Specifications
• X9- ASTM Equivalent: A354 Grade BD
The Conquest Grade 8 Indented Flange Bolt is built for jobs where failure isn’t an option. Engineered for maximum tensile strength and durability, this bolt is a go-to solution across high-load applications in construction, manufacturing, and heavy equipment maintenance. Whether you're fastening structural steel, securing large assemblies, or replacing OEM hardware, these flange bolts bring the heat, no washers needed.
Manufactured from premium-grade alloy steel and designed with a built-in indented flange, each bolt distributes load more evenly while minimizing surface damage. That means fewer parts, faster installs, and less hassle. The plain finish keeps it cost-effective for interior and controlled environments where corrosion isn’t a primary concern.
Available in multiple diameters and lengths, this bolt line is built to match your specs and your schedule.
Key Features:
- Grade 8 Alloy Steel: Delivers high tensile strength and load resistance for demanding applications.
- Indented Flange Head: Acts like a built-in washer, spreading load evenly and reducing the need for extra hardware.
- Plain Finish: Ideal for indoor or low-exposure environments where coating isn’t required.
- Threaded Shank Options: Choose from a variety of lengths and diameters to match your project’s needs.
- Precision Machined Threads: For smooth engagement and secure clamping force.
Common Applications:
- Structural steel connections
- Agricultural and heavy-duty equipment
- Automotive frame assembly
- Industrial machinery repair
- OEM part replacement
Installation Tips:
- Use with matching Grade 8 nuts for optimal strength.
- Torque according to ASTM A354 or SAE J429 specs to avoid over-tightening.
- Ensure threads are clean and properly aligned to prevent stripping.

I couldn't find these bolts anywhere else and Fasteners Plus was the only one that had them. I checked all the go to places like Home Depot, Lowe's, local hardware stores but nobody had this size so thank you fasteners plus.
Great product and even better customer support. We had an issue with our order and customer service had it corrected and had our bolts to us the very next day! Highly recommended
It’s all good. Fasteners that are not typical,,,, buy the quantity you specify. Sure it can be pricey. Way better than driving and researching everywhere. Load up on some quality products and relax.
I needed 16 bolts of a certain thread and size which I could only find at fasteners plus. This little purchase was unbelievably expensive due to shipping and handling.

The bolts are exactly what I was looking for. The ones I recieved are perfect but I'm still waiting for a missing bolt. I was sent 9 that I chose and one incorrect bolt. I wrote to customer servive and was told the last bolt is on it's way.
