The left-hand thread is essential for applications where a reverse thread is required, such as in certain rotating assemblies or for locking purposes.

Ideal use cases

• Cutting left-hand metric coarse threads in steel, stainless steel, cast iron, and non-ferrous metals.
• Maintenance and repair work where a left-hand thread is specified.
• General purpose threading in workshops and manufacturing environments.

Good to know

The tap conforms to DIN 352, ensuring compatibility with standard tap wrenches and threading practices. The bright finish provides a clean surface and helps prevent corrosion during storage. Always use appropriate cutting fluid for the material being threaded.
