Review on HelicoilR1084 6 Helical Insert 304SS M6X1 by Tony Wylie

I bought this for my car had the bolt holes in the valve cover cleaned. It was enough for me to drill all the bolt holes, the head was already installed, with the help of magnets and a workshop vacuum cleaner I was able to restore almost every crumb of metal after drilling and thread cutting. The spools were slightly longer, which is a good thing, than the ones that came with the threading kit I bought. Saved me from removing the head and contacting a car service. Pulled his ass out of the sling. I will definitely buy it again if the need arises and would highly recommend it to others.
