Hex Flange Head is a commonly used connecting element, Hex Flange Head is used to connect two flanges together. The standards for hexagonal flange screws include the following aspects:
1. Size standards: The size standards of Hexagon Flange Bolts are usually formulated according to the International Organization for Standardization (ISO). Common dimensional standards include ISO 4014 and ISO 4017. These standards specify dimensional requirements such as Screw diameter, length, thread specifications, etc.
2. Material standard: The material of Hexagon Screw With Flange is usually carbon steel, alloy steel or stainless steel. Different application scenarios require different materials, so standards usually specify 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 Hexagonal Flange Bolt, hexagonal flange screws usually require surface treatment. Common surface treatment methods include galvanizing, 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 performance requirements for each strength grade.
To sum up, the standards for hexagonal flange screws cover aspects such as size, material, surface treatment and strength grade to ensure that the quality and performance of the screws meet the requirements. When using hexagonal flange screws, screws that meet the standard requirements should be selected according to the specific application scenario.
