    摘要： A female threaded fastener, such as a nut, for preventing cross threading with a male threaded fastener comprises a body in which there is a threaded bore. A mouth is formed on at least one open end of the bore. The mouth has a partial thread section and a lip segment. The partial thread section has formed in it at least one partial thread. The lip section is unthreaded and may be angled radially outwardly from the bore.

    摘要： The invention disclosed herein relates to a fastener assembly and method of using same to preload a joint including a plurality of adjacent workpieces having aligned openings formed therein. The fastener assembly includes a pin member having an enlarged head and a shank located within the aligned openings in the workpieces and further includes a collar member having a deformable outer portion and a relatively hard inner portion located about a portion of the shank such that the inner portion is directly adjacent the shank portion. Also formed on the shank is a thread configuration adapted to cooperate with a complimentary thread configuration for snugging the workpieces together with a relatively light preload. After the joint has been snugged together, the collar member is crimped causing axial flow of material in the outer portion which reacts to stretch the pin member and induce a desired preload in the joint. Radial flow of the material in the outer portion is resisted by the hardened inner portion whereby the collar member does not flow into engagement with the shank portion of the pin member.

    摘要翻译： 本文公开的本发明涉及一种紧固件组件及其使用方法，用于预先加载包括形成在其中的对准开口的多个相邻工件的接头。 紧固件组件包括销构件，该销构件具有扩大的头部和位于工件中对齐的开口内的柄部，并且还包括套环构件，所述套环构件具有可变形的外部部分和相对硬的内部部分，该内部部分围绕柄的一部分设置， 部分直接邻近柄部。 还形成在柄上的螺纹构造是适于与相对于螺纹构造配合的螺纹构造，用于以相对较轻的预载连接工件。 在接头紧贴在一起之后，颈圈构件被卷曲，导致外部部分中的材料的轴向流动，其反应以拉伸销构件并且在接头中引起期望的预载荷。 外部部分的材料的径向流被硬化的内部部分抵抗，由此套环构件不会流入与销构件的柄部分接合。

    摘要： A mobile construction machine comprises a pair of working components pivotally connected together by a pin. The pin has a first stop means secured on a first end thereof to prevent longitudinal movement of the pin in a first direction relative to the components and a second stop means releasably attached to a second end of the pin to prevent it from moving in the opposite direction. Upon removal of the second stop means from the pin, the pin may be removed from aligned bores formed through the components to disconnect the same. Upon reinstallation of the pin, a conically shaped self-centering member is attached to the pin in lieu of the second stop means to facilitate reinsertion of the pin into the bores formed in the components.
