还是螺纹

大脸吴

Allthreaded features shall have a countersink or chamfer, countersink diameter equalto the major diameter by 90°, chamfers diameter equal to the minor diameter by 90°.

所有带螺纹的部位应倒角或加工一个沉头孔，沉头孔的直径在90°角度上与螺纹大径相等，倒角直径在90°上与螺纹小径相等。

It seems like the "all threaded features" here are intersections between part surfaces and threaded areas instead of fastener or screw threaded features.
