3/8" x 1-3/4" 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 3/8" Conquest Grade 8 Indented Flange Bolt is a high-performance fastener designed for serious structural and mechanical applications. Precision-engineered from tough Grade 8 alloy steel, it offers exceptional tensile strength and durability where reliability is non-negotiable.
Flange Bolts for Structural Connections
This bolt features an integrated indented flange head that acts as a built-in washer, distributing clamping force more evenly and reducing the need for additional hardware. The plain finish offers a cost-effective option for indoor or low-exposure environments, where corrosion resistance isn’t critical.
Key Features
- Grade 8 Alloy Steel: Provides superior tensile and yield strength for high-load demands.
- Indented Flange Head: Expands the load area, reducing surface damage and eliminating washer needs.
- Plain Finish: Ideal for interior use or protected installations where coating isn’t necessary.
- Coarse Thread (16 TPI): Enables quick, reliable fastening with excellent grip.
- Precision Machined Threads: Ensures smooth thread engagement and consistent holding power.
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.
