This heavy-duty hardware is used to securely fasten and clamp the wheel bearing/hub assembly to the steering knuckle (spindle).
Specifications
Thread / Dimensions: M12 x 1.5 x 46 mm (Note: Depending on the catalog, the thread pitch is occasionally listed as M12x1.25, but it is an M12 bolt with a 46mm shank length).
Material Type: High-tensile strength automotive fastener.
Important Installation Note
Single-Use Hardware: This is a torque-to-yield (stretch) bolt. Factory service manuals dictate that this part cannot be reused or reinstalled.
Once loosened or removed during a wheel bearing replacement or suspension teardown, it loses its required clamping elasticity and must be replaced with a new bolt to ensure driving safety.
