Grade 5 Strength

• Medium carbon steel construction
• Stronger than standard hardware bolts
• Suitable for light structural and mounting applications

👉 Provides reliable clamping force without overloading smaller components.

Hex Head Design

• Standard hex head for easy installation
• Allows proper torque application
• Compatible with common tools

Zinc-Plated Finish

• Sacrificial corrosion protection
• Helps protect base metal and surrounding components
• Consistent with OEM trailer hardware systems

👉 Zinc is designed to wear first, protecting the trailer over time.

Fitment & Specifications
