Die M4x0.5 left-hand HSS DIN 22 568 – ultraminiature left-hand metric fine thread
The M4x0.5 left-hand die is an ultraprecision round tool made of high-speed steel (HSS) with a hardness of 64 HRC, combining an ultraminiature diameter of 4 mm with a left-hand metric fine thread with a pitch of 0.5 mm. This exceptionally unique combination is used in the most advanced precision mechanisms, where ultraminiature rotating components require a left-hand thread to prevent loosening, while increased vibration resistance provided by the fine pitch is also needed. Compliance with DIN 22 568 and the 6g tolerance ensure a proper fit with 6H left-hand nuts. This tool is intended exclusively for the most specialized ultraprecision workshops working with microelectronics, the highest-grade optics, and microinstruments.
Main advantages of the M4x0.5 left-hand fine-thread die
- Left-hand metric fine thread at an ultraminiature diameter – an entirely unique combination providing dual protection: the left-hand direction prevents unscrewing, and the fine pitch prevents vibration-induced loosening in ultraminiature applications requiring the highest precision
- Diameter of 4 mm for rotating microcomponents – the size makes the tool suited to ultraminiature rotating rods, micro-adjustment studs, and micropins in precision electronics and micro-optics
- HSS steel hardness of 64 HRC – maintains sharpness despite the extremely small cutting edge dimensions when cutting left-hand metric fine threads in steels, aluminum, and brass
- Tolerance class 6g according to ISO – a standard accuracy grade with controlled clearance ensuring a proper fit in ultraprecision ultraminiature mechanisms with left-hand threads
- Solid round construction – the non-segmented construction eliminates dimensional errors that are absolutely critical at ultraminiature diameters of left-hand fine threads
The M4x0.5 left-hand die is a tool for the very most specialized microprecision laboratories working with ultraprecision microelectronics, microinstrument manufacturing, and nano-optics. It is particularly useful for cutting left-hand fine threads on ultraminiature rotating microstuds and microcomponents where a standard right-hand thread could loosen. Due to the extremely small dimensions and unique combination (left-hand + fine thread + ultraminiature), the process requires working exclusively under a top-grade stereo microscope, the highest operator qualifications with certifications in micromechanics, and exceptional care in a sterile laboratory environment.
Frequently asked questions
Prepare a rod (diameter 3.9-3.95 mm) with a carefully formed micro-chamfer under a stereo microscope. Working under a top-grade microscope is absolutely mandatory. Rotate the die to the left (counterclockwise), making half a turn forward, then a quarter turn back clockwise. When cutting an ultraminiature left-hand fine thread, continuously check perpendicularity under the microscope and avoid any excessive pressure whatsoever.
Use ultraprecision synthetic oils for micromechanics in extremely minute quantities, applied with a micropipette under continuous microscopic observation. At the ultraminiature diameter of 4 mm, excess lubricant completely prevents visual inspection under the microscope. Apply a single extremely minute drop before starting and replenish every few turns with maximum precision.
Ultraminiature cutting edges for left-hand fine threads are the most delicate of all. At the slightest increase in resistance, immediately rotate very gently clockwise (the backing-off direction for a left-hand thread) under continuous microscopic observation. Check the rod diameter under a top-grade microscope (a tolerance of ±0.02 mm is absolutely critical at ultraminiature dimensions). Clean the flutes with an ultraprecision microscopic brush. Resume only with the highest frequency of backing off – every half turn, under continuous visual observation through a microscope by a certified micromechanics specialist.
