Chassis Bolt
Product Description
Chassis bolts are vital components used to fasten structural parts in the undercarriage of heavy-duty trucks. These bolts are specifically engineered to provide reliable, long-lasting connections that can withstand high vibration, impact, and heavy loading under extreme road and weather conditions.
At Zhongke, we produce chassis bolts using superior alloy steel materials such as 40Cr, 35CrMo, and 45#, ensuring exceptional tensile strength, wear resistance, and fatigue durability. We apply precision cold or hot forging processes and incorporate advanced heat treatment techniques to enhance performance and mechanical stability.
Surface finishes such as black oxide, zinc plating, and Dacromet are used to improve corrosion resistance and extend product life in various working environments.
Available in a wide range of diameters and thread pitches, our chassis bolts can also be custom-engineered based on technical drawings or customer specifications. Every bolt undergoes stringent quality inspection prior to delivery to guarantee safety and performance.
