A female threaded pass-through hole extends across the length of the nut member. The nut cylinder members are inside the first tubular member and the second tubular member; and the lower edge of the main body tubular member is in contact with a step member of the nut base member and welded thereto.

A blind nut assembly including a bush and nut. The bush includes a short cylindrical collar, which has a polygonal outer surface on the outer surface thereof, and a flange, the outer surface of which is polygonal. The nut consists of a female screw member, on which a female screw to be mated with a male screw on a bolt is formed; and a nut cylindrical member, which is formed adjacent to the female screw member, which has a polygonal inner surface on the inner surface thereof aligning with the polygonal outer surface of the collar, of which the outer surface is also a polygonal outer surface, and which has a wall thickness that is thinner than the female screw member. The nut head has an outer diameter which is larger than the maximum outer diameter of the nut cylindrical member, is formed above the nut cylindrical member.

A deep-drawn, marine hull having a sandwich structure and watercraft utilizing same are provided. The hull includes an outer skin having a waterproof outer surface, an inner skin having a compartment-defining outer surface and a shock absorbing, cellular core positioned between the skins. The skins are bonded to the core by press molding. The cellular core has a 2-D array of cells, each of the cells having an axis substantially perpendicular to the outer surfaces. Thickness of side walls of the hull is substantially uniform to maximize stiffness of the hull. The cells absorb energy of an impact at the outer surface of the outer skin by deformably crushing. Air trapped within cells which are not completely crushed or punctured by the impact provide the hull with buoyancy to allow the hull to float at the surface of a body of water.

An adjusting element formed in one piece and made of metal for compensating a tolerance in the distance between a first and a second component is described. The adjusting element comprises: a hollow-cylindrical body having a radially outwardly extending flange adjacent to a first axial end and an outer thread of a first thread direction at a radial outer side, a drive feature so that the adjusting element is rotatable by a tool, a receiving portion at the radial inner side of the hollow-cylindrical body, in which a dragging element is to be received, wherein the receiving portion comprises at least one radially inwardly extending protrusion, in particular a plurality of radially inwardly extending protrusions, at a radial inner side of the hollow-cylindrical body adapted to a form-fit connection with the dragging element and at least one shoulder extending circumferentially at the radial inner side and providing an axial limitation.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.

A method comprising threading a blind rivet nut onto an output shaft of the tool, pressing the blind rivet nut against a workpiece, thereby applying an external force to the output shaft to move the output shaft in a rearward direction along a longitudinal axis from a first position to a second position, activating a first motor to rotate the output shaft about the longitudinal axis in response to the output shaft reaching the second position, thereby further threading the blind rivet nut onto the output shaft, and activating a second motor to translate the output shaft along the longitudinal axis in the rearward direction, thereby setting the blind rivet nut on the workpiece.

A rivet nut has a through-hole and a target member is assembled with the rivet nut passing therethrough. The rivet nut includes a cylindrical body, a protrusion formed on and protruding from a lower end of the cylindrical body, and a flange formed on and protruding from an upper end of the cylindrical body. The target member is assembled by the flange contacting an upper-end surface of the target member and the protrusion contacting a lower-end surface of the target member.

A contact device for establishing an electrical connection to a contact point of a printed circuit board is insertable into a contact hole arranged at the contact point, so as to establish an electrical connection to the contact point of the printed circuit board. The contact device includes a contact element having a deformation portion and a screw element operable to be screwed into the contact element. The deformation portion is in a longitudinal extension state when in a pre-assembly state and is operable to be deformed out of the longitudinal extension state when in an assembled state by means of the screw element being screwed at least part way into the contact element.
