Another case of the owner of an Audi A6. He chose a set of navy blue BONOSS shell bolts. This bolt is a short shell. BONOSS sells long and short bolts. The difference between the two products is that their length of the shell. The material is still the same material and style in terms of screws, and four anti-theft bolts are still provided to protect the owner’s car. In most cases, when a car owner chooses to replace a new set of wheels, he will choose a set of suitable wheel bolts. The reason is that the bolt contact surface of the modified wheel is not necessarily the same as the original car, cone, spherical, or even flat. , BONOSS provides modified hub bolts with conical and spherical surfaces to fit the hub contact surface on the market.
