M20 left-hand HSS die – a robust tool for medium-sized reverse threads
The M20 left-hand HSS die is a professional tool designed to cut external left-hand threads with a diameter of 20 mm and a pitch of 2.5 mm. The construction measuring 45 x 18 mm ensures stability during machining, while the high-speed steel (HSS) construction ensures durability when working with a variety of structural materials.
Advantages of the M20 left-hand die in everyday workshop use
- Left-hand (LH) direction enables the production of threads resistant to self-loosening in rotary mechanisms and tensioning systems
- Durable HSS steel allows threading of materials with strengths up to 800 MPa, including alloy and stainless steels
- Dimensions of 45 x 18 mm provide the appropriate mass and rigidity for secure tool guidance during machining
- Compliance with DIN 22 568 confirms compliance with 6g tolerance and repeatability of the threads produced
- Type B chamfer facilitates thread starting and centering on the prepared rod
The M20 left-hand die is suitable for manufacturing turnbuckles, steel wire rope tensioners, bearing pullers, and differential mechanism components. It is also used in machine building, where reverse threads prevent joints from separating due to vibration. Choose a proven solution – M20 LH HSS die delivers reliability in every task requiring a left-hand thread.
Frequently asked questions
M20 left-hand threads are used in cable tensioners, tensioning screws, bearing pullers, and mechanisms where rotation or vibration could loosen a right-hand threaded joint.
The technique remains the same as for right-hand threads – only the direction of rotation changes, and it should be counterclockwise. Lubrication procedures remain unchanged.
It is not required. The outside diameter of 45 mm fits standard die stocks, so standard workshop equipment can be used.
