V-COIL Wire thread insert type LS M 18 x 1.5 - 9.0 mm

• repairing damaged internal M 18 x 1.5 threads with the V-COIL insert system
• refill stock for repairs requiring insert length 9.0 mm
• free running screw assembly where no locking torque is required from the insert itself
• service work where the original screw size should remain usable after the repair

Note Use only with the correct STI tap, installation tool, and thread preparation process for M 18 x 1.5.

• insert length 9.0 mm gives a clear selection reference for the required repair depth
• M 18 x 1.5 designation keeps the refill pack tied to one defined screw connection
• free running type S supports normal screw movement after correct installation
• refill pack format helps replenish inserts without duplicating tools already available in the workshop

• 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.

1. Compare M 18 x 1.5 and 9.0 mm with the repair specification before opening the refill pack.
2. Remove damaged thread material using the preparation tools specified for the repair system.
3. Create the STI receiving thread with the matching repair tap.
4. Clean the bore and thread flanks before the insert is installed.
5. Install the wire insert to the specified seating position using the correct tool.
6. Remove installation remnants where the process requires that action.
7. Verify that the mating screw starts smoothly and reaches the required engagement.

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.
