The present disclosure discloses a fastener assembly. The assembly comprises a stud having a head portion connectable to an actuator, and a shank extending from the head portion. At least a portion of the shank comprises threads, and an insulating material extends on the threads. A resistor module comprising one or more resistors is configured on the insulating material. One end of the one or more resistors is connectable to a power source, and other end of the one or more resistors is connectable to the power source through a nut engageable with the threads. A movement of the stud relative to the nut varies net resistance across the resistor module. The variation of net resistance across the resistor module may be used to determine position of the nut relative to the stud.

A fastener is disclosed. The fastener can be used to couple together two or more parts in an electronic device. The fastener may include a head coupled with a platform having a shaft extending from the platform. The head is coupled with the platform in a manner that allows the head to decouple from the platform. For example, the head is secured with the platform by an adhesive that provides an adhesive bonding force. In this regard, a rotational force applied to the head that is greater than the adhesive bonding force causes the head to decouple from the platform. The shaft may include several blades and several protrusions. The blades may be used to engage one of the parts. The protrusions may also engage the same part as the blades, and interlock with the part to provide a retaining force that prevents the fastener from decoupling from the parts.

A safety shear bolt includes a main bolt portion and a torque head portion connected to the main bolt portion. The torque head portion includes an extended head portion, a stem portion rigidly connecting the main bolt portion to the torque head portion, and a coupling mechanism rotatably connecting the extended head portion to the main bolt portion. The stem portion is configured to shear when a predetermined torque is applied to the extended head portion, while the coupling mechanism prevents the extended head portion from dropping after shearing off from the main bolt portion.

A system for preloading tension in a stud using an anti-seizure spacer for tapered thread connections is provided. The system comprises a hydraulic tensioning device including a nut configured for threadably engaging the stud, a foot, a cylinder having a first bore defined therein and a surface for engaging the foot, and a piston movably positioned within the first bore, wherein a hydraulic cavity is defined therebetween. The device further includes a puller screw including male tapered threads configured for being threadably coupled with female tapered threads on the stud. The puller screw includes a head configured for engaging a surface of the piston. The system also includes a spacer positioned between the male tapered threads of the puller screw and the female tapered threads of the stud. A method for preloading tension in a stud using the spacer is also provided.

An anchor fastener includes a head, a generally cylindrical shaft extending from the head, and a base at a distal end of the shaft. The shaft includes a helical thread on an outer surface and a self-drilling tip at its distal end adjacent the base. The base is frangibly connected to the distal end of the shaft by at least one web of frangible material separable from at least one of the base and the shaft under application of a force to the shaft.

A frangible detent pin comprising a base a pin head and an elastic member. The base is configured to be secured within a bore. The pin head and the base are interconnected through a frangible connection. The elastic member is configured to bias the pin head away from the base. The frangible detent pin has a rigid stage in which the pin head is rigidly positioned relative to the base and a spring-loaded stage in which the pin head is moveable relative to the base under a compression load between pin head and the base. The frangible detent pin is configured to transition from the rigid stage to the spring-loaded stage in response to the compression load exceeding a predetermined threshold sufficient to cause the frangible connection to fail.
