304 - Stainless Steel - Serrated - Hexagon flange bolt
Our Grade 304 (A2) serrated hexagon flange bolts act as the industry standard for reliable, vibration-proof fastening in outdoor and industrial environments. Combining the excellent corrosion resistance of 18/8 stainless steel with a built-in locking mechanism, these bolts eliminate the need for separate washers. The serrated flange face bites into the mating surface, ensuring the assembly remains tight even under dynamic loads, making them a favorite for solar racking and automotive components.
- A2-70 Grade: Manufactured from 304 stainless steel with a minimum tensile strength of 700 MPa, balancing strength with ductility.
- Self-Locking: The under-head serrations create a ratchet-effect that resists loosening caused by vibration or thermal expansion.
- Cost-Effective: SS304 offers the best price-to-performance ratio for corrosion resistance in standard atmospheric conditions.
