Product Features & Technical Specifications
- Material Excellence: Made from C1022A carbon steel for high strength and hardness, ensuring the screw can penetrate tough materials without deformation.
- Ruspert Coating: A multi-layer anti-corrosion system that provides up to 20 times longer life than regular zinc plating, ideal for outdoor or humid environments.
- Hex Head Design: Standard hex head allows for secure socket or wrench installation, reducing cam-out and slippage during high-torque driving.
