Advice needed for thread inserts

Recommended Posts

I turned up an aluminum adapter to join a bmw driveshaft to the r200 diff, I'm worried about the soft metal threads and not being able to torque the M8 bolts on the diff side. I can't mount a fixed stud because there would not be enough room to install, can't use nuts to sandwich the flange.

I may have to remake the adapter in steel but want to try and make this work first if I can.

So I'm thinking some kind of Helicoil or maybe an interference fit threaded insert.

Would appreciate any advice,

thanks,

Chris

Timesert kit arrived, very impressed, well thought out. I think it is going to do the trick.

I ordered the 16.2mm long inserts so I could use the full thickness of the flange
