4.8 grade 8.8 grade 10.9 grade flat head hexagonal countersunk head hexagonal bolts
Countersunk hexagonal bolts, also known as flat cup hexagonal bolts, are commonly used in both imperial and metric systems, while commonly used materials include stainless steel and carbon steel. The outer edge of the screw head is circular, with a concave hexagon in the middle. Its head is a 90 degree cone, and after assembly, the screw head can be inserted into the assembly surface to keep it neat.
DIN7991 hex socket countersunk head screws are available in two materials: carbon steel and stainless steel. The performance grades of carbon steel hexagonal countersunk head screws are 8.8, 10.9, and 12.9, and the standard can refer to GB3098.1. Carbon steel materials generally require surface treatment, commonly including oxidation, electroplating, etc. If other surface coatings or surface treatments are required.
1. Furniture manufacturing: Hexagonal countersunk head screws are a beautiful and not easily loose substitute, widely used in the manufacturing of various types of furniture.
2. Architectural decoration: Hexagonal countersunk head screws can be used in architectural decoration, such as suspended ceilings, aluminum alloy doors and windows, etc.
3. Mechanical equipment: Hexagonal countersunk head screws can be used in vehicles, electrical equipment, ships, and other fields.
4. Other fields: The use of hexagonal countersunk head screws can also be extended to other fields that require high-strength connections and a flat and beautiful surface.
Internal hexagonal countersunk head screw is a special type of screw brought by the internal hexagonal structure, widely used in furniture, building decoration, mechanical equipment and other fields, with the characteristics of high strength, beautiful appearance, and not easy to loosen. Its use can also be extended to other fields that require high-strength connections and a smooth and beautiful surface.
