A blind fastener device for fastening at least two workpieces, including a sleeve, an expander having a tensioning section, a locking section, and an expansion section, and a nut. A portion of the expander passes through the sleeve to cooperate with the nut so that relative rotation of the expander and nut draws the expander's distal end toward the sleeve's proximal end thereby drawing a portion of the expansion section of the expander into a structural region located on the sleeve and expanding at least a portion of the sleeve's structural region, and drawing a portion of the locking section past the sleeve's distal end toward the sleeve's proximal end and deforming at least a portion of the sleeve's distal end to a locked state. The sleeve may be configured as a multi-section sleeve having a sleeve retainer to locate the sections in a predetermined relationship.

CONSTRUCTIVE ARRANGEMENT IN A COMPONENT FOR BRACKETING AND FASTENING OF PROFILE HANDLE, which bracket (1) to be fastened by screw on the top edge (T) of the front wall of the door or drawer (A) of the furniture, and provided with side recesses (3) which configure rails for fitting and sliding of the corresponding tines (4) existing in the inner region in the base of the profile type handle (P), and said bracket (1) is shaped rectangularly, elongated, with the fastening hole (2) positioned in its internal end and opposite to the end where one of the positioning tabs (5) is provided, and at the ends of the side recesses (3) are provided with directing ramps (7) for the introduction and fitting of the tine (4) of the profile (P), while the fastening hole (2) is provided with vertical fins (8) that configure anchoring elements of the fastening screw.

A fastener for securing drywall to a framing member includes an elastomeric sleeve that reduces the transmission of sound through the drywall to the framing member and vice versa.

A fastener including a bolt having a head, a shank portion, and an annular groove located intermediate the head and the shank portion, and a sleeve having a head, a shank portion, an inner cavity, a recess located in the head of the sleeve, and an annular tab located at a bottom of the recess and proximate to the shank portion of the sleeve. The sleeve receives the bolt such that the shank portion of the bolt is positioned within the inner cavity of the sleeve and the head of the bolt is positioned within the recess of the head of the sleeve. When the bolt is in an installed positon within the sleeve, the annular tab of the sleeve is deformed and engages the annular groove of the bolt.

A fastener including a body having a threaded portion and an opposing, tapered portion, where the tapered portion includes an outwardly angled surface, and a sleeve movably connected to the body. The sleeve includes a plurality of fingers at least partially separated from each other, where each of the fingers includes at least two, axially spaced gripping members protruding from the body. When the fastener is inserted in a borehole formed in a substrate and a fastening member is threaded onto the threaded portion and tightened, the sleeve progressively moves along the angled surface causing the fingers to move outwardly and at least one of the gripping members to engage an inner surface of the substrate forming the borehole to secure the fastener in the borehole.

An expansion anchor includes a screw and an anchor body configured to receive a shank of the screw, the anchor body including: a flange configured to be directed towards the screw head; a nut-forming portion configured to cooperate with the screw thread; and a deformable expansion portion between the flange and the nut-forming portion. The nut-forming portion is configured to advance in the direction of the flange, by deforming the expansion portion to a deployed state, by screwing the screw in the nut-forming portion. When the anchor is mounted inside a hole in a wall, with the flange bearing against a first face of the wall, the expansion portion in the deployed state forms a continuous contact surface facing a second face of the wall and has a load-bearing section, transversely with respect to the screw axis, which is generally decreasing from the contact surface towards the nut-forming portion.
