An expansion anchor includes an anchor bolt with a rear face, a displaceable body located adjacent to the anchor bolt, and at least one wedge body located in a front region of the anchor bolt. The wedge body has a converging zone for displacing the displaceable body. An optically readable code is located at the rear face of the anchor bolt. At least one code protection protrusion projects from the anchor bolt rearwardly beyond the optically readable code.

Provided herein are example aspects of a fire sprinkler assembly and a method for adjusting the height of an adjustable drop. In one aspect, the fire sprinkler assembly can comprise a bracket hub coupled to a bracket bar; a flexible conduit; an adjustable drop coupled to the bracket hub, the adjustable drop defining a lengthwise axis oriented transverse to the bracket bar, and the adjustable drop comprising: an inner casing, wherein the flexible conduit is directly coupled to the inner casing; and an outer casing surrounding the inner casing, the inner and outer casings including corresponding threading to permit rotation between the inner casing and the outer casing to adjust an axial height, along the lengthwise axis, of the inner casing; and a sprinkler head extending from the adjustable drop.

A measuring device for a fastening device includes a base body, a sensor unit configured to detect at least one fastening variable, and an interface connected to the sensor unit and configured to provide the detected at least one fastening variable to an external reading device. The interface is electrically connectable to a wireless communication unit or directly connectable to the external reading device.

Systems, methods, and devices are provided for aligning a reference axis of an accelerometer with a measurement axis of a machinery component. An adaptor including a mounting plate, a plate stud integrated within the mounting plate, and a screw can be coupled to an accelerometer to ensure proper alignment of the reference axis of the accelerometer with the measurement axis of the machinery component. Aligning the reference axis and the measurement axis using the adaptor ensures that the axial orientation of the vibration data collected by the accelerometer properly corresponds to the intended axis of measurement of the machinery component and thus allows for consistent, repeatable installations of the accelerometer onto the machinery component without introducing alignment errors which can generate erroneous vibration data with respect to one or more axes of measurement.

A composite laminate for connection to at least one attachment component in a load-introduction joint, said composite laminate comprising an opening that is adapted to receive a load-introduction component of said load-introduction joint, wherein a prefailure indication element is provided in the region of said opening, said prefailure indication element being modifiable by said load-introduction component in a prefailure mode of said load-introduction joint for indication of an impending function-affecting failure of said composite laminate. The invention is further related to a corresponding load-introduction component.

Method and installation kit for fastening a plurality of individual objects to a supporting structure via blind rivet nuts guided through respective openings in the plurality of individual objects and in the supporting structure, in which an opening in one of the plurality of individual objects and an opening in the supporting structure to be fastened together have different sizes. Each blind rivet nut has a rivet shank and female thread with a same size female thread, and at least two of the blind rivet nuts have different outer sizes. Method includes selecting outer size of one blind rivet nuts according to the size of the opening in the one of the plurality of individual objects and the size of the opening in the supporting structure; screwing a threaded spindle into the female head of the selected blind rivet nut; and forming a closing head by pulling the threaded spindle.

The present disclosure provides a fastening assembly for attachment of a component. The fastening assembly is self-locking, and comprises a housing that presents a barcode, and a retention clip that is configured to form an interlock with the housing and is changeable between an open configuration adapted to freely receive a component, and a closed position adapted to capture and retain the component. The retention clip is slideably moveable within an aperture of the housing between an initial position, in which the retention clip is in the open configuration and the barcode is unreadable, and a final position, in which the retention clip is in the closed configuration and allows for the barcode to be read or scanned to verify installation of the fastening assembly on the component.

A fire sprinkler assembly includes a flexible conduit; and an integral hub and bracket assembly comprising: a bracket hub coupled to a bracket bar; and an adjustable drop integrally formed with the bracket hub, the adjustable drop defining a lengthwise axis oriented transverse to the bracket bar, the flexible conduit coupled to the adjustable drop; and a sprinkler head extending from the adjustable drop.

In one embodiment, an apparatus includes a module for use in installing a heatsink, the module comprising a fastener, a first indicator member comprising a first visual indicator surface, and a second indicator member comprising a second visual indicator surface, the first and second indicator members defining an opening for receiving the fastener. The first visual indicator surface is visible when the fastener is not fully installed and the second visual indicator surface is visible when the fastener is fully installed. A method for installing the heatsink with the module is also disclosed herein.

A coupling includes a male adapter and a female adapter, and may include a nut and a sleeve. In embodiments, the male adapter includes a male adapter inner diameter, and may include threads. A method of operating a fluid coupling may include providing a first member, a second member, a nut, and a sleeve, connecting the sleeve with the nut such that rotation of the sleeve causes rotation of the nut, rotating the sleeve to connect the first member with the second member, engaging an inner ratchet profile of the sleeve with a ratchet profile of a shoulder of the first member, and covering the shoulder of the first member, including the ratchet profile, with the sleeve.
