Die M20x2 left-hand HSS DIN 22 568 – left-hand fine threading on medium cross sections
The M20x2 left-hand metric die is a professional round die for cutting external left-hand threads with a diameter of 20 mm and a fine pitch of 2 mm. Made from high-speed steel (HSS) hardened to 64 HRC, compliant with DIN 22 568, it guarantees high dimensional accuracy in applications requiring reverse-direction threads. The M20x2 left-hand threading die is intended for use in structural steels with a maximum tensile strength of 800 MPa and nonferrous metals.
Key features of the M20x2 left-hand HSS round die
- Left-hand metric fine thread – dual protection through the left-hand direction and increased number of thread turns for high strength
- Hardened to a hardness of 64 HRC – ensures lasting edge sharpness when repeatedly cutting left-hand fine threads
- Fine pitch of 2 mm at a diameter of 20 mm – high thread density improves strength and resistance to varying loads
- Medium tolerance class 6g per DIN 22 568 – general-purpose clearance fit with controlled clearance for standard applications
- Solid round construction – solid body construction eliminates deformation when machining medium-diameter shafts
This die is used in rotating machinery, mechanical transmissions, and wherever the direction of rotation requires the joint to be secured. Tolerance 6g ensures compatibility with 6H left-hand nuts. Mechanical workshops use the M20x2 left-hand die in the production of industrial spindles rotating clockwise, transmission components, and wherever protection against self-loosening is required together with high strength under intense vibration.
Frequently asked questions
The LH designation stands for Left Hand, meaning a left-hand thread. This type of die cuts a thread that turns counterclockwise when tightened, unlike standard right-hand threads. It is used in machinery rotating clockwise to prevent self-loosening.
The outside diameter of the rod should be 19.75-19.90 mm in accordance with tolerance 6g specified in DIN 22 568. Chamfer the leading end of the rod at 45° over a length of 5 mm before starting to cut the left-hand thread.
Yes, die stocks are universal and suitable for both right-hand and left-hand threads. The only difference is the direction of rotation during threading - a left-hand die is turned counterclockwise instead of clockwise, using the same half-turn backing-off technique.
