A recessed lighting fixture includes an elongated body including a flange and a pair of swing arms. The swing arms are deployable between a stowed configuration adjacent to the elongated body, to a deployed configuration wherein the swing arms extend radially from the elongated body. In the deployed configuration the swing arms are translatable along threaded members extending along the elongated body in order to clamp a ceiling or other surface between the swing arms and the flange to secure the recessed lighting fixture into a hole in the ceiling. The swing arms comprise removable portions that can be used to increase the range of thicknesses of surface in which the recessed lighting fixture can be installed.

A rivet may include a pin comprising: a threaded portion (36), a shank (38) and a head (40); and a bushing (32) comprising an essentially cylindrical body, said body comprising a deformation zone designed to form an external bulge (80); a collar (70) designed to receive the head of the pin; and a tapped portion (66) designed to engage with the threaded portion of the pin. The shank (38) of the pin comprises a first cylindrical portion (44) and a second cylindrical portion (46) connected by a shoulder (48), the first portion being adjacent to the head and having a first diameter, the second portion being adjacent to the threaded portion and having a second, smaller diameter.

A retaining device for securing one or more accessory racks to a base rack on a vehicle is provided herein. The device comprises a housing member that extends through the one or more accessory racks and into the base rack, a head, secured to the housing member that engages one or other of the racks, a detent that engages the other of the racks, and an engagement mechanism that extends the detent and pulls it toward the head. The device may further comprise a lock that secures the detent in a clamping position. The lock may comprise a ratchet and pawl arrangement defined by first and second levered tabs disposed on the head, the first tab being operably connected to the engagement mechanism. An ATV comprising one or more accessory racks secured to a base rack by a retaining device as described herein is also provided.

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 blind tacking rivet includes a stem and a sleeve. The stem includes a body and a stem head. The stem head is removable from the body. The stem head deforms a portion of the sleeve during removal of the stem head. The stem head may be discarded or may be embedded within the sleeve.

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.
