High Tensile Threaded Rod - Grade 8.8, 10.9, 12.9
A high-strength threaded rod is a high-performance toothed component widely used in various mechanical equipment as an element for transmitting motion and power. Due to its application demands under high-load and high-speed conditions, stringent requirements are placed on its strength, wear resistance, and service life.
The specifications of high-strength threaded rods are primarily determined according to the Chinese National Standard GB/T 15389-1994. Common specifications include:
Specifications
Diameter: M4, M5, M6, M8, M10, M12, M16, etc.
Length: Standard lengths of 1m, 2m, 3m, etc., with customization available based on requirements.
Grade: 8.8, 10.9, 12.9 (equivalent to Grade 8.8, 10.9, 12.9 under GB/T 15389-1994).
Key Applications:
- Construction Sector:
In large-scale structural projects such as bridges and high-rise buildings, high-strength threaded rods are used to connect steel components, ensuring structural stability and safety. They withstand immense tensile and compressive forces, guaranteeing the integrity of structures under various environmental conditions. - Mechanical Manufacturing:
The assembly of various types of mechanical equipment relies heavily on high-strength threaded rods. For instance, in heavy-duty machine tools and mining machinery, these rods ensure tight connections between components, preventing loosening under intense vibrations and heavy loads, thereby maintaining operational reliability. - Transportation Industry:
In the manufacturing of vehicles such as automobiles, trains, and aircraft, high-strength threaded rods are critical for securing key components like engines and chassis. These parts must endure impact forces and complex mechanical stresses during high-speed operation, and the high-strength properties of threaded rods ensure the reliability and safety of transportation systems. -
