Tang Break Tool (Drive connector 1/4") No. 6

• for removing the driving tang after a V-COIL wire thread insert has been installed
• for thread repair work where the tang must be cleared before screw assembly
• for workshop use after the insert sits below or flush with the required installation position

Note Use the tang break tool only after the insert is correctly positioned in the repaired internal thread.

• The tool addresses the final tang removal step after insert installation.
• A dedicated tang break tool reduces uncontrolled impact on the repaired internal thread.
• Numbered tool selection helps match the tool to the intended V-COIL repair range.
• The process separates insertion from tang removal, which supports clean workflow control.

• The tool only removes the tang after installation, so use inserting and extraction tools separately for those process stages.

1. Confirm that the wire thread insert is fully installed in the prepared receiving thread.
2. Align the tang break tool with the installed insert and the thread axis.
3. Apply a controlled breaking movement to remove the tang.
4. Remove the broken tang from the hole or component.
5. Check that the first usable thread turns are clear before assembly.
6. Inspect the repaired thread according to your workshop release process.
