还是螺纹
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。
这样理解对吗? 请各位大侠赐教。谢谢谢

猜想应该是图纸上的技术要求文字。

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