Precision Connection: Fine Thread & Serrated Flange

The Hex Flange Bolt with Fine Thread and Serrated Flange combines the stability of a hex head screw with the integrated washer-like support of a flange head. The serrated flange increases grip, preventing loosening under vibration or dynamic load, while the fine thread ensures smooth, precise tightening with higher clamping force at lower torque.

Main Advantages

• Vibration-resistant connection due to the serrated flange underside.
• Fine thread bolt for accurate adjustment and secure fastening.
• Integrated hex flange head distributes pressure evenly.
• Available in steel and stainless steel, zinc-plated or coated for corrosion protection.
• Manufactured according to DIN/ISO standards.

Applications

Ideal for mechanical engineering, automotive manufacturing, metal fabrication, and industrial assembly, wherever long-lasting and vibration-safe fastening is required.

Materials & Finishes

• Steel (high strength), available zinc-plated, black oxide, or coated.
• Stainless steel for excellent corrosion resistance.

Quality Standards

Produced under strict DIN/ISO specifications ensuring dimensional accuracy and repeatable performance.

Available Sizes (M6–M12)

Frequently Asked Questions

What is the purpose of the serrated flange?

The serration prevents the bolt from loosening under vibration by increasing surface friction – ideal for dynamic applications.

Why use a fine thread?

Fine threads allow more precise torque control and higher clamping force, improving assembly safety and performance.
