I got the M6/7x29.5 bolt that I broke above. Now what I realise next is that the bolt side M7 that goes into the engine side would not tighten, once it is fully screwed in, it just keeps rotating seems like the threads are gone or lose or something (but if I try to pull the bolt it does not comes out). I did some finding and it appears that I need helicoils. Does any one know if following is that I need?

Part number 07 14 6 958 587

Otherwise, for M7 bolt, would I need a 7mm helicoil or a 8mm helicoil. Also, what is the thread size on the bolt M6/7x29.5 bolt, 1mm or 1.?? mm or 0.?? mm

For further details, the bolt with part number: 11121718856 is going into the engine assembly and is free i.e. the thread on the female part which is in the engine assembly needs repairing for which I need helicoils. But what size of helicoil is what I need to know.
