Hex Flange Bolt Description

Flange bolts have a circular flange under the head that acts like a washer to distribute the load. Flange bolts that are non-serrated are sometimes called frame bolts.

The flange bolts are usually used in vehicle frames, especially in trucks and anywhere a head bolt is required. They feature a nozzle, thereby speeding the assembly while eliminating the washer. They render four times the bearing area than of a standard hex screw.

Frame bolts, also known as hex flange screws, are a one-piece hex-washer head bolt with a flat bearing surface. Frame bolts are commonly used on truck frames, giving them their name.

The head of the hexagonal flange bolt is composed of two parts: the hexagonal head and the flange surface. The "ratio of the supporting area to the stress area" is larger than that of the ordinary hexagonal head bolt, so this bolt can withstand higher pre-tightening force and prevent The loose performance is also good, so it is widely used in automobile engines, heavy machinery and other products.

Hexagonal flange bolts are particularly commonly used in the industry as industrial equipment and appliances. They are widely used because of their accurate decoration and strong endurance. They are widely used on highways and railway bridges, including industrial and civilian use. Construction, cranes, excavators and other heavy machinery.
