Abstract
The invention concerns a fastener bolt with a threaded section (A) and a borer section (C). Located between these two sections (A and C), is an unthreaded shaft section (B) whose diameter (D1?) is less than the root diameter (D3?) of the threaded section (A) and the diameter (D2?) of the borer section (C). This smaller-diameter shaft section (B) is manufactured by a press or forging process from a blank with a larger-diameter shaft.
