Thread Repair Kits M 50 x 3.0 - 1.5D

• for repairing damaged internal threads with the original designation M 50 X 3.0
• for V-COIL repair workflows using coordinated preparation and insert installation steps
• for maintenance, repair workshop, field service, and mechanical engineering use
• for selecting a complete repair route by thread size and insert length

Note Use the kit as a process sequence and do not mix components from different thread sizes unless the repair data confirms the match.

• Kit format supports a coordinated thread repair workflow for one original thread size.
• Thread designation M 50 X 3.0 keeps repair selection tied to the damaged internal thread.
• Insert length in the title supports repair planning where the length is specified.
• Process structure helps separate drilling, STI tapping, insert installation, and final checking.

• A repair kit still requires correct sequence and alignment, so do not skip component checks before starting the repair.

1. Identify the damaged internal thread as M 50 X 3.0.
2. Check that the repair kit variant matches the repair requirement.

5. Clean the prepared receiving thread.
6. Install the wire thread insert with the suitable inserting tool.
7. Remove the tang where the selected system requires it.
