Abstract: A locknut having a polygonal body portion with a frustoconical crown extension at one end. A plurality of indentations are provided in selected flat surfaces of the body portion to form a corresponding number of locking regions in the bore of the nut. Each indentation is curved so that the ends of the indentation are deeper than the crest. As a result, the locking regions also are curved but flatter than the initial curvature of the bore, whereby added contact is provided between the locking regions and a mating male member.

Abstract translation: 一种具有多边形主体部分的锁紧螺母，其一端具有截头圆锥形延伸部。 在主体部分的选定的平坦表面中设置多个凹口，以在螺母的孔中形成相应数量的锁定区域。 每个压痕都是弯曲的，使得凹痕的端部比峰顶更深。 结果，锁定区域也比孔的初始曲率弯曲但平坦，由此在锁定区域和匹配的阳构件之间提供添加的接触。
