Die M25x1.5 HSS DIN 22 568 – a metric fine threading tool for vibration-resistant joints

The M25x1.5 die is a professional round tool made of high-speed steel (HSS) with a hardness of 64 HRC, designed for cutting external metric fine threads with a diameter of 25 mm and a pitch of 1.5 mm. At this diameter, the fine thread provides increased vibration resistance and better fatigue strength than the standard M25x3 thread. Its design complies with DIN 22 568, and its 6g tolerance ensures proper fit with 6H nuts in applications requiring stable threaded connections. This tool is ideal for the automotive and machinery industries, and wherever connections must resist dynamic loads and self-loosening.

Why choose the M25x1.5 metric fine thread die

  • Fine thread with a 1.5 mm pitch – a pitch significantly finer than the standard 3 mm increases the load-bearing area of the connection and improves resistance to vibration loads in dynamic applications
  • Diameter of 25 mm for versatile applications – a common size used in the automotive industry, precision machinery, and structures requiring reliable medium-sized threaded connections
  • High-speed steel HSS 64 HRC – ensures long tool life when cutting threads in structural steels with a tensile strength of up to 800 MPa, aluminum, and brass
  • 6g tolerance according to ISO – standard medium fit with normal clearance allows easy nut assembly without the risk of binding in typical applications
  • Solid round construction – construction without separate segments eliminates dimensional errors and ensures dimensional repeatability in batch production of threaded components

The M25x1.5 die is a tool chosen by machine shops, maintenance departments, and manufacturing plants specializing in components subjected to dynamic loads. It is particularly recommended for cutting threads on rods, pins, studs, and shafts in the automotive industry, agricultural machinery, and industrial equipment, where joint stability and vibration resistance are essential for safe operation. Use with threading lubricants is recommended to achieve a smooth thread surface and extend cutting edge life.

Frequently asked questions

The M25x1.5 thread has half the pitch of the standard M25x3 thread, which means twice as many thread turns per unit length. This results in a larger contact area, better vibration resistance, and higher fatigue strength in applications subjected to dynamic loads.

The recommended blank diameter ranges from 24.6 to 24.7 mm. Precise rod preparation is essential for achieving a full metric fine thread profile without excessive resistance during cutting.

This thread is used in the automotive industry (suspension and brake system components), agricultural machinery exposed to vibration, industrial equipment operating under variable loads, and wherever a standard thread could loosen during operation.
