Description
Product Overview
The SUCOSO 17mm Hex Lug Bolt is a precision‑engineered fastener designed to meet the demanding requirements of modern automotive wheels. Crafted from high‑strength 40Cr alloy steel, each bolt undergoes a rigorous cold‑forging process that enhances its tensile strength and fatigue resistance. The black electrophoretic coating not only gives the bolt a sleek, glossy appearance but also creates a protective barrier against moisture, road salts, and harsh environmental conditions, significantly reducing the risk of rust and corrosion over time.
With a hex head size of 17mm and a thread specification of M12 x 1.5, these bolts provide a perfect match for a wide range of vehicle models, including BMW, Mercedes‑Benz, and select Jeep and Chevrolet platforms. The fully threaded shank ensures even load distribution across the wheel hub, while the 60‑degree conical seat offers a secure, vibration‑free connection that maintains wheel alignment and balance even under aggressive driving conditions.

Usage
These lug bolts are ideal for both original equipment installations and aftermarket upgrades. Whether you are replacing worn‑out OEM nuts, performing a wheel refurbishment, or customizing your vehicle for track use, the SUCOSO lug bolt delivers reliable performance. The design accommodates rear‑wheel drive and all‑wheel drive configurations, making it suitable for daily commuters, performance enthusiasts, and off‑road adventurers alike. Installation is straightforward with standard 17mm socket tools, and the bolts are compatible with most torque specifications recommended by vehicle manufacturers.
Because the bolt length (49mm) and shank length (23.5mm) mirror OEM dimensions, there is no need for additional spacers or adjustments. This ensures a seamless fit on wheels that require a 12 mm groove diameter, providing a clean, professional finish without compromising safety or handling.

FAQ
What vehicles are compatible with these lug bolts?
The 17mm hex design with M12 × 1.5 thread fits a range of BMW models from the early 1990s through 2013, as well as select Mercedes‑Benz, Jeep Cherokee, and Chevrolet Renegade wheels that use a 12 mm groove diameter. Always verify your wheel’s bolt pattern before purchase.
Can I use these bolts on alloy wheels?
Yes. The bolts are engineered for both steel and alloy wheel applications. The black coating helps prevent galvanic corrosion when paired with aluminum alloy wheels, extending the life of both the fastener and the wheel.
Do I need any special tools to install the bolts?
No special tools are required. A standard 17mm socket or wrench will fit the hex head perfectly. Follow the vehicle manufacturer’s torque specifications, typically between 80‑100 Nm, to ensure proper clamping force.
What warranty does SUCOSO provide?
SUCOSO offers a limited one‑year warranty covering material defects and manufacturing flaws. If a bolt fails due to a defect within the warranty period, we will replace it at no additional cost.
