The stainless steel hex socket bolt, also commonly known as the stainless steel cylindrical head hexagon socket screw or stainless steel cup head screw, is a widely used fastener. Its defining feature lies in the hexagonal socket designed in the head, which requires a special hexagon wrench for tightening or loosening operations. This design ensures higher torque transmission efficiency and better stability during the tightening process.
The stainless steel hex socket bolt is primarily made of austenitic stainless steel, such as grades 304 and 316. These materials excel in rust and corrosion resistance, enabling them to meet the demands of long-term usage. As a result, the stainless steel hex socket bolt finds widespread applications in various environments and industries, including chemicals, food processing, pharmaceuticals, electronics, and aerospace.
