Flange Bolts: Design, Advantages, and Industry Uses

This page focuses on flange bolts, characterized by an integrated flange (a wide, flat disc) beneath the head that eliminates the need for a separate washer. It explains the benefits of this design, including consistent clamping force distribution and vibration resistance—especially with serrated flanges that grip surfaces. Materials such as carbon steel, alloy steel, and stainless steel (304, 316) are discussed, along with their use in automotive, machinery, construction, and piping systems. The content compares serrated vs. non-serrated flange bolts, highlighting when each is preferred, and offers insights into installation and selection for various load and environmental conditions.

Frequently Asked Questions

How do serrated flange bolts differ from non-serrated ones?

Serrated flange bolts have small, sharp teeth on the underside of the flange, which dig into the surface of the connected material when tightened, creating a locking effect that resists loosening from vibration or movement. Non-serrated flange bolts have a smooth flange surface and rely on friction alone to maintain the connection, making them better suited for applications where surface damage must be avoided (e.g., on soft materials like plastic or painted surfaces). Serrated versions are preferred for high-vibration environments like engines or industrial machinery.

Sam Carter

Our factory's conveyor belts require frequent maintenance, and these flange bolts have significantly reduced downtime. The serrated flanges hold tight against metal surfaces, even during high-frequency vibrations, and the stainless steel construction resists corrosion from lubricants and cleaning agents. The bolts are easy to install with a impact wrench, and the uniform thread quality ensures quick nut engagement. While they're more expensive than regular bolts, the reliability and reduced maintenance make them cost-effective in the long run. A must for industrial machinery with vibration issues.
