BONOSS Forged Grade 12.9 Shell Type Lock Wheel Bolts (Metal Gray) for Mercedes-Benz AMG CLA 45 (3)

Excellent upgrade! Last Monday, this Mercedes-Benz AMG CLA 45 installed BONOSS Forged Grade 12.9 Shell Type Lock Wheel Bolts (Metal Gray), M14x1.5 with a conical seat to fit the new 19-inch RAYS G025 wheels, PCD 5×112, CB 66.6. The CLA-Class is popular among many young car enthusiasts. It is often modified by private teams or the factory for racing, stance show, or just street rides. Larger-size wheels can enhance steering experience and high-speed performance. Increasing wheel diameter generally means wider tire width as well, body control tends to get sharper, and handling usually improves too. By installing new style bolts, you can also make the vehicle look excellent, personalized, and different. (Thanks VENENO for providing these pics.)

Within the car marketplace, the Mercedes-Benz AMG CLA 45 can be the most successful selling street coupes on the planet. It boots with an AMG 2.0L inline-4 turbo engine, which provides excellent and cheerful acceleration performance, and an 8-speed dual-clutch automatic transmission, offering an engaging and sharp switch. The steering is precise, and the road holding is reasonable. According to the test, the model accelerates to 60mph in as little as 4 seconds. It is such an amazing car, after proper modifications, it becomes more powerful, stylish, and gorgeous.

Advantages of BONOSS Forged Grade 12.9 Shell Type Lock Wheel Bolts

Since they are relatively small parts under extremely large forces, and they are absolutely critical to holding the wheel on your customer’s vehicle, the material is quite important. BONOSS shell bolts applied Japanese Standard SCM440 steel material, which features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance, and high-temperature resistance. The shell applied forged 7075-T6 Aluminum alloy for high-strength and excellent toughness meanwhile maintain lightweight for extreme performance improvement.

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 to defend criminals from stealing your wheels.

Important Concerns for Lug Bolts Installation

The lug bolts need to be installed correctly, and they also must be properly torqued to manufacturer-recommended torque specs. This means making sure the wheel and hub are secured enough to where they don’t get loose. Untightened lug bolts (the clamping force is not enough) or overtightened lug bolts (the bolt has been stretched past its tensile strength limit, so the clamping force has gone away) will cause most lug bolt failures. Find a suitable balance in the level of tightness and the bolt will remain strong, providing the greatest possible force to lock the wheel to the hub. This ensures safe driving.
