Description

5/8" x 2" Conquest Grade 8 Non-Serrated Flange Bolt With Yellow Zinc Finish

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

Engineered for strength and precision, the 5/8" Conquest Grade 8 Non-Serrated Flange Bolt offers heavy-duty performance for critical assemblies. The zinc yellow finish enhances corrosion resistance while delivering a clean, professional look. Built from Grade 8 alloy steel, this bolt withstands high tensile loads in demanding industrial, construction, and automotive applications.

Torque-Ready Strength with Surface Protection

The integrated flange acts like a washer, distributing load and clamping pressure evenly, while the non-serrated underside ensures minimal wear on mating surfaces. This makes it ideal for slotted holes and applications where surface integrity must be preserved.

Key Features

  • Grade 8 Steel: Delivers superior strength for load-critical environments.
  • Zinc Yellow Finish: Corrosion-resistant with a sharp, professional appearance.
  • Non-Serrated Flange Head: Prevents damage to mounting surfaces and components.
  • Flange Design: Distributes force evenly, eliminating the need for a separate washer.
  • Thread Specification: Coarse thread, 11 TPI (threads per inch).

Common Applications

  • Structural steel framing and fabrication in construction or industrial settings
  • Heavy equipment assembly including loaders, lifts, and mechanical arms
  • Automotive chassis, suspension systems, and drivetrain components
  • Agricultural and industrial machinery installations
  • High-load bolting where vibration resistance and surface protection are critical

Installation Tips

  • Torque bolts to SAE J429 specifications to ensure proper preload and bolt performance
  • Use with Grade 8 nuts and hardened washers to maintain full tensile strength and load distribution
  • Avoid overtightening to protect mating surfaces, especially in slotted holes or precision applications
  • Inspect flange seating for flush contact to prevent loosening under vibration
  • Verify the bolt length provides full thread engagement without bottoming out
