Setup, Compatibility & Care
Setup:
- Ensure the vehicle is safely supported on a jack stand before attempting to remove or install any wheel bolts.
- Clean the wheel hub threads and the bolt hole on the wheel to remove any debris or old thread locker.
- Insert the wheel bolt and thread it in by hand to ensure it's not cross-threaded.
- Tighten the bolt gradually in a star pattern using a 19mm wrench or socket to the manufacturer's specified torque. Do not overtighten.
Compatibility:
This wheel bolt is designed with specific dimensions (M12 x 1.25 external thread, 22mm thread length, 19mm hex width, conical seat) for use with steel rims on various FIAT, Alfa Romeo, and Lancia models, including FIAT Punto I, Alfa Romeo 156, and Lancia Y (840A). Always consult the vehicle's owner manual or a reputable parts finder, such as the Bilstein group partsfinder, to confirm exact compatibility with your vehicle's year, model, and wheel type. Verify that the OE numbers (e.g., Alfa Romeo: 13230024, FIAT: 13230024) match your vehicle's requirements. This bolt is intended for steel rims only.
Care:
Keep the wheel bolts clean and free from dirt, grease, and corrosion. Periodically inspect them for any signs of damage, such as stripped threads or cracks. If corrosion becomes apparent, a gentle cleaning with a wire brush can help, followed by a light application of an anti-seize compound if recommended by the vehicle manufacturer (though often not required for original bolts). Ensure bolts are torqued correctly after installation and re-checked after a short driving distance (e.g., 50-100 km).
