  • Hexagonal flange bolts are widely used in industrial fields, civil construction fields, and heavy machinery such as cranes. During installation, it is necessary to ensure that the anti-slip wave pattern at the bottom of the flange disc fully contacts the connection surface, increasing the contact area and generating a locking effect to prevent loosening.

    Xunlong can provide flange bolts and flange nuts with or without serrations to match different usage scenarios, and customers can provide suggestions based on the actual usage scenarios.
