1/4" x 1" Conquest Grade 8 Indented Flange Bolt
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 Indented Flange Bolt is engineered for strength and reliability in demanding fastening applications. Manufactured from premium Grade 8 alloy steel with a precision‑machined coarse thread (20 TPI), this bolt delivers superior tensile performance for structural assemblies, machinery, and heavy equipment repair. The integrated indented flange distributes load evenly while minimizing surface damage, so you can install with fewer components and less hassle.
Built‑In Load Distribution and High‑Strength Performance
This flange bolt is designed for applications where secure clamping and material integrity are essential. Its plain finish makes it cost‑effective and ideal for interior or controlled environments where corrosion protection isn’t required. Pair with matching Grade 8 nuts for maximum performance and reliability.
Key Features
- Grade 8 Alloy Steel: Superior tensile strength for heavy‑load and critical applications.
- Indented Flange Head: Acts like an integrated washer to distribute load evenly and reduce hardware count.
- Plain Finish: Cost‑effective solution for indoor or low‑exposure jobs.
- Coarse Thread (20 TPI): Provides secure engagement and smooth installation.
- Precision Machined Threads: Ensures secure clamp force without thread binding.
Common Applications
- Structural steel bolting in commercial and industrial construction
- Assembly and maintenance of agricultural and heavy-duty machinery
- Automotive frame, suspension, and chassis installations
- Industrial machinery builds and repairs requiring high-strength fastening
- OEM hardware replacement in equipment where tensile reliability is critical
Installation Tips
- Always use with matching Grade 8 nuts to maintain load capacity and thread compatibility
- Torque to spec per ASTM A354 or SAE J429 guidelines to prevent thread damage or bolt failure
- Inspect threads before installation; clean and align properly to ensure smooth engagement
- Do not overtighten, built-in flange provides proper load distribution without additional washers
- Use in dry, protected environments to maximize bolt lifespan with plain finish

I use flange bolts for almost every application. The additional clamping power and not digging into softer metals.
Well, this is the first time I really has ever ordered boats online and it was such an easy process through this company that I wouldn’t go. Any anywhere else to purchase anything but right here. Thank you for such a well organized and customer oriented company.
Great prices! My go to place for bolts etc.
