过时标准

已废止的德国标准，内螺纹圆柱销，是 ISO 8733 和 ISO 8735 的前身，范围更宽，直至 d 80 mm 和 M42。该销用于盲孔：销用于确定两个零件的相互位置，将拔销螺钉或滑锤拧入一端的螺纹孔，即可把销从没有出口的孔中拔出。销为公差 m6 的磨削圆柱；螺纹端有短倒角，并有带120度锥形沉孔的柱形沉孔，用于保护螺纹。两种型式在无螺纹端有所不同：C 型由不淬硬易切削钢 9SMnPb28K 制成，该端有15度倒角；D 型淬硬至 60 HRC ± 2 HRC，为球面端，球面半径等于直径，并有较短的15度导向锥。涵盖公称直径 6 至 80 mm、螺纹 M4 至 M42、长度 16 至 200 mm。1977 年版于 1992 年被 DIN EN 28733 和 DIN EN 28735 取代，现由 DIN EN ISO 8733（不淬硬销）和 DIN EN ISO 8735（淬硬销）取代。
