Well it's gonna be metric.
My guess is a 15mm 14mm 13mm 12mm
The thread is gonna be 8mm.
Not gonna be bigger, nor smaller than that. [sleep]

 

Torx 50

 

Yes. My bad for just spouting off. Yesterday i happened to LOOK at the bolt holding the back of the seat and oops. Torx. Definitly a Torx. So I apologize for being a know it all. [bash]

 

I used a T45 last night to remove one in my '12. Not sure if it was the correct size or not, but it worked.

 

Be careful, one of these days you'll come across something that you'll strip by using the wrong size tool for the job. [thumb]

 

Thanks guys for your help....It was a T50.

 

Does anyone know the size of the rear seat frame bolts on 2012 hatchback SE
