This bolt is used to fasten the starter ring gear on a specific passenger car model. Its dimensions support firm centering of the ring gear on the flywheel. Head design and shank length allow installation in the prepared holes of the assembly. The material suits the mechanical load typical of the starting system. The bolt works together with other fasteners to create a stable connection. The fit helps prevent play between ring gear and flywheel. This component serves as a replacement fastening element during maintenance or restoration of the vehicle starting and drive system.
