## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by L***E on September 22, 2025*

The former owner of my 2009 Nissan Versa had welded the oxygen sensor in. After removing the old sensor and welding, I used the helicoil to replace the thread. It was easy to insert the product and to put the new sensor in.

### ⭐⭐⭐⭐⭐ Works well
*by M***B on November 16, 2025*

Good product.

### ⭐⭐⭐⭐⭐ Saved a few parts from the trash
*by J***Z on August 8, 2025*

Used these M3×0.5 (1D) coils to fix stripped threads on an aluminum bracket and a 3D-printer part. The coils are consistent, no burrs, and standard M3 screws run in smooth with zero wobble. Tangs snapped cleanly with a punch. Once installed, the threads feel stronger than the originals. Tips: you’ll need the proper M3×0.5 STI tap and about a 3.2 mm drill. A dab of blue Loctite on the outside of the coil keeps it put. 1D length is perfect for shallow holes; if you need more engagement, look for 1.5D/2D.
