Core Features of Hexagon Socket Head Cap Bolt with Serration
- Hexagon socket head design: Enables high-torque transmission, suitable for installation in narrow or recessed spaces, with a compact and aesthetic appearance
- Serrated under head feature: Sharp serrations on the bolt head bottom bite into the workpiece surface during tightening, preventing bolt rotation and enhancing anti-loosening performance, especially effective in high-vibration environments
- Excellent load-bearing capacity and shear strength, ensuring stable connection under long-term use
- Corrosion resistance: Surface treatments (e.g., zinc plating, nickel plating, blackening) or stainless steel materials adapt to indoor, outdoor, and harsh working conditions
