About the flange bolts, why it is common hex head? For bolts head with odd-numbered sides, the two sides of the wrench are not parallel. In the past, there were only fork-shaped wrenches, which made it inconvenient to twist the wrench. In addition, the twist angle is also an important factor to consider. If it is a four-corner, the wrench needs to be turned 90 degrees to fix the flange bolts, which is not conducive to installation in a narrow space; if it is an octagonal or ten-angle, although the twisting angle becomes smaller, the force is also small, and it is easy to be rounded. Therefore, the hexagonal shape is a more common choice for bolts.

According to different places of use, the types of hexagon flange bolts have different requirements. Generally speaking, hexagon flange bolts are widely used in industrial and civil construction, cranes, excavators and other heavy machinery.

With the changes in market demand, Aoke has developed a variety of new types of flange bolts. Cross recessed hexagon head flange bolts, hexagonal flange wood screws, hexalobular head flange bolts, flange 12-point screws and bihexagonal head bolts With flange.
