    • A threaded bolt having a shank of basic cylindrical form and with a root end and a head end is provided with a spiral-shaped external thread, which has at least one principal flight and in the vicinity of the root end has at least one lead-in flight, adjoined by the principal flight, where the lead-in flight has a lead-in surface which differs from the principal flight and is formed in order to come into crossing-free engagement with flights of a complementary internal thread of an element. The lead-in flight and the principal flight are interrupted by at least one groove, which extends in the longitudinal direction of the shank in order to form a free space for the accommodation of lacquer residues. The flights and the grooves are initially formed by rolling.
    • 具有基本圆柱形形式的柄和根端和头端的螺纹螺栓设置有螺旋形外螺纹,其具有至少一个主飞行,并且在根端附近具有至少一个引导头, 在飞行中,与主要飞行相连,其中引入飞行具有与主飞行不同的导入表面,并且形成为与元件的互补内螺纹的螺纹无交叉接合。 引导飞行和主飞行被至少一个凹槽中断,该凹槽在柄的纵向方向上延伸,以形成用于容纳漆残余物的自由空间。 飞行和凹槽最初是通过滚动形成的。
