How Can Serrated Stainless Steel Bolts Prevent Loosening in High-Vibration Automotive Applications?

Our 430 SS bolts with serration under head provide superior anti-loosening performance in high-vibration environments. The precision-engineered serrations create increased friction and load distribution, while the grip gaging body ensures consistent torque application. Each bolt is ISO-inspected using 2.5D projectors to verify serration diameter and depth, guaranteeing reliable performance in critical automotive assemblies. Contact us for custom specifications tailored to your vibration-resistant fastening requirements.
