Abstract: A pipe joint contains a body having a fluid passage in the interior thereof, a tightening cap screw-engaged with an end of the body for connecting a tube thereto, and an indicator ring interposed between a stopper of the body and an end of the tightening cap. The indicator ring is equipped with a flat section and an inclined section, which is inclined with respect to the flat section, and is formed with a smaller diameter than an outer circumferential surface of the tightening cap. When the tightening cap is screw-rotated to thereby connect the tube, as a result of the inclined section being pressed and deformed by movement of the tightening cap, the inclined section projects radially outward with respect to the outer circumferential surface of the tightening cap, whereby a tightened condition is visually confirmed by the outer edge of the indicator ring.

A biasing member is disposed between the keeper and the body member on the threaded fastener to bias the keeper in a direction away from the body member.

Abstract: A self-locking connector system has a connector member having an external thread and an axially extending keyway, and a connecting interface at a distal end. A connector body has a distal end with a connecting interface that mates with the connecting interface of the connector member. An internally threaded nut is captive on the distal end of the connector body encircling the connecting interface and is configured to screw onto the externally threaded connector member. A locking collar is dimensioned to encircle the externally threaded connector member, has at least one key dimensioned to engage in the keyway, and is movable axially on the nut between a first position in which the nut is rotatable relative to the collar and a second position in which the nut is not rotatable relative to the collar.

Abstract: A nut lock includes a nut body, a locking coil, and a cage. The locking coil includes first and second tangs and has an internal diameter that is smaller than the internal diameter of the nut body. The cage is fixed within the nut body and includes a circumferential wall defining first and second stops. The locking coil is located within the cage, and the first and second tangs are positioned proximate the first and second stops of the cage. The first tang engages the first stop when the nut lock is turned in a first direction, and the second tang engages the second stop when the nut lock is turned in a second direction.

Abstract: A locknut (12) has an L-shaped slider (18) formed of a washer-like piece (19) held above a nut (13) by a contiguous spring element (20) spot-welded to the nut. The spring causes the washer to press against a bolt (33) or stud with locking torque when the locknut is secured thereon, and to rest away from the nut when not adjacent a bolt or stud. While the locknut is being tightened or loosened, a wrench (29) forces the spring against the nut so the washer surrounds a bolt or stud without contacting it. A skirt (43), of straight or downwardly-curved cantilevers (46, 46a) may be disposed on an annulus secured to a surface of the nut opposite the washer, for additional locking torque.

Abstract: Self-locking nuts help prevent the nut from backing off of a spindle or other type of threaded shaft. A single piece nut assembly is provided that is self-locking and comprises a nut subassembly and a washer subassembly. Nut and washer subassemblies are secured together, and do not require any special tools for installation or removal. The washer has an edge which is formed/rolled over a lip extending from the bottom edge of the nut when assembled to provide the unitized assembly. The nut and washer are held apart by a spring, such as a wave spring, until the washer contacts the face of the object to which the nut is being secured. At this point the spring is compressed to engage the nut with the washer, and engage holding elements located in the nut with a holding feature located on the washer and prevent movement between the washer and nut.

Abstract: A screw connection having a screw section and a nut threaded thereon. A self-locking effect of the nut on the screw section is achieved in a simple manner in that an intermediate disk is supported non-rotatably on the screw section and is received on the nut so as to be rotatable relative to the nut. The intermediate disk includes a grid distributed around the circumference of the intermediate disk, and the nut carries at least one resiliently elastic, radially displaceable catch formed by a sheet-metal part which, after installing the nut, positively engages the grid to lock the nut against rotation relative to the screw section and intermediate disk. Upon application of a wrench to the nut, the at least one resilient, radially displaceable catch is compressed and drawn out of engagement with the grid, so that the nut can be rotated relative to the screw section.

Abstract: A lock nut device consists of a lock nut (22) and a lock spring (31). The spring is bent into an U-shape and extends in a axial plane over the nut. It has spring legs (32) lying in grooves (25) in the nut and has end portions formed for engagement with the profile portion (16) on a non-rotatable element (4). In the engagement position, the legs are at such a distance from the nut surface that, with the aid of a socket forced over the nut, they can be pressed towards the nut surface, thus moving the end portion from the engagement position.

Abstract: A locking fastener assembly for axle bearings and the like is free spinning during tightening and removal and is positively held against rotation after installation. The assembly is engageable with an axially slotted male threaded member and includes a nut with female threads and a flange end. A retainer washer includes spaced fingers formed around the nut flange for rotatably supporting the washer at the flanged end of the nut. The washer includes a tab received in the slot of the male threaded member permitting the nut to move axially but not to rotate on the male threaded member. When the nut is engaged by a wrench, the wrench releases a flexible and resilient locking clip to permit the nut freely to rotate. After the assembly has been threaded onto the male threaded member, removal of the wrench frees the locking clip and a lock finger is received in a space between fingers of the retainer washer positively to prevent further rotation of the nut.
