Disclosed is a fixing (1) for securing an article (21) to a surface (19). The fixing comprising a coupling arrangement (3) for coupling the fixing to an article such as cabling. Elongate members (5) extend from the coupling arrangement and are moved together to insert the fixing into a cavity (17), and spring apart to retain the fixing in the cavity. The elongate members have resiliently deformable inner formations (9). The inner formations engage with one another and resiliently deform when the elongate members are brought together, thereby increasing the pull resistance of the fixing. The inner formations are inwardly extending branches each presenting a ramped surface oriented towards the distal ends (8) of the respective elongate member, assisting in coupling an article to the fixing.

Fastener embodiments of the invention comprise a freely translatable collet body, which at least partially translates within an auxiliary structure, and further comprise a captive threaded screw for rotationally engaging with the collet body to transform rotational movement into translational movement through substantial arresting of collet body rotation by way of an anti-rotation means. The screw comprises a free-spin feature that functionally, but not physically, decouples a drive tool from the collet body.

A mounting system includes a body extending from a first end to a second end. The mounting system includes a bracket adjustably coupleable to the first end to secure the body to a wall with a portion of the body between the first and second ends spaced apart from the wall. The first end of the body includes a first projection having a groove configured to receive a key of a second projection of the bracket to rotationally fix the bracket relative to the body.

A device for fastening a first object to a second object in a fastening direction is provided, the device comprising an anchoring element, a tension element and a prestressing element, wherein the anchoring element is provided to be anchored in a fastening direction in the second object, wherein the tension element is provided to transmit a tensile force from the anchoring element to the prestressing element to prestress the prestressing element in the fastening direction against the first object, and wherein the tension element comprises a composite of a plurality of fibers.

A fastener assembly including a fastener body having a collar and a receiving column with a protrusion on an inner surface thereof, and a pin having a threaded section. The protrusion is configured to engage and cooperate with the threaded section.

Provided is an expansion-type anchor with excellent pull-out strength. The anchor comprises an anchor body 1 that has an expansion section 3 split by an inner slit 2, and a sleeve 9 to enclose and hold the expansion section 3 of the anchor body 1. The sleeve 9 is split into a plurality of follower expansion sections by an outer main slit 10 and an outer auxiliary slit 11. A group of balls 4 is disposed inside the anchor body 1, and the expansion section 3 expands into a tapered shape when the group of balls 4 is pressed by an expansion bolt 6. When a pull-out force is applied to the anchor body 1, the sleeve 9 does not retract and deforms by expanding after the retraction of the anchor body 1. As a result, the anchor body 1 is prevented from retracting by way of the sleeve 9 being sandwiched between a prepared hole 13 and the expansion section 3.

A hanger assembly and method of hanging conduits in buildings is described which protects the structure of the building from damage during a seismic event. The hanger assembly includes a frangible element which is calibrated to break when subjected to some higher than normal tensile load resulting from rapid acceleration of the conduit. Thus, for example, in the event of an earthquake, the hanger will fail before damage is done to the concrete to which the anchor is attached.

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.
