Quanzhou Zhongke Autoparts — Trusted Supplier of High-Performance Center Bolts

Product Description

Center bolts are designed to clamp together the leaves in a spring pack and keep them centered on the axle, providing stability to the suspension system. Despite their small size, they play a critical role in preventing lateral movement of the spring leaves and maintaining vehicle balance and driving safety. If a center bolt fails, the spring may become misaligned, leading to dangerous handling characteristics and premature wear.

At Zhongke, our center bolts are manufactured using high-quality materials such as 45# carbon steel and 40Cr alloy steel, known for their superior tensile strength and resistance to fatigue. Our production process includes precise machining, heat treatment, and advanced surface finishes—such as zinc plating, black oxide, phosphating, and electrophoresis—to ensure durability and long-term corrosion resistance.

We offer full customization in dimensions, thread pitch, and finish to suit different vehicle models and suspension configurations. Our center bolts are widely used by OEMs and aftermarket customers across global markets. Each product undergoes strict quality inspection to guarantee consistent performance and compliance with international standards.
