This crown wheel bolt is intended for installation in the drivetrain of a classic mid‑size saloon type vehicle. The bolt uses metric thread with a diameter of ten millimetres and a length of twenty‑six millimetres. The head is shaped for use with a matching wrench and washer. The bolt secures the crown wheel to the differential case and transfers torque and load from engine and gearbox. The material is selected for mechanical load in normal road operation. Suitable for maintenance, overhaul or replacement of existing fixing hardware in the final drive assembly.
