Long machine nut screw tap with overrun shaft for cutting nuts for metric threads in steel up to a strength of 800 N/mm².

Long service life


Very long threaded start (approx. 2/3 of the thread length) and up to 4x more teeth compared to conventional machine taps



Specially developed for machining nuts


The groove and thread geometry has been specially designed for machining nuts.



Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze

Notice

Sufficient coolant and lubricant must be added when cutting threads.
