GB4231 U-Bolt

The GB4231 U-Bolt is a standardized fastener compliant with China's national specifications, engineered to secure cylindrical or tubular components in demanding environments. Widely used in automotive systems, such as heavy-duty truck chassis and commercial vehicle suspension systems, its U-shaped design ensures robust clamping force to withstand vibrations, shocks, and dynamic loads. Constructed from carbon steel or alloy steel, it undergoes surface treatments like zinc plating or Dacromet coating to resist corrosion and abrasion, making it ideal for harsh conditions like salt spray or humidity.

The GB4231 U-Bolt features calibrated threading and a radius-optimized U-bend, minimizing stress concentration and metal fatigue—critical for automotive parts exposed to constant motion. In commercial vehicles, it is integral to fixing rear axle leaf springs, directly impacting load-bearing safety and stability. Standardized dimensions ensure compatibility with OEM components, while customizable options (diameter, length, coating) address specialized automotive aftermarket needs.
