Metric ISO Thread DIN 13: This standard specifies the exact requirements for metric ISO threads, including the 60° profile and dimensions. A thread according to DIN 13 guarantees high interchangeability and compatibility with matching screws and nuts.

DIN 382: This standard defines the exact dimensions and specifications for hexagon die nuts. It ensures that the tool is precisely manufactured and has a high cutting quality.

Tolerance 6g: The tolerance class 6g is an international standard for external threads (screws). It describes the permissible deviations from the nominal size. A thread cut with a tolerance 6g tool fits perfectly into a matching internal thread with tolerance class 6H.

HSS-G: HSS stands for "High-Speed Steel". The "-G" at the end means that the cutting surfaces are ground. This results in higher precision and a better surface finish of the cut thread. Tools made of HSS-G are particularly robust and resistant to wear and heat.

Follow these steps to repair an external thread with the hexagon die nut:

1. Preparation: Clean the damaged thread area thoroughly of dirt and rust. Make sure the die nut matches the thread diameter and pitch.
2. Positioning: Place the die nut straight onto the beginning of the thread. Carefully turn it by hand until it bites.
3. Cutting: Use a suitable wrench, ring spanner, or socket wrench to turn the die nut slowly and evenly clockwise. Ensure it is always applied straight.
4. Lubricant: During the cutting process, regularly apply cutting oil to reduce friction and extend the life of the tool.
5. Chip Breaking: After every half turn, turn the die nut back a quarter turn to break the chips. This makes the cutting process easier.
6. Completion: Turn the die nut over the entire damaged area. Then, remove it from the thread and clean the finished thread of any chips and oil.

1. What is the main advantage of a hexagon die nut over a conventional die?

The main advantage is its shape. Since it is operated with a wrench, it is excellent for use in confined or hard-to-reach areas where a die stock would be too bulky.

2. What does the designation M 7 x 1.0 mean?

"M" stands for metric ISO thread. The number "7" indicates the nominal diameter in millimeters, and "1.0" is the thread pitch, i.e., the distance between two threads in millimeters.

3. Can I also use this tool to cut new threads?

Yes, technically this is possible. However, the hexagon die nut is primarily designed for the repair and re-cutting of existing, slightly damaged threads. For cutting new threads from scratch, a conventional die set is recommended.

4. Why is HSS-G quality important?

HSS-G steel is particularly hard and wear-resistant. This ensures that the tool maintains its cutting performance even under high stress and in harder materials, which leads to a longer service life.

5. What does Tolerance 6g stand for?

Tolerance 6g is a standard tolerance for external threads (screws). It ensures that the cut thread has a precise fit and functions smoothly with a matching internal thread (nut) according to the standard.
