Die M18x0.5 left-hand HSS 800 DIN 22 568 – left-hand ultra-fine thread for structural materials
The M18x0.5 left-hand die is an exceptionally specialized round tool made of high-speed steel (HSS) with a hardness of 64 HRC, combining a diameter of 18 mm with a left-hand ultra-fine thread with a pitch of 0.5 mm. This highly distinctive combination is used in precision rotating machinery where the operating direction of rotation requires a left-hand thread and the absolute maximum leak tightness and vibration resistance are also required. The HSS 800 designation indicates a material intended for machining steels with a tensile strength Rm of up to 800 MPa. Compliance with DIN 22 568 and a tolerance of 6g ensure proper fit with 6H left-hand nuts. This tool is intended for the most specialized workshops handling applications with the highest requirements.
Key advantages of the M18x0.5 left-hand ultra-fine thread die
- Left-hand ultra-fine thread with a pitch of 0.5 mm – a truly unique combination providing maximum protection: a left-hand direction to prevent unscrewing and an ultra-fine pitch to resist vibration-induced loosening with the highest leak tightness
- Diameter of 18 mm for specialized applications – a size used in precision rotating machinery, instrumentation, and equipment requiring a left-hand thread with the very highest performance
- HSS 800 steel with a hardness of 64 HRC – the material enables prolonged cutting of left-hand ultra-fine threads in structural steels up to 800 MPa despite the extremely large number of thread turns
- Tolerance class 6g according to ISO – medium accuracy with controlled clearance ensures a proper fit in precision left-hand mechanisms requiring absolute stability
- Solid round construction – one-piece construction eliminates cumulative errors that are absolutely critical with an ultrafine left-hand pitch and ensures maximum repeatability
The M18x0.5 left-hand die is a highly specialized tool for workshops servicing precision rotating machinery, inspection and measuring equipment, and critical structures where the direction of rotation requires a left-hand thread and sealing and reliability requirements are at the very highest level in steels up to 800 MPa. Due to the exceptionally unique combination (left-hand + ultrafine pitch of 0.5 mm), threading requires operators with the highest qualifications and certification in ultrafine left-hand threads, as well as intensive automatic lubrication with the highest-quality lubricants.
Frequently asked questions
Prepare the rod (diameter 17.9-17.95 mm) with a carefully machined chamfer. Clamp it as securely as possible to eliminate any vibration. Turn the die to the left (counterclockwise), making one full turn forward and half a turn back to the right. With an ultrafine left-hand pitch of 0.5 mm in steel up to 800 MPa, check perpendicularity continuously and lubricate every turn or more frequently.
An ultrafine left-hand pitch in steels up to 800 MPa requires the most intensive lubrication possible. Use only the highest-quality threading oils for the heaviest-duty applications, applied generously before every turn. A diameter of 18 mm and a left-hand pitch of 0.5 mm generate an extremely large number of chips – a top-grade automatic lubrication system is mandatory.
Remember that backing off a left-hand die requires turning it to the right. An ultrafine left-hand pitch of 0.5 mm generates the greatest possible number of chips. At the slightest increase in resistance, immediately turn to the right (clockwise) to back off the die. Clean the flutes very thoroughly and verify the rod diameter with a micrometer (tolerances are extremely tight). Resume only with the highest possible reversal frequency (every 0.5-0.75 turns) and fresh, highest-quality lubricant, under the supervision of a certified specialist experienced in ultrafine left-hand threads.
