Does anyone know the tap size for a 7/16-20 helicoil insert? I bought a used kit on EBay and the tap in it is not the correct size.
I have the hole drilled out to 29/64, as called out in the directions.
I'm afraid it's not a normal thread size, and there for a special tap is required - at a cost i'm sure I won't like.
