DIN601 defines the specifications for half round head square neck bolts, commonly known as carriage bolts. These bolts feature a distinctive half-round head and a square neck, which helps prevent rotation and provides a secure connection when tightened with a nut. They are widely used in various industries due to their strength and reliability.
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 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:
Prevention of Rotation: The square neck under the head prevents the bolt from rotating when a nut is tightened, ensuring a secure fit.Versatility: Suitable for a wide range of applications, including construction, automotive, and machinery.Easy Installation: The flat round head allows for easy installation with a socket or wrench.Corrosion Resistance: Often made from stainless steel (304/316), these bolts offer excellent resistance to corrosion, making them suitable for outdoor use.Load Distribution: The square neck helps distribute the load evenly, reducing the risk of damage to the connected parts.
Scope of
application
Construction: Used in building structures where a secure connection is required.Automotive Industry: Employed in the assembly of vehicles where a flush finish and secure fastening are needed.Machinery and Equipment: Used in machinery frames and equipment where a secure and adjustable connection is needed.Solar Mounting Systems: Utilized in solar panel mounting systems for securing panels to racks or structures.Furniture and Display Systems: Ideal for use in systems that require frequent assembly and disassembly.
