A fastener boss includes a body having a receiving column. The receiving column includes a first section with a first wall thickness and a second section with a second wall thickness wherein the first wall thickness is greater than the second wall thickness. A motor vehicle component incorporating the fastener boss is also disclosed.

A method for fastening a component to a base element, in which method there is produced in the base element a blind bore which defines a depth direction and which has a force transmission surface which has a depth T in the depth direction, wherein the force transmission surface is of frustoconical form with a cone opening half-angle () and a mean diameter (d), wherein the blind bore has a conical blind bore base with a cone opening angle () and, at the edge thereof, a bevel which extends in the depth direction to a bevel depth L, wherein, in the method, a fastening element is anchored in the blind bore by way of the force transmission surface, and wherein the component is held by the fastening element.

A hand-held power tool has a tool socket 2, a drive 5, 6 for driving the tool socket 2, and a housing 19 in which the drive 5, 6 is accommodated. A stationary part 14 of the drive 5 is connected by means of at least one detachable clamped connection 21 to at least one element 19, whereby the element 19 is the housing 19 or another stationary part of the drive 5, 6. The clamped connection 21 has a cylindrical pocket 22 in the one stationary part 14, a bushing 27 that is made of plastic and that is inserted into the cylindrical pocket 22, and it has a screw 30 that is screwed into the bushing 27.

A method of making a cabinet carcass using a pair of connectable box carcass framework members for the fabrication of non-panel constructed furniture carcasses. It simplifies the construction of a furniture carcass and uses but a minimum of tools and skill to produce a dimensionally square, precisely sized, box that accepts an abundance of aesthetic and functional options. The assembly is based on a pair of mechanical fastener connectable vertical and horizontal members that have connectable zipper channels, linear rabbets for the retention of side panels, screw busses, and open channels with series of spaced orifices therein for the passage of mechanical connectors.

The present invention relates to a slidable mounting block for insertion into a rail having a partially closed profile, the mounting block having a front face and a rear face opposite to the front face, the front face facing an open part of the partially closed profile when inserted into the rail. The mounting block comprises a first hole accessible from the front face in a first fixing area of the mounting block and configured for screwing in a threaded part of a first fastener, a recess accessible from the rear face in a second fixing area of the mounting block and configured for holding a head of a second fastener, and a second hole accessible from the front face in the second fixing area, the second hole being co-aligned with the recess and configured for passing a shaft of the second fastener through the mounting block.

A spring retainer includes a locking member which locks one end side of the piston spring, and a rod-shaped member (82) of which one end is in contact with the locking member to restrict a length of the piston spring and the other end is fixed to the piston (11), and the rod-shaped member (82) is installed in a concave portion (140) of the piston (11), and the concave portion (140) has a protruding portion (142), which is extruded by plastic deformation toward a radial direction of the concave portion (140) and is formed of the same member as the opening circumferential edge portion (141), in the vicinity of the opening circumferential edge portion (141).

The present invention relates to fasteners such as screwbolts in general and to anti-shake screwthreaded systems and anti-shake screwthreaded assemblies employing screwbolts in particular. As is universally known, in relation to screws and threaded fasteners, a thread comprise a continuous helical ridge formed on the inside (nut) or outside (screw) of a cylinder. An issue of concern for all types of screw fasteners is that if they rotate relative to a fastened item, they diminish the degree of fastening. Many methods of preventing a relative rotation between bolt and nut have been devised. The present invention seeks to provide an improved screwbolt system for use in engineering and construction. The present invention also seeks to provide a screwbolt for use as a fastener in harsh conditions of load and have a reduced tendency to unfasten. The present invention also seeks to provide a method of installing such screwbolts.

An electric device includes a substrate on which electronic components are mounted, and a metal plate to which the substrate is fixed. The metal plate includes first bosses provided at positions corresponding to four corners of the substrate, a second boss provided inside a rectangle that connects the four first bosses, and a slit that is provided adjacent to the second boss, and extends in non-parallel with any side of the rectangle. The substrate is fixed to each of the four first bosses with a first male screw, such that a rubber washer is sandwiched between the substrate and the first male screw. The substrate is fixed to the second boss with a second male screw, such that no rubber washer is sandwiched between the substrate and the second male screw.

A method for production of an interior unit for a motor vehicle includes production of a support by injection molding, featuring an enclosed front side, wherein at a backside of the support a screw boss is formed whose drill hole is sealed by a support section in the direction of the front side of the support, which support section features a reduced wall thickness in comparison to the remainder of the support, and production of a foam layer on the enclosed front side of the support. Furthermore, the present disclosure relates to an interior unit for a motor vehicle.

The invention relates to a connecting element (1) to connect a battery cell (15) of an electric vehicle (16) to a battery box (10), wherein the connecting element (1) has at least one connecting section (5) for connection to the battery cell and is joined to the battery box (10). The problem addressed by the invention is that of being able at least largely to dispense with the need to use filler material when joining the connecting element to the baseplate of the battery box so as to improve its quality and make it more cost-effective. The problem is solved by a connecting element (1) that has at least one joining section (2) for securely connecting the connecting element to the battery box (10).
