Double headed bolts have threads at both ends and a screw in the middle, commonly used to connect mechanical components such as mining machinery, bridges, automobiles, motorcycles, boiler steel structures, suspension towers, and large buildings.

When large equipment requires accessories like observation mirrors, mechanical seal seats, or reduction frames, double headed bolts are essential. One end screws into the body, while the other holds the accessory with a nut, allowing for frequent and convenient disassembly.

Ideal for cases where connector thickness is large or space is too restricted for standard hexagonal bolts, such as in concrete roof trusses, roof beam suspensions, and monorail beam systems.

Commonly used as mechanical fixed connecting rods with corresponding threads at both ends. The middle screw thickness can be varied based on specific industrial requirements.
