The DIN 352 design and ISO 2 (6H) tolerance class provide reliable thread quality for standard fasteners. The bright finish reduces friction and prevents chip welding, while the HSS material withstands the heat generated during manual tapping.

Ideal use cases

• Creating internal M7 threads in steel, cast iron, and non-ferrous workpieces
• Repairing damaged threads in maintenance and repair operations
• Prototyping and small-batch production in workshops

Good to know

For best results, pre-drill a 6.0 mm core hole and use a suitable cutting lubricant. The square drive fits standard tap wrenches.
