Tapping screws 自攻螺釘

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標準的過程中，一些自攻釘的頭高和頭部尺寸發生了改變。更進一步，沉頭自攻釘的頭部角度由之前的80°變為90°，生產沉頭的廠商須遵循ISO 15065的標準要求(DIN EN ISO 15065-2005頭部外形合乎ISO 7721標準的沉頭螺釘的埋頭孔)。
