Bent inner steel threads

​

I got a Bosch ebike and use top quality inner threads and a steel bolt to connect the cranks. Its 60nm

I used a wrong tool to try and get of the cranks. A few swear words and huffs later I realized I have bent the 1st starting thread.

I used the wrong crank remover and used some force and pushed the 1st thread in.

I was mad and panicking at the same time and quit the job and decided to tighten it all back together.

I put the bolt in feel resistance and keep going till 60nm. These inner threads r very strong. I didn't cross thread just felt resistance. Hasn't loosened in 1500 miles under extreme pedalling force 75nm and 600 watts.

I want to take it back off but I obviously thinks it might be absolutely mangled the threads or I might off fixed the bent thread.

Only 1 thread is bent the very start. I been googling this. But the obvious answer is I'll only know if I take it off?

Do u think the steel bolt might of fixed the bent inner thread or ruined other threads? This is a £2k bike no bike shop will touch a Bosch motor.

I want to loosen the steel bolt change a part and tighten it with the 1st inner thread bent
