摘要：An anti-cross threading screw (1) includes a first threaded portion (4) including a first thread (5) having a first outer diameter (6) and a first pitch (9) and a second threaded portion (12) having a second thread (13) having second outer diameter (18) and a second pitch (21). The second threaded portion (12) is designed as an anti-cross threading portion. The second thread (13) has enlarged an thread crest (15). The second outer diameter (18) of the second thread (13) is smaller than the first diameter (6) of the first thread (5). The first pitch (9) of the first thread (5) is different than the second pitch (21) of the second thread (13).
