1/4" x 3" 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 1/4" Conquest Grade 8 Non‑Serrated Flange Bolt with a zinc yellow finish is engineered for serious strength and long-term durability. Built from high-tensile alloy steel and finished in corrosion-resistant zinc yellow, it's ideal for structural, mechanical, or chassis applications where clean installation and surface protection are critical.
Flange Head Strength Without the Surface Damage
This flange bolt features a built-in washer-style head that distributes load evenly, reducing the need for additional hardware and minimizing stress on contact surfaces. The non-serrated design protects painted or precision parts from gouging during installation. Designed to SAE J429 Grade 8 and ASTM A354 Grade BD equivalency for performance under high-stress and vibration conditions.
Key Features
- Grade 8 Alloy Steel: Built for strength and stress-resistance in critical fastening applications.
- Zinc Yellow Finish: Corrosion-resistant and ideal for high-visibility or professional finish requirements.
- Non-Serrated Flange Head: Eliminates the need for washers while protecting contact surfaces.
- Thread Profile: 20 threads per inch with coarse threading for strong, quick engagement.
- Multiple Size Options: Available in a variety of diameters and lengths to suit your project.
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

Customer Reviews
I have a show engine in my 68 Camaro, so I am particular about the bolts I choose to use. Many of the factory spec bolts are boring, and replacements are hard to replicate. These guys made bolts that were perfect for my application, and I will be reaching out to them in the future as my work progresses.
These bolts came real quick and they are just what I needed for my project
Exactly what I ordered and delivered within a few days of placing the order!
