    • A tamper-resistant fastener such as a nut for a bicycle has a smoothly rounded generally dome-shaped body and one or more recesses formed into the body. Each recess has a first and open ended portion which is bounded on radially inward side but not on the radially outward side, and a second and closed ended portion which is bounded on both the radially inward side and the radially outward side. Additionally, each recess can have an additional notch formed therein, the recess and notch together forming a major and minor recess. A wall which bounds the radially inward side of the recess decreases in radial distance from the central axis of the nut as the recess proceeds in the circumferential direction. A mating wrench has teeth that match the recesses and, if present, the notches.
    • 诸如用于自行车的螺母的防篡改紧固件具有平滑的圆形的大致圆顶形的主体和形成在主体中的一个或多个凹部。 每个凹部具有在径向向内侧但不在径向向外侧上限定的第一开口端部和限定在径向向内侧和径向向外侧的第二闭合端部。 此外,每个凹部可以具有形成在其中的附加凹口,凹口和凹口一起形成主凹槽。 当凹部沿圆周方向进行时,限制凹部的径向向内侧的壁与螺母的中心轴线径向距离减小。 配对扳手具有与凹槽匹配的齿,如果存在则具有凹口。
