螺纹 Screw thread

（重定向自Thread pitch）
Right- and left-handed screw threads
1871年的车床，有配合的导螺杆及齿轮可以车螺丝的螺纹
Internal and external threads illustrated using a common nut and bolt. The screw and nut pair can be used to convert torque into linear force. As the screw (or bolt) is rotated, the screw moves along its axis through the fixed nut, or the non-rotating nut moves along the lead-screw.
Screw thread, used to convert torque into the linear force in the flood gate. The operator rotates the two vertical bevel gears that have threaded holes, thereby raising or lowering the two long vertical threaded shafts which are not free to rotate (via bevel gear).

螺纹（Screw thread）是一个环绕圆柱体侧面的螺旋倾斜面的连续凸起（此凸起又称为「螺牙」）。

若以螺纹位置区别， 螺旋线位在圆柱体或圆锥的外表面者为外螺纹，而螺旋线位在圆柱孔或圆锥孔的表面者称为内螺纹。若按照螺旋线旋转方向来分类，以顺时针方向旋转向前螺旋推进为右螺纹，依逆时针方向旋转螺旋推进为左螺纹。

螺纹在机械工程应用非常广泛，经常使用于机件的链接和动力传递等。

Right- and left-handed screw threads
The right-hand rule of screw threads.

A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a fastener.
