The period subsequent to the industrial revolution has seen the invention of many machines. Machines have become an integral part of life today. We require machines for everyday use as well. If you look closely at any machine, you would find that the screws and the nuts form a very important part of these machines. They play a great role in joining different pieces of the machine together. Imagine what would be the case if we did not have the screw and the nut to fasten them. The machine parts would be flying all over the place. This would make us appreciate the importance of the humble screw and the nut. When you acknowledge the role of the screw, one should also acknowledge the implements that help create the screw in the first place. These implements are the ACME thread taps and die.

The role of the taps and dies:

You know that the industry circles refer to the nut as the female part of the combination and the screw as the male part. In its raw form, the screw would be a simple and small piece of a metal rod whereas the nut would be a small piece of metal with a hole. In case you insert this raw piece of the rod into the hole, it would slip in and out and out quite easily. It would not grasp or hold on to each other firmly. You need some thread on the screw as well as inside the nut for the contraption to grip together.

The ACME thread taps have utility in carving out the threads inside the nuts. These are metal instruments having sharp grooves or teeth at their ends. You have to insert them into the nut and turn them either clockwise or anticlockwise. The surface metal inside the nuts would chip away forming threads with grooves.

Similarly, in the case of screws, you would have to insert the rod or the pipe between two pieces of thread dies. They would form a sort of a clamp holding on to the rod tightly. The turning of the pipe inside the clamp would form threads and grooves on the surface. If you match the pitch of the screw and the nut correctly, they would make an excellent fastening tool that could last forever.

The different kinds of taps and dies:

Every country in the world would have its standardized measurements. The Americans have theirs and so do the British. The basic principle is the same whereas the measurement and sizes of the screw threads would differ. They would have different pitches. You would not be able to use one for the other. Based on the usage, the industry has classified them as follows.

  • Whitworth taps and dies:

    This type of measurement is popular in Britain and the countries once under the rule of the British. The full form stands for British Standard taps and dies.

  • UN thread taps and dies:

    The UN taps and dies are specially calibrated taps and die used for carving threads on pipes that transport liquids and gases. The carving of the threads would be of a higher standard.

Final words:

Without the thread cutting tools, it would be difficult to imagine any kind of industry from functioning.
