A fastener for a corrugated sheet includes a cylindrical assembly including elongated, plate shaped fastening members assembled as a hollow cylinder. Each fastening member is tapered to one end to form a hook at one end and having a curved groove on an outer surface, and a curved trough on the outer surface at the other end of the fastening member. The curved troughs are assembled to form an annular recess. A retainer ring is secured to the annular recess. A ring-shaped elastic member is secured to the curved groove. A first sealing member is put on the retainer ring. A threaded bolt driven through a washer, the retainer ring, and the fastening member. An expansion nut has a multi-sided outer surface and is moveably secured to the threaded bolt.

Embodiments of the disclosure relate to an apparatus that disengages a tool and indicates undesired contact. More specifically, the embodiments of the disclosure relate to a fastener that limits over insertion, indicates over insertion, and limits undesired contact of that fastener with a surface. Further, the apparatus can limit damage to an underlying component such as a circuit board. The apparatus has a shank having a cavity extending through the shank. Additionally, the shank has a recess for installation by a tool. A slider is positioned within the shank wherein the slider can limit engagement with the recess and indicate a condition.

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 mechanical fastening device is provided. The device comprises two principal components: a stud and a corresponding nut. The stud is engineered with a central longitudinal axis, a threaded section for robust engagement, and a handle section to enable manual manipulation without auxiliary tools. The nut component is outfitted with a manually operable knob, a rod section that incorporates a hollow interior to accommodate the stud, and an access opening positioned opposite the knob for straightforward insertion of the stud. Additionally, a strategically designed curved transition area between the rod section and the knob enhances the structural integrity of the nut and reduces the potential for snagging or injury during use. This invention is optimally suited for diverse applications that demand reliable and user-friendly fastening mechanisms.

A method is provided for producing a composite fiber component with an integrated screw-in insert. A pressing tool is provided. The pressing tool has a first tool part and a second tool part that can be moved in relation to the first tool part. The parts form a cavity for receiving and forming a fiber preform, when the pressing tool is closed. A screw-in insert is connected to a screw device integrated into the first tool part. The fiber preform is arranged between the first and the second tool parts. The pressing tool is at least partially closed. The screw device is actuated in order to screw the screw-in insert into the fiber preform. The fiber preform is cured.
