    Abstract: A prevailing torque fastener comprising an externally threaded shank having a locking portion comprising a displaced thread segment including an offset root and a correspondingly offset crest. When engaged with a mating internal thread, the locking portion causes the mating thread to deform at its minor diameter with little or no deformation at its pitch or major diameter.

    Abstract: A method and fastener assembly for preloading a joint wherein a pin having a shank and a head at one end is disposed with the shank portion passing through aligned apertures of a plurality of workpieces to be joined. The shank portion of the pin extends beyond the surface of the workpiece and is provided with an irregular surface configuration. A deformable collar having an initially smooth surfaced internal bore is disposed about the pin and snugged against the adjacent workpiece by a removably positioned means placed in abutting relationship against the free surface of the collar to lightly clamp the joint assembly together to remove free play in the joint. The collar is radially inwardly deformed by a crimping tool so that the initially smooth surfaced internal bore of the collar is deformed to assume a configuration complimentary to the irregular surface configuration of the pin shank and upon continual application of the crimping force an axial elongation of the collar and the shank of the pin is effected to provide a predetermined tension or preload on the joint assembly. After the collar has been deformed, the means to snug the joint together initially is removed.

    Abstract translation: 一种用于预加载接头的方法和紧固件组件，其中在一端具有柄和头的销被布置成使得柄部穿过待接合的多个工件的对准的孔。 销的柄部分延伸超过工件的表面并且设置有不规则的表面构造。 具有初始平滑的表面的内孔的可变形的套环围绕销设置并且通过可拆卸地定位的装置紧贴在相邻的工件上，该装置被置于与套环的自由表面邻接的关系中，以轻轻地将接头组件夹紧在一起，以消除在 联合。 套环通过压接工具径向向内变形，使得套环的初始光滑的表面内孔变形以呈现与销柄的不规则表面构型互补的构造，并且当连续施加压接力时，轴向伸长 套筒和销的柄部被实现以在接头组件上提供预定的张力或预载荷。 在衣领已经变形之后，最初将连接在一起的手段被去除。

    Abstract: A bracket clip to be secured to a vertical support post such as an H-post used in the construction of open shelving units. The clip is provided with a pair of extending tab members offset at an angle with the tabs adapted to be engaged in a trapezoidalshaped slot in the support post. The tabs of the clip are inserted in the slot in the support post while the clip is maintained at an angle and the clip is rotated to engage the tabs within the slot in the support post so that the tabs grip the post and securely fix the bracket clip to the post.
