Use this V-COIL wire thread insert refill pack for controlled replacement stock in M 18 x 1.5 repairs. The insert length 9.0 mm and the stated thread designation define whether the insert belongs to the prepared thread and screw connection.
Metric thread selection is based on nominal diameter and pitch, so both values must match the screw connection or drawing. Free running inserts are selected when normal screw running behavior is required after installation. Use the drawing, the existing component, and the required repair workflow as the selection reference. This makes the refill pack specific to thread repair in housings, covers, flanges, brackets, and similar metal components.
- rebuilding a worn or stripped internal M 18 x 1.5 thread after the hole has been prepared for the insert system
- using 9.0 mm inserts when this length is specified for thread engagement or component wall thickness
- keeping spare inserts available for recurring repairs without replacing the complete kit
- controlled maintenance work where thread engagement must be checked after installation
Note Use only with the correct STI tap, installation tool, and thread preparation process for M 18 x 1.5.
- refill pack supports recurring repairs where only inserts are consumed
- thread designation M 18 x 1.5 reduces the risk of mixing similar repair sizes
- V-COIL system structure keeps insert choice linked to the prepared STI thread and length 9.0 mm
- repair concept can retain the original screw size when preparation and installation are controlled
Drawbacks
- This refill pack does not include preparation or installation tools; use a suitable V-COIL repair kit or tool set when the required tools are not already available.
- Confirm that the damaged thread is M 18 x 1.5 and that the selected insert length is 9.0 mm.
- Prepare the hole according to the V-COIL repair process before inserting the wire thread insert.
- Cut the STI thread with the matching STI tap for the repair system.
- Clean the prepared thread so chips do not interfere with insert seating.
- Place the insert on the installation tool and drive it into the prepared thread.
- Remove the tang if the selected insert execution and process require that step.
- Check screw engagement by hand and inspect the repaired thread area.

- When do you choose a refill pack instead of a complete repair kit?
- Choose a refill pack when the required drills, STI taps, inserting tools, and tang tools are already available for the repair system.
- Which thread does this insert match?
- This insert matches M 18 x 1.5. Metric thread selection is based on nominal diameter and pitch, so both values must match the screw connection or drawing.
- What does free running type S mean in assembly?
- Free running type S supports normal screw movement after correct installation and does not add a locking insert function.
- Why is insert length important?
- Insert length 9.0 mm affects the available thread engagement in the repaired component and must match the repair requirement.
- Where can you find V-COIL thread repair technical information?
- Use the Technical information V-COIL thread repair as PDF.
- What should be checked after installation?
- Check that the insert sits below the entry surface where required, that the screw starts smoothly, and that no chips remain in the thread.
- How do you avoid mixing metric pitches?
- Compare nominal diameter and pitch together because metric repair inserts with different pitches are not interchangeable.
- Where can you find the VÖLKEL thread repair catalog?
- Use the VC 23 catalog as PDF.
