Conquest Grade 8 Non-Serrated Flange Bolt – Zinc Yellow
Built for strength. Designed for efficiency. The Conquest Grade 8 Non-Serrated Flange Bolt in a zinc yellow finish is engineered to hold tight under pressure. Whether you're securing structural assemblies, heavy-duty machinery, or automotive frames, this bolt is built to meet the moment.
Made from high-strength Grade 8 steel, it delivers superior tensile strength for high-load applications. The zinc yellow coating provides excellent corrosion resistance and a clean, professional finish. The built-in flange acts like a washer, spreading out the load and helping reduce the chance of damaging surfaces.
With no serrations under the head, it’s ideal for use where surface damage must be avoided or when used in slotted holes. It's a reliable choice when paired with hardened washers or precision fittings.
Features:
- Grade 8 Strength – Manufactured for critical applications requiring high tensile performance and reliability.
- Zinc Yellow Finish – Provides corrosion resistance while delivering a sharp, professional look.
- Flange Head Design – Built-in flange distributes clamping force evenly, eliminating the need for a separate washer.
- Non-Serrated Head – Safe for use on precision surfaces or components that require minimal marring.
- Available in Multiple Sizes – Choose the diameter and length that best fits your project requirements.
Applications:
- Structural steel fabrication
- Heavy equipment assembly
- Automotive chassis and suspension
- Agricultural and industrial machinery
- Construction and repair projects where vibration resistance matters
