    • A fastener includes an elongated shaft having a head at the end, the head comprising a lock fin extending radially outward from the shaft. The head includes an engagement cavity. The fastener further includes a cap having an engagement protrusion for insertion into the engagement cavity of the cap such that rotation of the cap causes corresponding rotation of the head, the cap further comprising a contact portion having a plurality of radially outward facing planar surfaces. The fastener further includes a rotation resisting element having inward facing planar surfaces that fit with the radially outward facing planar surfaces of the contact portion, the rotation resisting element further including an interference feature extending radially outward, the rotation resisting element being resilient so as to allow but resist rotation of the cap with respect to the rotation resisting element.
    • 紧固件包括在末端具有头部的细长轴,所述头部包括从所述轴径向向外延伸的锁定翼片。 头部包括接合腔。 紧固件还包括具有用于插入帽的接合腔中的接合突起的帽,使得帽的旋转引起头的相应旋转,帽进一步包括具有多个径向向外面对的平坦表面的接触部分。 所述紧固件进一步包括旋转阻力元件,所述旋转阻力元件具有面向内的平坦表面,所述内部平坦表面与所述接触部分的所述径向面向外的平坦表面配合,所述旋转阻力元件还包括径向向外延伸的干涉部件,所述旋转阻力元件是弹性的, 但是阻止帽相对于抗旋转元件的旋转。
