Machine Nut Tap FZ HSS-G left hand thread - Tr 14 x 4 LH

• Produce internal threads in nuts and similar short components in mechanical engineering and maintenance.
• Typically used in a machine tool with a suitable tapping chuck or tool holder for controlled feed.
• Best suited for through holes where chip evacuation is reliable, depending on flute form.
• Process: manual driving or assisted driving depending on your holder and machine setup.
• Use: thread cutting, re tapping, and thread cleaning depending on condition.

Note Clamp the nut securely and align the tool to avoid cross threading. Use a stable feed to control chip load.

• Supports series production of threaded nuts with consistent geometry.
• Machine driven operation reduces operator variability compared with manual tapping.
• DIN based execution supports standardized selection.
• Tool change is quick in common machine holders.

• Chip evacuation limits performance in blind holes unless the tool design is specified for that condition.
• Requires stable machine alignment and suitable lubrication to avoid thread damage.

1. Prepare the part so the hole is drilled and deburred and the start is chamfered.
2. Clamp the nut or component securely in the fixture so it cannot rotate.
3. Mount the tap in a suitable machine holder and set a controlled feed and stop position.
4. Apply cutting fluid to the tool and to the hole entry area before you start.
5. Start the tapping cycle and monitor load for signs of misalignment or chip packing.
6. Stop the cycle and retract the tap according to your machine sequence.
7. Clean the thread and remove chips from the part and the tool.
8. Check thread fit with a matching screw or with your inspection method.
