A Guide to the Uses and Production Methods of Stainless Steel Double Headed Studs

Stainless steel double headed studs are specialized fasteners with threads on both ends and a smooth shank in the middle. This design makes them ideal for applications where two components need to be securely joined but cannot be connected directly with standard bolts. One end of the stud is screwed into a pre-threaded hole, while the other end is used to secure a nut. This fastening method is especially valuable in complex assemblies, offering both strength and reliability.

One of the most common applications of stainless steel double headed studs is in the automotive industry, particularly in the connection between the cylinder block and the cylinder head of engines. The cylinder block often features threaded holes where one end of the stud is fixed. The other end extends out and connects to the cylinder head with a nut. This approach not only simplifies disassembly for maintenance but also ensures a stable and leak-resistant connection under high-pressure and high-temperature conditions. Beyond automotive uses, these studs are widely employed in machinery, aerospace, new energy systems, and heavy equipment.

The production of stainless steel double headed studs involves precision engineering. A frequently used method for forming threads is the thread-rolling process. This involves placing the billet between two rolling plates that move in opposite directions, imprinting the thread profile onto the surface through cold forming. This technique is efficient and well-suited for mass production due to its speed and consistency. For larger diameter studs or applications requiring tighter tolerances, manufacturers may use turning or rolling processes to achieve the necessary thread accuracy and finish.
