In one aspect the invention provides a nut and tie rod assembly which includes a composite material tie rod defining a main shaft with an exterior surface. The tie rod is formed from reinforcing fibers encapsulated within a matrix material, and at least a portion of the exterior surface of the shaft defines an engagement structure. The assembly also includes at least one nut which includes an internal cavity with an interior surface defining an engagement structure which is complimentary to the engagement structure defined on the exterior surface of the shaft of the tie rod.

The present disclosure relates generally to utensil holders, and more particularly, the present disclosure relates to such holders that are flat card-like all-in-one tool and holder. The present disclosure provides a robust, durable, waterproof flat all-in-one tool and holder having not only compartments for a number of removable or deployable tools such as but not limited to a Phillips Power/Driving Bits, Hex Power/Driving Bits, Torx Power/Driving Bits, Slotted Power/Driving Bits, and Flathead Power/Driving Bits or the like, but also one or more edges is carved to have at least a box cutter, a string cutter, a bottle opener, a wingnut tool, a plurality of metric wrench set of different sizes, a paint can opener, a threaded locking screw, a wire striper, a plurality of Spoke wrenches (SW) of different sizes, and Swiss T-20 Torn nipple wrench and a Hex Bits socket, and at least a file tool.

An assembly with an aircraft fuel tank is disclosed having a captive nut with an internal thread, a secondary structure, and a fastener which secures the secondary structure to the fuel tank. The fastener has a shaft which passes through the secondary structure and has an external thread coupled to the internal thread of the captive nut. The fuel tank has a fuel tank element with a hole, and the captive nut has a sleeve which is located in the hole with an interference fit between an outer surface of the sleeve and an inner surface of the wall of the hole.

A positioning device with tolerance compensation including: a screw; a primary tightening member, and a secondary nut. The screw includes a driving portion cooperating with a driving tool to rotatably drive the screw and is located in an axial end portion of the screw; primary and secondary external threads, the primary external thread being further from the driving portion than the secondary external thread, the directions of the secondary external thread and the primary external thread are opposing; and an abutment projecting between the primary and secondary external threads. The primary tightening member includes a primary internal thread adapted to cooperate with the primary external thread, the primary tightening member and the abutment secured to an intermediate component. The secondary nut includes a secondary internal thread cooperating with the secondary external thread and is configured to bear against the intermediate component to fasten a first component on a second component.

A tamper-proof screw includes a main body, a pin body, a ball, and at least one abutting member. A through hole is provided in the main body. The pin body is movably disposed in the through hole. The ball is located in the through hole. The abutting member is located in the through hole and has a connecting end and a free end opposite to each other. The connecting end is disposed on an inner wall of the main body and located between the ball and the free end. The ball is located between the pin body and the abutting member. When the pin body moves in the through hole to push the ball to press against the connecting end of the abutting member, the abutting member pivots around the connecting end to allow the free end to extend outwards from the main body.

A shear bolt for a junction of electrical conductors includes a tool seat for engagement of the shear bolt by a screwing tool, an externally threaded portion to be screwed in a terminal body of the junction, along a screwing axis, and a tightening portion for engaging an electrical conductor to be tightened in the terminal body. The tool seat is formed at the threaded portion and the tightening portion is connected to the threaded portion on an opposite side with respect to the tool seat. The shear bolt can be sheared in one or more programmed rupture areas in the threaded portion when exceeding a predetermined tightening torque for each of the programmed rupture areas, respectively. Even with the screw unscrewed, the tightening portion is connected to the threaded portion and is rotatable with respect to the threaded portion about the screwing axis and non-detachable from the threaded portion.

A fixture connection assembly includes separate connection and threaded stem components. The threaded stem component includes both threaded and non-threaded portions, where the threaded stem may be re-sized and still produce useful fitted stems from discarded portions.

The invention relates to a method for producing a threaded bolt. A blank is introduced into a threaded-bolt negative mold. The blank has a bolt-shaped portion. Fibers which are aligned in the longitudinal direction of the bolt-shaped portion are embedded in a plastics material in the blank. Pressure is exerted on the blank in order to deform the blank in the negative mold such that a threaded structure is formed on a circumferential face of the bolt-shaped portion. The invention moreover relates to a threaded bolt which is manufacturable by this method, and to a system which is conceived for carrying out the method. Lightweight and hard-wearing threaded bolts may be manufactured by the method according to the invention.

A fastening system for attaching a cover to an underground vault having a bolt with threads and a composite fiber reinforced polymer nut having a thread engagement portion extending through the nut which will fail in shear after the bolt is inserted before the nut and bolt seize. The fastening system can also include a nut retainer sized to allow the nut to float within the retainer.
