ISO 7411-1984 Class 8.8 and Class 10.9 high strength steel structural bolts with hexagonal head bolt
Product details
Hexagon bolts for high-strength structural bolting with large width across flats-Property classes 8.8 and 10.9 is a kind of structural bolt featuring high strength, a wide across flats, and a hexagon head design.These bolts come in performance grades of 8.8 and 10.9, and their surfaces can undergo treatments such as blackening, hot-dip galvanizing, and dacromet, depending on specific requirements, to enhance corrosion resistance.
Functional Characteristics
- High strength: Bolts specified in ISO 7411-1984 have high strength characteristics and are usually used for structural connections that require large loads.
- Large width opposite side: The head of the bolt is designed to be large width opposite side, which is easy to tighten with tools such as wrenches.
- Hexagonal head design: The hexagonal head design increases the contact area between the bolt and the tool, and improves the stability and reliability of fastening.
ApplicationWidely used in steel structure engineering, such as bridges, construction, mechanical equipment and other fields. They are used to connect steel structural parts to ensure structural stability and safety.
- Construction: Used for the connection and fastening of steel structure buildings, such as bridges, high-rise buildings, etc.
- Mechanical equipment: plays an important role in the structural connection of heavy machinery, wind power equipment and other fields.
