A driver for inserting and removing flexible and non-flexible fastening devices. The driver has an attachment for interfacing with the proximal end of the device and a flexible driver rod for interfacing with the distal end of the device. Alternatively, the flexible driver rod can interface with both the distal and proximal ends of the fastening device. The driver further interfaces with a guide wire or other means that connect with the interior of the device.

A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert.

A fluid end having its fluid flow bores sealed without threading a retaining nut into the walls of each bore. The fluid ends may be assembled using a plurality of different kits that each comprise a fluid end body, a component, a retainer element, and a fastening system. The retainer element holds the component within each of the bores formed in the fluid end body and the fastening system secures the retainer element to the body. The fastening system comprises a plurality of externally threaded studs, washers and nuts in some embodiments. In other embodiments, the fastening system comprises a plurality of screws.

A fastener (20) includes a head (22), a base (26), a shearable section (24), and a removable blocking insert (50). The head (22) has an inner surface (30) that includes a first socket (36) for receiving a drive tool (T). The base (26) includes an outer surface (38) having a base thread (44). The shearable section (24) is positioned between the head (22) and the base (26) and has a predetermined torque limit. The removable blocking insert (50) is positioned to hinder access of a drive tool (T) to the base (26).

The invention relates to an accessory for securing points darrt on fencing pes, comprising a screw for securing the point darrt which is located on the tip of a fencing pe, in order to close the circuit of the electric touch-detection device with which said swords are equipped. The invention includes a screw-coupling tool, characterised in that the screw includes a central axially-extending through-hole having a hexagonal or any other prism-shaped configuration, while the actuation end of the tool includes a first cylindrical or frustoconical segment so that it can be easily fitted to the hole in the screw. In addition, a collar is provided half-way along the length or height of the screw, which serves as an end-stop element.

Systems and methods for mounting surgical lighting to the ceiling of an operating theater can include an anchoring tube having attachment holes, and a surgical lighting suspension having internal attachment threads for receiving screws. The receiving screws may be pressure screws. The pressure screws may include a threaded body, and a tightening head which has a smaller diameter than the threaded body. The pressure screws can support and secure the surgical lighting suspension by copressive stress. Anti-loosening screws may be used to secure the pressure screws in place.

A bracket for hanging an item on a wall is disclosed. The bracket has one or more bracket apertures which are used to mount the bracket to the hanging item. The hanging item could be an item like a picture or a shelf. The bracket has a mounting aperture which is used to mount the hanging item on a nail or a screw. Adjacent to the mounting aperture is a pinhole having a set screw. To use the bracket the user unthreads the set screw from the pinhole opening. The user places the hanging item in its desired location on the wall and pushes the item against the wall so that the set screw marks a spot on the wall where the user should place a nail or a screw for hanging the item.

A fastening assembly having a component flange (10), in particular of a turbomachine, having at least one bore (11) in which a sleeve (30) is placed that extends through a bolt (20) which has a head (21) that is axially secured between a rim (12) of the bore and a component flange-mounted axial limit stop (13).
