AUTOPTIM M12x1.5 OEM Lug Nuts - 20 Chrome One-Piece, Radius Seat for Honda/Acura

AUTOPTIM M12x1.5 OEM lug nuts are a set of 20 chrome, one-piece replacement nuts engineered to fit many Honda and Acura factory-style wheels with M12 x 1.5 threads.

Before ordering, confirm your wheel’s seat type and the bolt pattern to ensure compatibility.
