Description

The Conquest Grade 8 Non-Serrated Fine Thread Flange Bolt in Zinc Yellow is engineered for applications where strength, precision, and corrosion resistance matter. Whether you're assembling heavy machinery, reinforcing structural connections, or tackling demanding automotive repairs, this bolt delivers unwavering performance under pressure.

Manufactured from premium-grade steel and finished with a Zinc Yellow coating, this bolt resists rust and wear in tough environments. The integrated washer-style flange head distributes load evenly, reducing the need for a separate washer and increasing torque control. Its fine-thread design ensures a tighter grip and improved resistance to loosening from vibration—perfect for dynamic load conditions and high-stress assemblies.

Offered in a range of diameters and lengths, this bolt gives you the flexibility to match your specific build or repair requirement. Installation is simple with standard hand tools or impact drivers—just match the thread and torque specs to your project needs.

Key Features:

  • Grade 8 Strength: Meets high-performance mechanical requirements with outstanding tensile strength.
  • Non-Serrated Flange Head: Built-in washer helps spread load and provides consistent clamping without damaging mating surfaces.
  • Fine Thread Design: Enhances holding power and is ideal for applications requiring higher pre-load and tension retention.
  • Zinc Yellow Plated Finish: Provides moderate corrosion resistance and a clean, professional appearance.
  • Available Options: Choose from a variety of diameters and lengths to suit light- to heavy-duty installations.

Common Applications:

  • Automotive and engine assemblies
  • Agricultural equipment
  • Heavy-duty trailers and chassis construction
  • Structural frameworks
  • Machinery repairs

Installation Tips:

  • Use a calibrated torque wrench for precision tightening.
  • Always match the fine thread pitch to the mating component to prevent cross-threading.
  • For critical applications, apply threadlocker or follow manufacturer torque specs to ensure optimal joint security.
