Die M22x1.5 left-hand HSS DIN 22 568 – left-hand fine threading on medium cross sections

The M22x1.5 left-hand metric die is a professional round die for cutting external left-hand threads with a diameter of 22 mm and a fine pitch of 1.5 mm. Made from high-speed steel (HSS) hardened to 64 HRC, compliant with DIN 22 568, it ensures high dimensional accuracy in applications requiring reverse-direction threads. The M22x1.5 left-hand threading die is intended for use in structural steels with a maximum tensile strength of 800 MPa and in nonferrous alloys.

Key features of the M22x1.5 left-hand HSS round die

  • Left-hand fine thread with a 1.5 mm pitch – protection against loosening plus increased strength thanks to high thread density
  • High-speed steel (HSS), 64 HRC – ensures long service life when repeatedly cutting left-hand fine threads
  • Fine pitch of 1.5 mm at a diameter of 22 mm – a high number of thread turns improves mechanical strength and vibration resistance
  • Medium tolerance 6g according to DIN 22 568 – general-purpose clearance fit with a maximum clearance of 0.15 mm for standard applications
  • One-piece round design – solid body ensures stability 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 M22x1.5 left-hand die in the production of industrial spindles rotating clockwise, transmission components, and components exposed to intense vibration requiring protection against self-loosening together with high mechanical strength.

Frequently asked questions

Class 6g defines a medium degree of accuracy with controlled axial clearance, allowing easy assembly with 6H left-hand nuts. It is a general-purpose standard for mechanical joints in rotating machinery and transmissions requiring reverse-direction threads.

The tool is designed for structural steels with tensile strengths up to 800 MPa and nonferrous metals such as aluminum, brass, and gray cast iron. The maximum workpiece material hardness is 37 HRC.

Chamfer the end of the rod at 45°, secure the workpiece in a vise or chuck that prevents vibration, and keep the die perpendicular to the axis. Use a die stock with a lever or a machine drive, turn counterclockwise instead of clockwise, back off half a turn every two full turns, and apply plenty of threading oil.
