摘要： A fastener system includes a screw or bolt having two interleaved helical threads, which bracket a helicoil. The helicoil expands and torques by various means to maintain hold and purchase between the screw coil combination and the substrate into which the screw and helicoil are inserted even when the substrate recedes a significant distance from the screw and helicoil combination. The fastener system includes means for latching the tilt of the coil so as to minimize the constraining forces and optimize the motion of the helicoil, that results in the screw or bolt being pushed into the substrate.

摘要： A pin with threads that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members. The interaction of the threads with the framing members cause the pin to rotate as the threads pass through the framing members and fastens the framing members together. A pin with curved wings that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members. The interaction of the wings with the framing members cause the pin to rotate as the wings pass through the framing members and fastens the framing members together.

摘要： The roots of the box threads in a drill collar or heavyweight drill pipe are configured to reduce the connection stresses encountered during drilling and makeup of the connection. The thread root design in the box reduces fatigue damage caused by makeup torque and cyclic stressing of the engaged drill string connection as it is rotated around curved sections of the well bore. A conventional V-type thread form in the box is provided with an enlarged root radius having its center point offset from the centerline of the opposing thread flanks. The load flank of the thread tangentially engages the arc of the root. The stab flank of the thread is intersected by the enlarged root radius extending to a flat intersecting surface that may extend as far up as the thread pitch diameter.

摘要： A connector that receives a threaded apparatus and reduces stresses induced from the treaded apparatus into the connector is described. The connector includes a top side, a bottom side, and an opening that extends therethrough. The opening is defined by an inner surface that includes a threadform including a plurality of threads. The threads extend radially outward from the inner surface into the connector opening and include a first thread portion and a cutback that extends through a portion of the threadform. The cutback facilitates less stresses being induced into the first thread portion.

摘要： A left hand helical flute crosses right hand threads on a pin inserted into a hole in materials to be joined. A nut smoothly cooperating with the pin threads has a top portion that has three convex, equilateral sides meeting at apices capping their deformable crests. To work the nut, three irregular faces of six within a socket first apply tangential torque at locations near the nut apices. Tightening develops resistance and as the rotating nut slows down, the socket's irregular faces displace nut crest material circumferentially. Torque rises and demand reaches maximum when the socket faces coincide with the nut apices. Thereafter, the nut stops rotating, and the working surfaces move toward disengagement. Torque dips, but rises again when three flat faces of the socket take a second pass at residual nut crest material. Now to deliver radial torque, they crush some underlying nut thread portions that straddle the pin flutes and lock the threads to defeat vibrational forces tending to unwind the nut in service application.

摘要翻译： 左手螺旋槽在插入待接合材料的孔中的针上穿过右手螺纹。 与销螺纹平滑配合的螺母具有顶部，该顶部具有三个凸起的等边侧面，顶部顶点覆盖其可变形顶部。 为了工作螺母，六个插座内的三个不规则面先在螺母顶点附近的位置施加切向扭矩。 紧固发展阻力，随着旋转螺母减速，插座的不规则面向周向移位螺母顶部材料。 当插座面与螺母顶点重合时，扭矩上升和需求达到最大值。 此后，螺母停止转动，工作面向脱离状态移动。 扭矩下降，但是当插座的三个平面在剩余的螺母顶部材料上进行第二次通过时，会再次上升。 现在要提供径向扭矩，它们挤压一些跨在销槽上的下面的螺母螺纹部分，并锁定螺纹以消除在使用中倾向于松开螺母的振动力。
