M10 left-hand HSS die – left-hand threading for special applications
The M10 LH die is a specialized tool for producing external left-hand threads on rods, shafts, and pins with a diameter of 10 mm. Made of high-speed steel (HSS) in accordance with DIN 22568, the M10 left-hand threading die is used in mechanisms that prevent self-loosening, rotating machinery, and designs requiring unusual technical solutions with 6g tolerance.
Main features of the M10 left-hand die
- Left-hand thread profile eliminates the risk of self-loosening in equipment with rotary motion
- HSS steel ensures dimensional stability and abrasion resistance under workshop conditions
- Standard pitch of 1.5 mm ensures compatibility with M10 LH left-hand nuts
- The DIN 22568 standard confirms professional workmanship and international quality
- For use in toolrooms and maintenance departments servicing specialized machinery
Mechanics servicing industrial machinery and technicians at manufacturing facilities appreciate the M10 left-hand metric die as a solution for demanding technical applications. This tool is recommended for workshops servicing agricultural equipment, the woodworking industry, and textile machinery with rotating components. Trust a tool that ensures secure joints in special-purpose mechanisms.
Frequently asked questions
M10 left-hand threads are used in angle grinders on the left side of the spindle, circular saws, left-side bicycle pedals, lathe spindles, and gear mechanisms with counterclockwise rotation. They are also used in the woodworking industry on band saw shafts, in textile machinery, and in agricultural equipment with rotating working components secured against loosening.
Components with left-hand threads should be clearly marked with the LH symbol engraved or stamped on the surface. A groove or notch on the screw head is also recommended as a visual warning. In technical documentation, the thread is designated as M10 LH or M10x1.5 LH. Many facilities also use color markings – for example, red paint on the end of the thread.
Yes, the M10 LH die has the same outside diameter as a standard M10 right-hand die, so it fits the same die stock. The diameter of the M10 die is usually 38 mm and requires a die stock with three securing screws. The only significant difference is the direction of rotation during threading – turn the LH die counterclockwise instead of clockwise, maintaining the same forward-and-reverse rhythm.
