Product Characteristics
Application
Product Characteristics
- Structural characteristics:The head of the bolt has a hole for easy penetration with steel wire or other materials to achieve series and mutual braking of multiple bolts, thus playing a role of anti-loosening. The hexagonal shape of the head makes it easy to tighten or disassemble with tools such as a wrench or screwdriver.
- Excellent performance: usually made of carbon steel material, hardness level of 8.8 (HRC22~34), with a certain strength and toughness. Surface treatment may include anti-corrosion measures such as blackening to improve the corrosion resistance and service life of the bolt.
- Hexagonal head: The head design is hexagonal, easy to use tools such as wrenches, screwdrivers to tighten or disassemble, improve work efficiency.
Application
- Construction: Used for the connection and fastening of steel structure buildings, such as Bridges, high-rise buildings, etc.
- Mechanical: Used in mechanical equipment to connect and fix key components to ensure the stable operation of the equipment.
- Transportation: Used in railway, road and other transportation facilities to connect and tighten tracks, Bridges and other structures.
