M20x1 left-hand HSS 800 die DIN 22 568 – left-hand ultra-fine threading, designation 800
The M20x1 left-hand HSS 800 metric die is an advanced round die for cutting left-hand external threads with a diameter of 20 mm and an ultra-fine pitch of 1 mm. Made from high-speed steel (HSS) hardened to 64 HRC with designation 800, compliant with DIN 22 568, it provides the highest dimensional precision in demanding applications. The M20x1 left-hand HSS 800 threading die is designed for use in structural steels with a tensile strength of up to 800 MPa and nonferrous alloys.
Key features of the M20x1 left-hand HSS 800 round die
- HSS 800 designation – material specification indicating a maximum workpiece material tensile strength of up to 800 MPa
- Left-hand ultra-fine thread – triple protection through a left-hand thread direction, an extremely high thread count, and maximum frictional contact area
- Hardened to a hardness of 64 HRC – ensures long-lasting sharpness when cutting ultra-fine left-hand threads
- Ultra-fine pitch of 1 mm at a diameter of 20 mm – extremely high thread count ensures maximum connection strength and leak tightness
- Accuracy class 6g according to DIN 22 568 – general-purpose medium fit with controlled clearance for precision applications
The die is used in high-pressure hydraulics, precision clockwise-rotating spindles, and wherever self-locking protection with the absolute maximum strength is required. Tolerance 6g ensures compatibility with 6H left-hand nuts. Professional workshops use the M20x1 left-hand HSS 800 die in the production of high-pressure hydraulic components operating above 400 bar, precision spindles, and wherever the priority is the maximum number of threads with protection against loosening in medium-diameter assemblies.
Frequently asked questions
The M20x1 left-hand thread is primarily used in high-pressure hydraulic systems, precision clockwise-rotating grinding machine spindles, transmission components, and control valves requiring maximum leak tightness and protection against self-loosening during intensive use.
The outside diameter of the rod should be 19.82-19.92 mm in accordance with tolerance 6g per DIN 22 568. Chamfer the end of the rod at 45° over a length of 5 mm before starting to cut the left-hand thread.
Yes, with its medium diameter of 20 mm, the M20x1 left-hand die is suitable for manual threading using a die stock with a long handle. Secure rod clamping, perpendicular guidance, counterclockwise rotation, and reversing half a turn after each turn with generous lubrication are recommended.
