Product Characteristics
Application
Product Characteristics
- High strength: EN 781 steel structure hexagonal bolts are made of high-strength materials and are usually required to reach grade 8.8, 10.9 or higher strength grades to meet the high strength requirements of steel structure connections.
- High precision: the size and tolerance of the bolts are strictly controlled to ensure the interchangeability and reliability of the supporting nuts, washers and other parts.
- Good fastening performance: The large hexagonal head design enables the bolt to be evenly stressed during the fastening process, improving the stability and safety of the connection.
- Various surface treatments: Depending on the environment and needs, EN 781 bolts can be galvanized, blackened and other surface treatments to improve their corrosion resistance and appearance quality.
Application
- Construction field: Used for the connection of key parts such as frame structure, steel structure bridge, roof and wall structure to ensure the stability and safety of the building. In large construction projects, such as apartments, hotels, shopping malls and stadiums, the application of this bolt is particularly common.
- In the field of Bridges: EN 781 bolts play a vital role in various types of bridge structures, such as large sea Bridges, highway Bridges and urban road Bridges. They can withstand the huge weight and pressure on the bridge structure to ensure the safe operation of the bridge.
- Mechanical field: In mechanical equipment, such as cars, trains, ships, etc
