Size: GB5787(10*70), GB5789(12*55)
Grade: 10.9, 8
Material: 10b21
Finish: Blue and white zinc plating, Heat treatment
Key Features:
- Hexagonal Head: The bolt has a six-sided hexagonal head, which allows for easy tightening with a wrench or socket.
- Flange: The flange is a circular, wide, and slightly raised washer that is integrated into the bolt’s head. It serves to improve load distribution and provide additional stability, often eliminating the need for a separate washer.
- Threading: Like standard bolts, hexagon flange bolts come with threads that match corresponding nuts or threaded holes for fastening.
- Material: Typically made of steel, stainless steel, or other durable materials. The flange may also have a coating (e.g., zinc-plated) to enhance corrosion resistance.
- Locking Mechanism: Some hexagon flange bolts feature a locking design, such as a nylon insert or serrated flange, to prevent loosening under vibration.
Common Uses:
- Automotive Industry: Used in automotive assemblies, including engine parts, chassis, and suspension components, where vibration resistance and load distribution are crucial.
- Heavy Machinery and Equipment: Used in industrial settings where secure and stable fastening is needed, particularly for larger equipment and structural assemblies.
- Construction: Applied in metal structures, where high strength and load-bearing capacity are essential.
- Electronics and Appliances: Common in equipment and appliances that require strong connections with low surface damage.
Advantages:
- No Washer Needed: The integrated flange eliminates the need for a separate washer, reducing assembly time and part count.
- Improved Load Distribution: The flange helps distribute the load more evenly, preventing damage to softer materials and enhancing the connection’s durability.
- Vibration Resistance: The design often provides better resistance to loosening under vibrations, especially in applications where constant movement occurs.
