Hex flange bolts
The standards for flange screws include the following aspects:
1. Dimensional standards: The dimensional standards of hexagonal flange screws are usually formulated according to the International Organization for Standardization (ISO). Common dimensional standards include ISO 4014 and ISO 4017. These standards specify the dimensional requirements for screw diameter, length, thread specifications, etc.
2. Material standards: The material of hexagonal flange screws is usually carbon steel, alloy steel or stainless steel. Different application scenarios require different materials, so standards usually stipulate the material requirements for screws, including chemical composition, mechanical properties, etc.
3. Surface treatment standards: In order to improve the corrosion resistance and appearance quality of the screws, hexagonal flange screws usually require surface treatment. Common surface treatment methods include zinc plating, nickel plating, electroplating, etc. Standards usually specify surface treatment requirements, including coating thickness, adhesion, etc.
4. Strength grade standard: The strength grade of hexagonal flange screws is usually formulated according to the International Organization for Standardization (ISO). Common strength levels include 4.8, 8.8, 10.9, etc. These grades represent the strength and load-bearing capacity of the screw, and standards usually specify the mechanical property requirements for each strength grade.
In summary, the standards for hex flange screws cover aspects such as size, material, surface treatment and strength grade to ensure that the quality and performance of the screws meet requirements. When using hexagonal flange screws, screws that meet the standard requirements should be selected according to the specific application scenario.
