A torque-limiting fastener and a method of assembling the same includes a drive shell, a driven fastener carried by the drive shell, and a clutch axially between the fastener and the drive shell. The drive shell may have a shell base wall including drive-off surfaces, drive-on surfaces, and a shell skirt extending axially away from the shell base wall. The driven fastener may have a fastener base wall including driven-on surfaces, driven-off surfaces, drive tang pockets between the driven-on and driven-off surfaces, and driven-on beam pockets, and a radially outer wall extending in an axial direction away from the fastener base wall. The clutch may have a plate, a driven beam, and a driven tang, wherein the driven beam and the drive tang are cantilevered with respect to the plate. A drive shell, driven fastener, and clutch are individually disclosed.

An example fitting includes: a fitting body having counterbore, where the counterbore defines an annular shoulder within tire fitting body: a spring having a first end interfacing with the annular shoulder of the counterbore; and a seal carrier having: (i) a first end face interfacing with a second end of the spring, (ii) a second end face configured to interface with an internal surface of a port, such that the spring is configured to apply a biasing force on the seal carrier toward the internal surface of the port, (iii) a first annular groove on an exterior peripheral surface of the seal carrier, where the first annular groove is configured to have a radial seal disposed therein, and (iv) a second annular groove in the second end face, where the second annular groove is configured to have a face seal disposed therein.

A ratchet fitting includes a screw portion and an operating portion. One of the screw portion and the operating portion has an engaging member, and the other one of the screw portion and the operating portion has an elastic member and a holding member formed separately from the elastic member. The elastic member and the engaging member are fitted such that a rotational force is transmittable to each other due to engagement of the projection and the protrusion and engagement between the projection and the protrusion is releasable due to deformation of the elastic member. The elastic member has a first fitting portion, the holding member has a second fitting portion, and the holding member and the elastic member are fitted such that the first fitting portion and the second fitting portion are fitted to each other in a rotation direction.

A composite tubular structure includes an elongate composite member having an inwardly tapered section at an end and an embedded nut retained in the end inwardly tapered section for forming a connection with another component. The inwardly tapered section has an inner surface which follows a tapered outer surface of the embedded nut, the inwardly tapered section narrowing the composite member in a longitudinal direction towards the end so as to provide a constriction which retains the embedded nut within the inwardly tapered section. The embedded nut comprises a multipart nut, comprising an internal nut and an internal support member, and wherein the internal nut is arranged to slide within the internal support member in a direction away from the end of, and into, the elongate composite member when the composite tubular structure is under conditions of excessive axial compressive load.

A fluid control assembly includes a body having a female threaded end port, and an end adapter including a male threaded end screw threadably assembled with the female threaded end port, an end connector, and an internal passage extending from the end connector to the end screw. One of the body and the end adapter includes at least one outer peripheral recess, and the other of the body and the end adapter includes a peripheral flange. A portion of the peripheral flange in circumferential alignment with the at least one recess is deformed into interlocking engagement with the at least one recess to rotationally secure the end adapter with respect to the body.

A cable connector attachment is provided, the attachment including at least a hose fitting, wherein said hose fitting is swedged into an associated cable and threaded into a CCP; and a set screw, wherein said set screw is inserted into the hose fitting to ensure the CCP cannot vibrate loose. Optimally the set screw is a tapered screw, so that greater force is applied to the terminus end. A braided hose is disposed in mechanical communication with a stainless hose fitting and secured using one or more fasteners. The hose is securely pressed completely inside the stainless hose fitting and then crimped, and a status signal is optimally provided by a crimp machine when a predefined crimp has been completed, thereby notifying the operator of such status. Optimally the crimp measures between about 1.1-about 1.2 inches.

In the case of a hose connector assembly (1) it is provided for a retaining plate (15) to be used for axially fixing at least two hoses (6, 7, 8) in corresponding hose receptacles (3, 4, 5). The hoses (6, 7, 8) are insertable into respective recesses (16, 17, 18) of the retaining plate (15) by way of a lateral insertion movement (19), and the hoses (6, 7, 8) engage behind the recesses (16, 17, 18).
