What are the screw header hexagon stretch-rod-series commonly used for?

The screw header hexagon stretch-rod-series is a key high-strength fastening and connection component, especially suitable for occasions with strict requirements on bolt tensile strength, preload accuracy and reliability. Its main application scenarios are concentrated in the industrial field that needs to withstand huge axial tension and achieve stable and lasting connection.

In the assembly of heavy equipment, engineering machinery and large structures, the screw head hexagon stretch-rod-series plays a cornerstone role. For example, in the tower connection of wind turbines, the flange sealing and fastening of large pressure vessels, and the body assembly of heavy truck engines, this type of component relies on its outstanding tensile performance and precise preload control ability to ensure that the connection point still maintains extremely high structural integrity and sealing under long-term dynamic loads, vibration environments and temperature changes, effectively preventing the risk of connection failure caused by stress relaxation. The design of the screw header hexagon stretch rod series enables it to evenly distribute the load-bearing stress, significantly reducing the stress concentration phenomenon.

In high-precision and safety-sensitive fields such as aerospace and rail transportation, the application of the screw header hexagon stretch-rod-series is also indispensable. Its excellent specific strength and fatigue resistance are crucial for reducing weight and ensuring safety under extreme working conditions at the key connection points between aircraft engine installation and high-speed train bogies. They meet stringent weight indicators and the highest safety redundancy standards. In addition, in many fastening connections involving heavy loads, precision or harsh environments such as large-scale mold manufacturing, shipbuilding, petrochemicals, and bridge steel structures, this series of products is one of the preferred solutions for achieving reliable, efficient, and long-term connections. It can be said that the screw head hexagonal tensile rod series is an indispensable "muscle and bone connector" for modern industrial equipment.
