An adapter for a cable hanger includes: a housing having a floor, a vertical wall extending generally perpendicularly from the floor, and side walls extending generally perpendicularly from the floor and vertical wall, each of the side walls including a finger extending generally parallel to the floor, the fingers including first engagement features, the vertical wall including a mounting hole; and a plunger having a main panel and second engagement features on opposite sides of the main panel, the second engagement features configured to engage the first engagement features to restrict relative movement of the plunger relative to the housing.

A fastener structure includes a head, a fastening portion and a twist break portion. The twist break portion is fastened at an object by the fastening portion, or is fastened at another object through the object by the fastening portion. Once the fastening portion is fastened, the twist break portion is twisted and broken. Thus, the fastener structure of the present disclosure is capable of providing a required object with a stable combining effect.

A screw having stacked screw heads includes a screw shank portion with a thread and a screw head portion rigidly connected to each other. The screw head portion is driven to bring the screw shank portion to rotate. The screw head portion includes a first screw head and a second screw head. The first screw head has a first shaped groove on its top plane to receive an operating torque. A neck portion is connected to a bottom plane of the first screw head and a top plane of the second screw head. The second screw head has a second shaped groove on its top plane. The neck portion or the connection between the neck portion and the first screw head or the second screw head has lower torsional endurance than each of the first screw head and the second screw head.

A fastener including a pin member having a shank portion, a threaded portion having a thread, a lock portion having at least one lock groove, and a pull portion located having at least one pull groove. The threaded portion is adapted to be engaged threadedly with a threaded hole of a workpiece to install the pin member therein. The fastener includes a swage collar adapted to be installed into the at least one lock groove of the lock portion to secure a plurality of workpieces. The pull portion is adapted to break off when the fastener is installed.

A mating assembly is provided and includes a first mating component, a second mating component, a bolt to bolt first and second mating components together and an alignment pin. The alignment pin aligns the first and second mating components so that the first and second mating components can be bolted together. The alignment pin is configured to yield upon an application of a specified load thereto. A magnitude of the specified load is less than magnitudes of loads expected to be transferred between the first and second mating components through the bolt once bolting is complete.

A disassembly method for an anchor that is anchored in a hole and that has an anchor bolt is provided, whereby, during the disassembly procedure, a torque is applied to the bolt of the anchor that is anchored in the hole and, in this process, the anchor bolt is stressed until it breaks. An anchor which has a head and whose bolt has an engaging profile so that a torque can be applied to the anchor bolt is also provided.

Disclosed is a fastener assembly comprising at least one of a bolt member and a nut member; and a drive element adapted for engagement by an installation/driving tool, said drive element comprising a body. The body of the drive element is joined either to the bolt member or to the nut member by means of an interposed interlayer structure, the interlayer structure being adapted to fracture in torsional shear and/or tensile stress in response to a relative rotational and/or tensile force applied to the drive element with the installation/driving tool.

A load sensing assembly for a spinal implant includes a set screw having a central opening that extends from a first end of the set screw toward a second end of the set screw. The second end of the set screw is configured to engage with an anchoring member. The load sensing assembly includes an antenna, an integrated circuit in communication with the antenna, where the integrated circuit is positioned within the central opening of the set screw, and a strain gauge in connection with the integrated circuit. The strain gauge is located within the central opening of the set screw in proximity to the second end of the set screw.

A beam clamp for attachment to a flange of a structural building member and from which to support or brace a service component. The beam clamp has a clamp body, and a set screw. The clamp body includes a first jaw section with at least one mounting through hole, a second jaw section, a joining section that interconnects the first and second jaw sections, and a transverse opening that is to receive the flange. A contact surface on the second jaw section is formed with surface irregularities providing a roughness that enhances engagement of the contact surface with the flange. In use of the beam clamp, the contact surface is in contact with the flange of the structural member, the set screw is installed in the mounting through hole, and the flange is secured within transverse opening between the tip of the set screw and the contact surface.

Range taking shear bolts and bolt installation (drive) tools are described herein, which are configured for use with a variety of range taking connectors and conductors.
