Carriage bolts with flange nuts are a type of fastener designed for secure and stable connections. These bolts feature a round head with a square neck, which prevents rotation when tightened, while the flange nut provides a larger surface area for distribution of the clamping load. This combination is ideal for applications requiring strong, reliable fastenings.
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 of the carriage bolt prevents it from rotating when the nut is tightened, ensuring a secure fit.Load Distribution: The flange nut's wide bearing surface helps distribute the clamping load, reducing the risk of damage to the connected materials.Vibration Resistance: The combination of the carriage bolt and flange nut provides excellent resistance to loosening due to vibrations.Easy Installation: Carriage bolts are easy to insert into predrilled holes, and flange nuts can be quickly aligned and tightened.Aesthetic Appeal: The round head of the carriage bolt offers a clean, finished look, which is suitable for both functional and aesthetic applications.
Scope of
application
