Abstract: Embodiments of the invention relate generally to nut retention devices and, more particularly, to nut retention devices having a strap that can be fixed to a distal end of a threaded member without damage to the threaded member or nut, thereby permitting their reuse. In one embodiment, the invention provides a nut retention device comprising: a body having a nut engaging opening; and a deformable strap extending from the body, wherein, in an operative state, the nut engaging opening immovably receives a nut that is threaded on a threaded member and the strap is positioned to fixedly engage the threaded member to retain the nut.

Abstract: A radio frequency identification (“RFID”) apparatus includes a housing configured to mate with a channel of an extruded metal mounting system and a flange extending radially outwardly from the housing. The flange is configured to bear upon a lower portion of a channel lip to retain the housing within the channel. In addition, a seat is disposed within the housing to retain an RFID tag and a lock secures the housing at a particular location along the channel.

Abstract: A locknut which defines a multiple of inner apertures about an inner diameter and a multiple of outer apertures about an outer diameter.

Abstract: A lockable nut system for use with threaded steel bar which includes a screw threaded nut for engagement with the threaded steel bar and a locking member which is slidably engageable with the bar. The locking member is adapted to resist rotation about the bar and is also axially engageable with the nut to prevent rotation of the nut. The locking member has one or more fingers to engage the nut with an end of the finger being displaced to engage the nut as a result of deformation of a finger actuating tab or a dished body of the locking member. The locking member may engage the bar by displacement of an end of at least one tongue as a result of deformation of a tongue actuating tab during compression between the nut and a second structure.

Abstract: A union lock for maintaining a union between two conduits is disclosed. In a first embodiment, the union lock includes a pair of bridgepieces. Each of the bridgepieces includes an elongated member. A substantially semicircular flange is coupled to each end of the elongated members. A tab is coupled to each end of the flanges, each tab having a hole formed therein for receiving a connector. During use, the bridgepieces are placed around the conduits and secured to each other by placing the connectors in the holes in the tabs. By tightening the connectors, the elongated members may be compressed against the conduits and against a union nut joining the conduits, thus maintaining the union. In a second embodiment, the union lock includes a pair of elongated members. A substantially circular flange is coupled to each end of the elongated members. A tab is coupled to each end of the flanges, each tab having a hole formed therein for receiving a connector.

Abstract: A nut and bolt securing device is disclosed to prevent loosening of the assembly due to environmental conditions. In a first version of the invention the two piece device is fitted over a nut and a portion of a bolt extending from the nut, the two sections of the device being secured together with set screws, with serrations within the device, and one or more set screws engaging the front end of the device. In a second version of the device a shelf like planar projection on the front end of the device engages a planar surface on a nut, again combining with the serrations within the device to prevent fastener loosening. The device is particularly described in use in conjunction with refrigerant system flare nuts so as to prevent loss of refrigerant at these flare nut unions.

Abstract: An anti-rotation locking assembly for releasably fastening automotive exhaust pipes and exhaust manifolds to an engine block is disclosed comprising a threaded bolt with hex-wrenching recess and a hyperbolic locking plate with hex-stud which fits into the wrenching recess of the bolt and is attached thereto by cotter pin or Q clip. The locking plate has a contour which mates with said exhaust pipe and thereby prevents the bolt from working loose due to vibration of the engine.
