Carbon Steel Twist-off type tension control structural bolts with heavy hex head
Product Overview:
ASME/ANSI B18.2.6-2006 Twist-off type tension control structural bolt with heavy hex head is a fastener product with special design and high strength performance. The bolt thread diameter is from 1/2 inch to 1-1/2 inch. The bolts are made of high-strength alloy steel, and the torsional shear design allows for precise control of the bolt's pre-tightening force, ensuring that the connector can maintain a stable tightening state under load. For high-strength structural connections that require precise control of preload forces, such as Bridges, buildings, mechanical equipment, etc.
Grade:
4.8, 6.8, 8.8, 10.9, 12.9
Carbon Steel Twist-off type tension control structural bolts with heavy hex head Details
ASME/ANSI B18.2.6-2006 Twist-off type tension control structural bolt with heavy hex head is designed for high-performance structural connections and automatically achieves a predetermined tightening moment during installation through the principle of preloading, ensuring optimal performance at each connection point.
Functional characteristics
Application
Functional characteristics
- Automatic torque mechanism: the built-in torsional shear element automatically breaks when tightened to the set torque, ensuring that the ideal preload is reached every time the installation is done, avoiding over-tight or loose.
- Pre-set fastening force: Each bolt is equipped with a precise shear point before leaving the factory for consistent and controlled tightening without additional measuring tools.
- Anti-slip: The unique hexagonal head design increases friction and reduces the risk of loosening due to vibration.
Application
- Steel structure engineering: Bridges, stadiums, multi-storey parking lots and other steel structure system connection.
- Heavy equipment manufacturing: port machinery, mining equipment key assembly node.
- Power facilities: high voltage transmission tower, substation support system.
- Rail transit: subway cars, rail fixtures.
- Automotive manufacturing: The solid attachment of the body frame to the chassis.
