Hexagon Head Combination Bolts

Hexagon head combination bolts are integrated fasteners that combine a hexagon head bolt with one or more other functional parts (e.g. spring washers, flat washers, etc.) to form a pre-assembled unit. The thread design of the screw part is precise and fits tightly with the nut or internal thread to ensure a strong and reliable connection.

The unique feature of hexagonal head combination bolts is that combination elements such as flat washers and spring washers are also integrated into the bolt. Flat washers increase the contact area between the head of the bolt and the part to be connected, spreading the pressure evenly and preventing the surface of the part from being crushed. Spring washers provide constant elastic pressure, preventing the bolt from loosening under vibration or dynamic loads, which greatly improves the stability and durability of the connection.

Hexagon head combination bolts have a wide range of applications. In the machinery industry, it is often used in automobile parts, aviation and spacecraft, power industry and heavy machinery. In the construction field, it is often used for the connection and fixing of building structures and bridges. In the automotive industry, it is an important part of the automobile engine, brake and suspension system.
