### ⭐⭐⭐⭐⭐ M12 Inserts
*by J***5 on 14 January 2024*

These are excellent I had an injector hold down bolt hole and the thread had stripped a helicoil kept failing within minutes of being started. These are solid and hold the injector bolt down perfectly probably stronger than the original thread! Don’t waste time and money on helicoils use these very easy to fit and right for the job very pleased!
