Technical Parameters
Hexagon socket flange bolts are high-performance fasteners designed to combine the strength of hexagon socket head cap screws with the stability of an integrated flange. The flange provides a larger bearing surface, distributing load more evenly and reducing the need for separate washers. These bolts are widely used in machinery, automotive, and industrial applications where secure fastening, high torque capability, and reliable performance are essential.
