Die M42x4 HSS DIN 22 568 – standard threading on extremely large cross sections

The M42x4 metric die is a professional round die for cutting external threads with a diameter of 42 mm and a standard pitch of 4 mm. Made from HSS steel hardened to 64 HRC, compliant with DIN 22 568, it ensures high dimensional accuracy in the most demanding large-scale applications. The M42x4 threading die is designed for cutting threads in structural steels with a tensile strength of up to 800 MPa and nonferrous metals.

Key features of the M42x4 HSS round die

  • High-speed steel (HSS) hardened to 64 HRC – exceptional cutting edge life during intensive thread cutting at extremely large diameters
  • Standard pitch of 4 mm – a general-purpose thread for a diameter of 42 mm, providing adequate strength and ease of assembly in heavy structures
  • Fit 6g according to DIN 22 568 – standard class with controlled clearance for general-purpose mechanical applications
  • Solid round body – solid construction eliminates deformation when machining shafts and rods with very large diameters
  • Versatility across materials – effective thread cutting in structural steels, aluminum, brass, and gray cast iron

The die is used in heavy industry, mining machinery, and the production of high-tonnage steel structures. Class 6g ensures compatibility with 6H nuts. Professional workshops use the M42x4 die in marine engine overhauls, machining of high-power machine shafts, and the production of parts exposed to extreme loads in the mining and metallurgical industries.

Frequently asked questions

The M42x4 thread is used in mining machinery, marine engines, high-tonnage hydraulic presses, high-power drive shafts, and steel structures requiring threaded connections with very large diameters and resistance to extreme loads.

According to DIN 22 568, the rod diameter for tolerance 6g should be 41.55-41.75 mm. Chamfer the rod end at 45° over a length of 10 mm to facilitate entry of the leading cutting edges and prevent damage to them.

No, at a diameter of 42 mm, manual threading is practically impossible due to the force required. A torque-controlled machine drive, an axially compensating holder, and secure workpiece clamping to eliminate all vibration during thread cutting are mandatory.
