With the exciting release of the new 2022 W206-generation C300 Sedan, BONOSS keeps up with the trend, designs, and manufactures high-quality lug wheel bolts with a stylish exterior for building your new car Safely and Wonderfully. One of the simplest and most efficient modifications is to replace a set of new wheels. Custom aftermarket wheels can not only add a personalized style but also enhance the handling performance of your vehicle. Therefore, when changing wheels, you can choose some non-original wheels according to your needs.
Although many aftermarket alloy rims are designed to use your car’s stock lug nuts or wheel bolts, there are others that require new hardware. It can be something as central as the differences in the rim’s lug seat type, or something as simple as shorter heads of the lug bolts to fit the wheel’s center caps. Wheel bolts are relatively small components under extremely large forces, and they are absolutely critical to locking the wheel on your vehicle so that the seat type and other fitment are quite important.
BONOSS Forged Grade 12.9 Lug Wheel Bolts
BONOSS Forged Grade 12.9 Lug Wheel Bolts are made by the forged process. The forging process offers lots of advantages over other manufacturing processes for wheel bolts. Due to the continuous intense pressure extrusion, the forging process brings superior mechanical and physical properties. Among the key advantages 
are:
- High tensile strength and tough, safe and secure
- Hard and durable, guarantee long-term applications
- Better wear resistance and higher fatigue strength
- Elimination of porosity, evenly and tight internal structure
- Good polishing and finishing surface characteristics
The head part of BONOSS Lug Bolts is Twelve Petals Shape. This design is not only for aesthetic purposes, but more importantly, it is a proof of super forging process (The edges and corners of the petal shape can only be manufactured by forging process, and such a uniform distribution requires a large-tonnage machine in one-time forming, which cannot be presented in a later turning process).
BONOSS Forged Grade 12.9 Shell Type Lock Wheel Bolts
BONOSS is proud to announce the release of an all-new racing lug bolt. It’s called BONOSS Forged Grade 12.9 Shell Type Lock Wheel Bolt. We upgrade the exterior of traditional lug bolts, matching the bolt with a shell for protecting the bolts from debris and water corrosion and maximally beautifying your wheels. We know these wheels are very valuable for you. This is why we have designed these lock bolts with an irregular outer diameter shape head which requires a special key tool to loosen and remove. They come with an anti-theft function for protecting your finest wheels. Even if the thieves have a full set of socket wrenches, they won’t have the unique shape socket to fit. This effectively decreases the stolen risk of your wheels. The only time the wheel lug bolts can be removed is when the key socket with the correct pattern is inserted. Besides, various colors are available for your preference.
How to Confirm the Seat Type of Bolts for Your New Wheels?
There are conical seats (also called “cone” or “tapered” seats), ball seats (also called “radius” or “rounded” seats), flat seats (also called “mag” seats), etc. A 60° Conical Seat is the most common and is found on most aftermarket wheels. But there may be differences, so please take a check to your new rims. You can get information from the wheel manufacturers or just touch the lug seat around directly with your fingers. Typically, for the factory wheels, the seat type of the lug bolts will be the same as the factory wheel bolts. For the aftermarket wheels, the seat type of the lug bolts must be the same as the type of the aftermarket wheels. It is essential that the wheel bolts seat and the wheel lug seat match. If the wheel bolts seat type does not fit the wheel lug seat type, it is possible that the wheel bolts would be bent or damage the wheel. The mismatch between bolts and wheels could potentially cause the bolt to loosen and the wheel to become insecure to the vehicle.
Premium Material for Higher Performance
BONOSS Forged Grade 12.9 Wheel Bolts applied JIS SCM440 steel material. The SCM440 is a medium carbon chromium molybdenum alloy steel. The Chromium provides good hardness permeability and Molybdenum gives hardness uniformity and high strength. It also has good ductility and high-temperature stress resistance, structural stability, low harmful elements, a small decarburization layer, few surface defects, and more advantages. Wheel Bolts made of Forged SCM440 alloy steel features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance, and high-temperature resistance. The shell of BONOSS Shell Type Lock Bolts applied forged 7075-T6 Aluminum alloy for high-strength and excellent toughness meanwhile maintain lightweight for extreme performance improvement.
BONOSS offers a full line of wheel bolts to suit your new wheels. They are engineered in different lengths to match many vehicles. All BONOSS Wheel Bolts are manufacturing in the OEM factory and backed by thousands of successful solution experiences. We’re up to date on various thread sizes as well – M14x1.5, M14x1.25, M12x1.5, M12x1.25 and M15x1.25, 1/2-20 UNF so that we can provide wheel bolts for most vehicle models in the market.
