3/8″ x 1″ 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.

The 3/8″ Conquest Grade 8 Non-Serrated Flange Bolt is engineered for strength and precision. Constructed from Grade 8 alloy steel and coated in a corrosion-resistant zinc yellow finish, this flange bolt is built for high-load industrial, automotive, and structural applications.

Built-In Flange. Surface-Safe. Reliable Under Load.

Its integrated flange spreads out clamping force, reducing the need for washers while protecting against material damage. With a non-serrated design under the head, its the go-to option for applications where surface marring is not acceptable or where bolts are seated in slotted holes.

Key Features

• Grade 8 Alloy Steel: Maximum strength for critical fastening tasks.
• Zinc Yellow Finish: Protects against corrosion while providing a clean, finished appearance.
• Flange Head Design: Distributes load evenly, minimizing the risk of surface damage.
• Non-Serrated Head: Ideal for use on painted, finished, or sensitive materials.
• Thread Spec: Coarse thread, 16 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
