摘要： A tamper-proof, precision, torque limiting nut device is disclosed. The device comprises an inner collar member having a threaded bore to receive a bolt, stud or the like and an outer sleeve member interconnected to the collar by pins or by welds having a shear strength up to a predetermined torque value. The nut can be tightened on a bolt or stud up to the predetermined shear value, above which the pins or welds shear, to achieve tightening of the nut to the desired torque without the use of a torque wrench. Overtorquing and undertorquing are prevented, and tampering with the nut is substantially obviated.

摘要： An improved deformable locking fastener system comprises a fastener, a deformable collar and a dedicated installation tool. The fastener has a threaded exterior defining a plurality of axial flutes which are configured to prevent of the collar from prematurely captivating the fastener during installation. The collar comprises a cylindrical forward portion, a central portion having an elliptical cross-sectional shape and a rearward portion having an elliptical cross-sectional shape. The collar portions have axial heights selected to maximize the strength of the collar and to minimize the weight of the collar. The installation tool contacts the collar along driving ridges which reduces the radial compression of the collar and increases the tangential driving force turning the collar during installation. In addition, the installation tool includes oblique driving ridges and exit vents which prevent premature cam-off of the installation tool when generating a desired preload and swaging the collar onto the fastener to lock the components together.
摘要翻译：改进的可变形锁定紧固件系统包括紧固件，可变形环和专用安装工具。紧固件具有限定多个轴向槽纹的螺纹外部，其被构造成防止套环在安装期间过早地吸收紧固件。套环包括圆柱形前部，具有椭圆形截面形状的中心部分和具有椭圆形横截面形状的后部。套环部分具有轴向高度，以使衣领的强度最大化并使衣领的重量最小化。安装工具沿着驱动脊接触套环，这减小了套环的径向压缩，并增加了在安装期间转动套环的切向驱动力。另外，安装工具包括倾斜的驱动脊和出口，防止安装工具在产生所需的预载荷时过早地闭合并将套环模压到紧固件上以将部件锁定在一起。

摘要： The invention relates to a bar anchor arrangement for bars subject to tensile stress, whereby the bar anchor (1) consists of an anchor body with a bore provided with an internal thread (5) for screwing in a tension bar (8) provided with an external thread (9) as well as of two parallel eye plates (3) adjoining the anchor body to accomodate an eye bar (10). A smooth tolerance compensating section (6 and 7) is provided on at least one side of the internal thread (5). The length of the external thread (9) of the tension bar (8) essentially corresponds to the minimum screw-in length of the tension bar plus the length of a tolerance compensating section. The length of the internal thread (5) is greater than the minimum screw-in length of the tension bar.

摘要： A retainer bushing for connecting a male member such as a shaft, rod or pin, for example the coupling pin of a motor vehicle clutch pedal, to a mechanical component having a bore accepting the shaft, rod or pin in the bore, for example the input member of a hydraulic master cylinder hydraulically connected to a slave cylinder actuating a clutch release mechanism. The retainer bushing has a flange at one end and one or more longitudinally projecting tangs at the other end. Each tang, which is elastically deflectable outwardly and inwardly, has a radially inwardly directed abutment surface for engagement with the other end of the bore when the flange is engaged at one end thereof, and an inwardly radially directed prong for engagement in a groove formed in the pin. The bushing is introduced into the bore, with the tangs elastically deflected inwardly, until the tangs snap back to their original position with their abutment surface preventing removal of the bushing from the bore, and the tangs are elastically deflected outwardly when the pin is introduced through the bushing bore until each tang snaps back to its original position with its inwardly directed prong engaged in the groove in the pin.A tool permitting disassembly of the shaft, rod or pin from within the retainer bushing is also disclosed.

摘要： A torque indicating nut for use with a complimentary bolt. The bolt and nut assembly is utilized to join sections of electrical bus duct and the electrical conductors contained therein. The torque indicating nut comprises three sections: an engaging section, a driving section and a bridging section. The engaging section is threaded onto the complimentary portion of the previously mentioned bolt and rotated thereon to complete the assembly of adjacent sections of electrical bus duct and the conductors contained therein. When a predetermined value of torque has been reached at the driving section of the torque indicating nut, the bridging section fractures or breaks and falls away.

摘要： An annular piston has a bore threaded to a bolt end and is disposed between a base and a nut in axially spaced relation to the nut, there being an annular cylinder slidably receiving and surrounding the piston and defining an annular pressure chamber therewith, the cylinder being disposed between the base and the nut so that the nut can be tightened to act axially through the cylinder against the base in the absence of any pressure in the chamber. With pressure present in the chamber of a magnitude which tensions the bolt, after pre-tension has been overcome, the nut is free to be rotated to a desired setting.

摘要： A double break-off screw fastener is described, which conceals its mode of fastening by means of a "dummy" free-floating middle shaft. The inventive screw contains three sections, a threaded section which does the actual fastening; a middle shaft section which helps to internally fasten the threaded section before breaking-off; and an outer head section which breaks from the middle shaft, thus leaving the middle shaft in a free-floating state. To the outer observer, the middle shaft is free turning giving the impression of a fastening screw. In reality, however, it is nothing more than a dummy member, which carefully conceals the well hidden internal screw thread.

摘要： The threads at the entrance end of a nut are interrupted by a plurality of circumferentially spaced axially extending flutes to form relatively flexible load distributing threads. The flutes extend axially across a limited number of threads and extend radially into the threads a distance short of the root of the thread. After engagement with a complimentary bolt, and upon the occurrence of a load on the connection, the interrupted threads flex axially of the nut to cushion shock on the bolt threads and shift the zone of maximum stress transfer axially inwardly of the nut, thereby materially extending fatigue life of the connection.
