5/8" x 2-1/4" 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

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!
