摘要: A multi-purpose tool for inserting tanged or tangless wire inserts in a pre-threaded hole. In the case of a tangless insert, the tool nose passes freely through the internal diameter of the insert until a tool pawl automatically engages a cut out formed in the tangless insert. Once the proper depth of the insert in the parent material has been achieved, the tool stops rotating and is reversed for proper disengagement, the installation being complete. In the case of a tanged insert, the nose of the tool does not pass freely through the insert due to the presence of the tang that is blocking its way. As the tool rotates through the internal diameter of the insert, a ledge formed on the nose portion of the tool forces the insert to wind itself in the threads of the parent material. The pawl used to install the tangless insert is positioned directly behind the nose of the tool and remains inoperable in the retracted position since the insert does not have a cut out provided for it. After proper depth of the insert has been achieved, the tool stops rotating and is reversed for proper disengagement.

摘要: A fastener assembly having an elongated shaft with an exterior surface defining a plurality of open-ended longitudinaily-extending splines on one end of the shaft and a second plurality of longitudinally-oriented closed-ended spline circumferentially spaced from the first splines. The assembly includes a substantially triangular retaining ring having an inwardly directed tab is positioned in the middle of each side of the ring. Cross-over slots interconnect the first and second splines and are sized to require the retaining ring tabs to flex to permit transition of the ring tabs between the first splines and the second splines.

摘要: A blind fastener with an improved drive nut and assembly process. The blind fastener includes a screw, a sleeve, a nut, and a drive nut. The drive nut has a smooth bore and protruding nibs that mate precisely with a driving recess located in the nut head. A retaining device is used to retain the drive nut on the screw against the nut. Once the new assembly process for the blind fastener has been completed, the drive nut will have been mated with the nut head to prevent any rotation of the nut during installation of the blind fastener. The assembly process will now include placing the sleeve over the threads of the screw to a position adjacent the screw head. The nut is then threaded onto the screw adjacent the sleeve. The drive nut's protruding nibs are next aligned and physically engaged into the driving recess of the nut head by sliding the smooth bore over the screw. A retaining device is placed over the screw adjacent the drive nut to retain the drive nut to the screw. The retaining device can be an adhesive.

摘要: A fastener system including a blind grounding stud and a sleeve. The sleeve has a first section abutting a second section. The first section has a smaller outer surface diameter than the second section. A knurled band is formed around the first section beginning at the intersection between the first and second sections. The sleeve has an opening axially through the two sections. The opening has a first larger inner surface which tapers via a frusto-conical surface to a smaller diameter inner surface. The larger diameter inner surface extends from the free end of the sleeve first section and extends toward the second section to the frusto-conical surface. The smaller diameter inner surface begins at the free end of the second section and extends toward the first section to the frusto-conical inner surface. The smaller diameter inner surface spans at least a portion and preferably all of the knurled band.

摘要: A fastener assembly which includes a nut held loosely by a cage secured to an inaccessible surface of a panel. Serrations in the facing surfaces of the cage and the nut cause them to mutually interlock when pressed together by a tightened bolt passing through aligned apertures in the panel being fastened and the cage. The mutual interlocking of the nut and the cage, either directly or through an intermediate element, causes the assembly to transfer shear loads imposed by the bolt from the bolt aperture in the inner panel to the points where the cage holding the nut is attached to that panel.

摘要: A stud assembly, for securing a nonstructural decorative panel to the interior of an aircraft, includes a threaded shank fixed to one side of a flat base, the peripheral area of the opposite side of the base being joined to the peripheral area of a flat disc, the opposite side of the flat disc having an adhesive applied thereto, so that, when a nut is tightened on the shank to its proper torque level, the tensile force in the shank allows a dimpling effect in the flat base but not in the flat disc or the panel.

摘要: A blind fastener with an improved drive nut and assembly process. The blind fastener of the present invention includes a screw, a sleeve, a nut, and a drive nut. The new drive nut of this invention has protruding nibs that mate precisely with a driving recess located in the nut head. The protruding nibs of the new drive nut are not deformable and serve to replace the deformable annular ridge that was used in previous drive nut assemblies. The configuration of the protruding nibs and the recess in the nut head can be of many forms, so long as both parts are capable of being mated. Once the new assembly process for the blind fastener has been completed, the drive nut will have been mated with the nut head to prevent any rotation of the nut during installation of the blind fastener. The assembly process will now include placing the sleeve over the threads of the screw to a position adjacent the screw head. The nut is then partially threaded onto the screw until the internal threads within the region of the enlarged nut head have not been completely threaded onto the screw. The drive nut's protruding nibs are next aligned and physically engaged into the driving recess of the nut head. The mated drive nut and nut are next rotated which results in the drive nut and nut being threaded onto the screw as a single unit and, therefore physically locked together.
摘要翻译: 具有改进的驱动螺母和组装过程的盲卡扣。 本发明的盲紧固件包括螺钉,套筒,螺母和驱动螺母。 本发明的新的驱动螺母具有与位于螺母头部中的驱动凹槽精确配合的突出的尖头。 新的驱动螺母的突出的尖头不可变形,并且用于替换先前驱动螺母组件中使用的可变形环形脊。 突出的笔尖和螺母头中的凹部的构造可以是许多形式,只要两个部分都能够配合即可。 一旦盲装紧固件的新组装过程已经完成,驱动螺母将与螺母头配合,以防止在安装盲链紧固件期间螺母的任何旋转。 组装过程现在将包括将套管放置在螺钉的螺纹上至与螺钉头相邻的位置。 然后将螺母部分地拧到螺钉上,直到扩大的螺母头的区域内的内螺纹未被完全拧到螺钉上。 驱动螺母的突出的笔尖接下来对齐并物理地接合到螺母头的驱动凹槽中。 配合的驱动螺母和螺母接下来旋转,这导致驱动螺母和螺母作为单个单元螺纹拧在螺钉上,因此物理上锁定在一起。

摘要: A self-locking fastener system comprises a pin for receipt in a hole in a workpiece and having an external thread which mates with a collar having an internal thread for carrying a tensile load. A plurality of helically extending flutes in the external thread on the pin collectively extend approximately one full revolution around the circumference of the thread. The collar has three longitudinally extending lobes for driving by a deltoid driver socket. When a desired clamp-up load is achieved on a workpiece, the socket plastically deforms the lobes and collar material radially inwardly thereof so that some of the collar material inwardly from each lobe is displaced into the void volume created by a helical flute. This displaced collar material inhibits unscrewing of the collar from the pin.
