Disclosed is a sheet-metal fastener configured to join two components, such as sheet-metal. The sheet-metal fastener comprising a head and a shank. The head may define an undercut region and a serrated region. The serrated region can be positioned at an outer perimeter of the head. The serrated region can be composed of a plurality of knurls. The shank extends perpendicularly from the undercut region and comprises one or more threads.

The invention relates to a support structure for an article. In particular, the invention relates to a support structure for mounting modular articles such as display units and the like upon a wall. The support structure comprises a support bracket (1), the support bracket having at least one opening (15), the opening being sized to accommodate a fixing (4) by which the support bracket may be secured to a wall (3), the opening being larger than the fixing whereby the position of the support bracket (1) may be adjusted relative to the fixing (4). The support structure also comprises a support element (2), the support element having a dimension (d) which is larger than the opening (15), the support element having a fixing hole (14) therethrough, the distance between the fixing hole (14) and the periphery of the support element (2) being non-uniform. The support bracket (1) has a support surface (12) adapted for engagement by the periphery of the support element (2). The invention also provides a method of mounting the support structure, and a support bracket for use in the structure and method.

In a device for releasing a securing screw for a unit in a housing, in particular a pinion unit in a steering gear of a motor vehicle, the securing screw is connected via an external thread to an internal thread in the housing, wherein the securing screw is provided with a latching device, which has latching levers disposed distributed on the circumference of the securing screw, each of which said latching levers is provided with latching lugs disposed on the free ends of the latching levers. The latching lugs latch into teething gaps of a teething geometry of the housing. The latching devices can be connected to a tool in order to release the latching levers having the latching lugs from the latched position by means of a radially inwardly directed movement of the latching levers.

A straight threaded rod has three reference elements spaced apart from each other. A shoulder and a knob having a fourth reference element are screwed onto the rod. A spring is mounted on the rod between the knob and the shoulder. The rod is inserted through two axially aligned holes in two abutting pieces, with the shoulder bearing on a first surface of one of the two pieces. By adjusting the position of the shoulder and the knob along the rod it is possible to apply a calibrated clamping force to a pair of abutting pieces, regardless of the thickness of the pieces.

A set of screws with function of screwdriver each comprises a circular head with a torque slot across the top thereof. The torque slot has two opposite semi-moon shaped sides, a curved bottom, and a width about the same as the height of the circular head. One of the screws acts as the fastener, and another one of the screws acts as the screwdriver by that the circular head of the screwdriver is inserted to the torque slot, and the screw body thereof is perpendicular to the fastener to form an arm for being exerted a force to the fastener.

The latching lugs latch into toothing gaps of a toothing geometry of the housing. The latching device can be connected to a tool in order to release the latching levers having the latching lugs from the latched position by means of a radially inwardly directed movement of the latching levers.

A self-contained tool bolt has a head section comprising a top member and a handle section which is expandable from a stored position to a laterally outward, cantilevered position relative to the top member, to provide enhanced tightening and loosening capability of the tool bolt. The tool bolt also comprises a rigid shaft extending from the top member and a bolt section, with external threads, slideably mounted and moveable along the shaft. When the bolt section is at its lowest point on the shaft, the handle section is elevated to provide clearance from obstructions during tightening and loosening of the tool bolt.

A security mounts includes a shield surrounding a socket head screw. The shield has a hole in it that generally aligns with the socket portion of the socket head screw. The perimeter of the shield hole has a geometric shape that corresponds to the geometric shape of the cross section of the shank of a wrench used to turn the socket head screw. An unconventional tool has a reduced cross section portion of the shank that is able to rotate around in the shield hole.
