Tapping screws 自攻螺钉

When changing the DIN standards for tapping screws to ISO standards, some head heights and head diameters have been changed. Furthermore, the head angle of countersunk head tapping screws has been changed from 80° to 90°.When manufacturing the countersinks, the applicable specifications of ISO 15065 have to be observed.

在由ISO替代DIN标准的过程中，一些自攻钉的头高和头部尺寸发生了改变。更进一步，沉头自攻钉的头部角度由之前的80°变为90°，生产沉头的厂商须遵循ISO 15065的标准要求(DIN EN ISO 15065-2005头部外形合乎ISO 7721标准的沉头螺钉的埋头孔)。
