M3 left-hand HSS die – a precision tool for small left-hand threads
The M3 left-hand HSS die is a specialized tool for cutting external left-hand threads with a diameter of 3 mm and a pitch of 0.5 mm. Its compact design measuring 20 x 5 mm enables precise work on small components, while its high-speed steel (HSS) construction ensures cutting edge durability when machining various materials.
Advantages of the M3 left-hand die in precision applications
- Left-hand geometry (LH) enables connections protected against self-loosening in mechanisms exposed to vibration
- HSS high-speed steel allows threading of materials with strengths up to 800 MPa, including stainless steels, brass, and aluminum
- Compact dimensions of 20 x 5 mm ensure convenient handling and precise guidance when working with thin rods
- Compliance with DIN 22 568 ensures a tolerance of 6g and an accurate fit with standard nuts
- Form B chamfered lead-in facilitates tool centering and starting the thread without damaging the material
The M3 left-hand die is suitable for manufacturing measuring instrument parts, adjustment screws for electronics, model-making components, and locking mechanisms for optical equipment. It is also used to repair equipment where connections must resist loosening under vibration. Choose a tool for tasks requiring precision – M3 LH HSS die provides reliability in every component requiring a left-hand thread.
Frequently asked questions
M3 left-hand threads are used in electronics, precision optics, model making, and measuring instruments – wherever vibration could loosen a standard right-hand connection.
Left-hand tools have an "LH" marking on the body. In addition, the threads inside the hole run in the opposite direction to those in the standard version.
No, the tool with a diameter of 20 mm works with standard workshop die stocks. The only difference is the direction of rotation – counterclockwise.
