1/2″ x 2-1/2″ 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.
The Conquest 1/2″ Grade 8 NonSerrated Flange Bolt in zinc yellow deliver superior tensile strength and corrosion resistance for demanding applications. Made from highstrength Grade 8 steel with a vibrant zinc yellow finish, this bolt is engineered to hold tight under pressure and resist corrosion in industrial, automotive, and structural assemblies.
HeavyDuty Clamping Force with a Clean, NonSerrated Flange Head
Featuring a builtin flange that distributes load evenly and a nonserrated head to protect precision surfaces, this bolt eliminates the need for a separate washer while protecting mating components. The coarse 13 TPI thread profile and Grade 8 construction make it ideal for highstress, vibrationprone environments.
Key Features
- Grade 8 Strength: Built to SAE J429 / X9ASTM A354 Grade BD equivalent standards for high tensile performance.
- Zinc Yellow Finish: Provides excellent corrosion resistance and a professional, finished look.
- Flange Head Design: Distributes clamping force evenly across surfaces without a separate washer.
- NonSerrated Surface: Ideal for use on precision or painted surfaces where marring must be avoided.
- Coarse Thread (13 TPI): Engineered for strong engagement and easy assembly.
- Versatile Sizes Available: Choose the diameter and length that fit your job requirements.
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
