DIN 912 hexagon socket head cap screws, also known as cup-head hexagon socket screws, feature a cylindrical head and a hexagon socket drive. They are widely used in mechanical installation due to their ease of fastening , and resistance to loosening. They are typically made from carbon steel and come in various surface finishes such as plain, black, zinc plated, yellow plated, H.D.G, and self-color. The common strength classes include 8.8, 10.9, and 12.9.
Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.
Grade: The product grade is divided into A grade and B grade, as well as different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.
Advantage：
Compact Design: The cylindrical head allows for a low profile, making it suitable for applications where space is limited.
High Torsional Strength: The internal hexagon drive provides a good grip and precise torque control, which is essential for precision assemblies.
Aesthetically Pleasing: The smooth cylindrical head offers a clean and finished look, ideal for applications where appearance matters.
Versatility: Available in a range of materials and finishes, these screws can be used in various environments and applications.
Reliability: They provide a secure connection and are less likely to loosen compared to externally driven screws.
Scope of
application
Automotive Industry: Used in the assembly of car parts where space and aesthetics are considerations.
Mechanical Engineering: Employed in machinery and equipment that require precise and secure fastening.
Electronics: Ideal for electronics housings and when a low profile is needed.
Construction: Used in construction machinery and agricultural vehicle equipment that require anti-corrosion and are often exposed to harsh environments.
General Assembly: Suitable for a wide range of applications in various industries where a strong and reliable fastening solution is needed.
