攻螺纹、套螺纹及其注意事项常用的在角螺纹工件，其螺纹除采用机械加工外，还可以用钳加工方法中的攻螺纹和套螺纹来获得。攻螺纹（亦称攻丝）是用丝锥在工件内圆柱面上加工出内螺纹；套螺纹（或称套丝、套扣）是用板牙在圆柱杆上加工外螺纹。 一、攻螺纹 1.丝锥及铰扛 （1）丝锥 丝锥是用来加工较小直径内螺纹的成形刀具，一般选用合金工具钢9SiGr制成，并经热处理制成。通常M6～M24的丝锥一套为两支，称头锥、二锥；M6以下及M24以上一套有三支、即头锥、二锥和三锥。 每个丝锥都有工作部分和柄部组成。工作部分是由切削部分和校准部分组成。轴向有几条（一般是三条或四条）容屑槽，相应地形成几瓣刀刃（切削刃）和前角。切削部分（即不完整的牙齿部分）是切削螺纹的重要部分，常磨成圆锥形，以便使切削负荷分配在几个刀齿上。头锥的锥角小些，有5～7个牙；二锥的锥角大些，有3～4个牙。校准部分具有完整的牙齿，用于修光螺纹和引导丝锥沿轴向运动。柄部有方头，其作用是与铰扛相配合并传递扭矩。 （2）铰扛 铰扛是用来夹持丝锥的工具，常用的是可调式铰扛。旋转手柄即可调节方孔的大小，以便夹持不同尺寸的丝锥。铰扛长度应根据丝锥尺寸大小进行选择，以便控制攻螺纹时的扭矩，防止丝锥因施力不当而扭断。 2.攻螺纹前钻底孔直径和深度的确定以及孔口的倒角 （1）底孔直径的确定
