A tool for installing a blind fastener including a bolt and a nut includes a base, collet, socket assembly, drive body, and mode clutch. The collet is coupled to the base and disposed about an axis. The collet can selectively engage a portion of the nut. The socket assembly includes a socket housing and a plurality of rollers. The socket housing is rotatable relative to the collet and defines a bore disposed about the axis. The rollers are spaced circumferentially about the axis. A surface of each roller can engage a cylindrical portion of the bolt within the bore to rotate the bolt about the axis. The drive body is coupled to the socket housing and configured to rotate the socket housing about the axis relative to the base. The mode clutch is configured to selectively couple the socket housing with the collet for common rotation about the axis.

Push nuts for cars, comprising a head having a member contact surface formed protruding in left and right sides, and having a fastening hole formed penetrating at the center; and a body having formed penetrating at the center, a fastening hole having the same inner diameter and center as the fastening hole which is formed at the head, characterized in that the body and the head are connected to a connecting bridge that elastic deformation is performed outwards, and the head and the body connected with the connecting bridge respectively have a head axial force support and a body axial force support formed protruding toward a space, the head axial force support and the body axial force support having fastening holes having the same center as the fastening holes respectively formed penetrating.

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 tool for installing a blind fastener. The tool includes a retention member and a gripping member that defines a longitudinal axis and is moveable relative to the retention member along the longitudinal axis, the gripping member further defining a receiving cavity that is elongated along the longitudinal axis, an axial opening into the receiving cavity, and a radial opening into the receiving cavity. The tool also includes a contact element at least partially received in the radial opening and a locking collar moveable relative to the gripping member along the longitudinal axis between at least a first position and a second position. In the first position the locking collar engages the contact element and urges at least a portion of the contact element into the receiving cavity. In the second position the locking collar is disengaged from the contact element.

A blind fastener for connecting panels includes a bolt and nut. The bolt includes a shaft, bolt head, and lug. The bolt head is between the shaft and lug. The shaft defines external threads opposite the bolt head. The lug includes a first tool engagement portion and first frangible portion that connects the lug and bolt head. The nut includes a sleeve, nut head, and handling member. A central bore of the sleeve receives the shaft and defines internal threads mated with the external threads. The nut head is between the handling member and sleeve. The nut head extends radially from the sleeve and defines a recess that receives the bolt head. The handling member surrounds a portion of the lug. The handling member includes a second frangible portion and a second tool engagement portion. The second frangible portion couples the second tool engagement portion to the nut head.

Disclosed is a method of manufacturing a deformable sleeve nut that includes selectively strain hardening only a first portion of a material blank while not strain hardening a second portion of the material blank, then, after strain hardening the first portion of the material blank, internally threading the first portion of the material blank to define a nut portion and machining the second portion of the material blank to define a deformable sleeve portion that includes an end portion and a bulbing portion positioned between the end portion and the nut portion, where the bulbing portion is constructed to bulb outwardly and form a load bearing flange when the bulbing portion is compressed between the end portion and the nut portion. Also disclosed is a deformable sleeve nut made with this process.

A nut (32) for assembling elements of a structure comprises a collar (64) capable of coming into contact with a front face of the structure; a tightening zone having an outer diameter (86) capable of being inserted into a hole of the structure; a deformation zone adjacent to the tightening zone and capable of forming a bulge against a rear face of the structure, opposite the front face; and a tapped portion (65) adjacent to the deformation zone. The nut may include grooving (82) on an outer circumference of at least one part of the deformation zone, a maximum diameter of said grooving (82) being less than or equal to the outer diameter (86) of the tightening zone.

A rivet-like fastener assembly adapted to be mounted in a hole through a wall having front and rear surfaces and comprising a body having a head portion and a hollow shank portion extending axially from the head portion and having an internally threaded section and an intermediate section, the head portion having an inner radial section having a first axial thickness between a front head surface and a first portion of a rear head surface and an outer radial section having a second axial thickness between the front head surface and a second portion of the rear head surface, the first axial thickness being greater than the second axial thickness, the first portion of the rear head surface adapted to abut a portion of the wall, and an elastomeric seal adapted to be compressed between the second portion of the rear head surface and the wall.

A fastening means having a blind rivet element and a sealing element, wherein the blind rivet element has a head portion and a shaft adjoining the head portion in an axial direction, wherein the shaft has an internal thread or a connecting portion for a threaded bolt and, between the internal thread or the connecting portion for the threaded bolt and the head portion, a deformation portion for forming a closing head when the deformation portion is deformed. The sealing element has a closed lateral portion and a closed cover portion adjoining the lateral portion in the axial direction, wherein the lateral portion circumferentially encloses the shaft of the blind rivet element at least in the region of the deformation portion, and the cover portion is formed at an end of the shaft of the blind rivet element facing away from the head portion.

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.
