V-COIL Wire Thread Inserts M 2.5 x 0.45, Refill Pack | 40204
Reliable refill for M2.5 thread repair work
In maintenance, assembly and service workshops, small threads can decide whether a component stays in operation. When an M2.5 internal thread is damaged or worn, this refill pack provides the inserts you need to restore a clean, functional thread – as a practical addition to an existing V-COIL setup.
The Type S free running inserts are designed for consistent results in fine-thread repair and for thread reinforcement (thread armour plating) in base materials with low shear strength. This makes the pack a solid option for mechanical engineering, metalworking and repair departments aiming to rework parts and reduce scrap.
Made from stainless steel to DIN 8140 with 1.0D length, the inserts fit compact components and applications with limited installation depth. The practical Self Service Hanging packaging (up to M12) supports tidy storage and quick access in day-to-day work.

- Thread repair: repair damaged or worn-out internal threads.
- Thread armour plating: reinforce threads in materials with low shear strength.
- Recovery of rejected items: rework parts affected by drilling or threading errors.

What does “free running” mean?
The insert does not apply a locking effect. The screw can be installed and removed normally after repair.
Why use inserts for reinforcement?
Inserts can improve load distribution and reduce wear, especially in materials with low shear strength.
Can I use these inserts with a different pitch?
No. These inserts are designed specifically for M 2.5 x 0.45.
