Thread cutting (threading) is a method to create helical patterns on a cylindrical or conical object to mate it with other parts. The friction is enough to prevent a rotational movement. Threaded components are also commonly used to convert a linear movement to rotation, or vice versa.
Probably, the most common threaded components are screws and nuts, but threads are found on many components. Most threads are manufactured according to metric or imperial standards. This is very practical since there is a variety of specifications to threads. Some of them are minor and major diameter, the thread's angle, the number of thread at start, length between threads, the number of threads when it is rotated 360 degrees, left or right- or left-handed threads and so on.
Most workshops can make threads. Threads can be made in thread rolling machines, which is suitable for high volumes and threads with a small diameter. Another way the thread is cut, which is done in lathes, milling machines or CNC centers, typically for small series or large diameters.
Two cutting tools are normally used for thread cutting; taps and dies. Dies creates external threads, and taps are for internal threads.
Cutting the external threads is known as threading or in some cases chasing, meanwhile cutting internal threads is called tapping.
Post project to suppliers with Thread Cutting capabilities
A supplier is sought to provide allthread studding on two different sizes of rod. These items were previously bought off-the-shelf; however, the client is now unable to locate the rods in the lengths they require. Suppliers are invited to quote for either full supply or cutting to length only. There is an immediate order to place for this enquiry, making it an ideal opportunity to fill immediate capacity.
**Due to the current health climate, we ask that you only submit a quotation for this project if you are in a position to fulfil the requirement. Please also be mindful that there may be a delay in buyer response due to widespread remote working.**
This company has an immediate order to place to thread the attached brass rod on both ends. Quotes are sought for 1300 rods, which will be free-issued. Threading is the only requirement for this enquiry. Quality and accuracy of the thread is particularly important, as is on-time delivery. Because this is an urgent requirement for their client, should a suitable quote arrive quickly, the work will be awarded early. Those that are interested in being considered for this job are asked to make contact with the buyer directly to discuss; in addition, this could result in further opportunities once quality and reliability have been proven.

Threading of the attached mounting boss is required by a buyer working in the automotive industry. This project calls for left-handed threading of a 1.25mm mild steel bar, with 1 off required at this time. There is an immediate order to place and - although this is a one-off order - additional work of a similar ilk will also be made available to the successful supplier.
