Review on 🔩 Heli-Coil M12X1.25 Metric Kit with 554312 Compatibility by Reginald Hamilton

I purchased this thread repair kit for an aluminum engine block. I removed the block and placed it on the stand. I used a metric tap to tap out the threads, but unfortunately the tap was inaccurate and the threads became too loose as a result. This kit installed without any problems and restored the block to a usable condition. This is exactly what I needed!
