- 12-точечный фланцевый болт: While this term specifically denotes a flange-type bolt with a 12 point design, it can often be used interchangeably with the other two terms, especially when discussing their functions and design.
Common Materials
12 point stainless steel bolt:
Stainless steel 12-point bolts are commonly employed in automotive, marine, and industrial applications. Their high resistance to corrosion makes them suitable for use in environments exposed to moisture and chemicals, such as in engines and marine hardware. In the automotive sector, these bolts provide robust fastening solutions for engine components and chassis assemblies, ensuring durability and performance. Their ability to withstand high temperatures and pressures also makes them ideal for heavy machinery and construction equipment .
titanium 12 point bolt:
Titanium 12-point bolts are widely used in the aerospace industry due to their exceptional strength-to-weight ratio and resistance to corrosion. These properties make them ideal for critical applications in aircraft structures, engines, and components exposed to harsh environmental conditions.
carbon steel 12 point bolt
Carbon steel 12-point bolts are frequently used in construction and heavy machinery applications due to their high strength and cost-effectiveness. They are typically found in structural components, such as beams and columns, where they provide reliable fastening under significant loads. While carbon steel bolts may require surface treatments for corrosion resistance, they remain a popular choice for applications where strength and affordability are critical .
Common Surface Finishing
12 point bolt Plating & Electroplating:
Carbon steel, titanium alloy, and stainless steel materials can all undergo vacuum plating and electroplating surface treatments, yielding excellent results. However, these surface treatment processes tend to be relatively expensive.
If you need further details on the surface treatment processes or their benefits, feel free to ask!
electrophoresis:
Electrophoretic coating, like vacuum plating and electroplating, is applicable to carbon steel, titanium alloy, and stainless steel materials, producing excellent surface finishes. This coating method involves applying a charged paint to the surface of the metal, resulting in a uniform and durable layer that provides enhanced corrosion resistance and aesthetic appeal.
blackening:
Blackening is a surface treatment process commonly applied to metals, particularly carbon steel, to enhance corrosion resistance and improve aesthetic appearance. This process involves creating a black oxide layer through oxidation and deposition reactions, which provides additional protection to the metal surface.
12 point chrome bolt and coppering:
Common processing methods
cnc machining 12 point stainless bolt:
CNC (Computer Numerical Control) machining involves precisely cutting and shaping a bolt from a solid metal rod using computer-guided tools. This process allows for high accuracy and the ability to produce custom bolts with intricate designs. CNC machining is ideal for low-volume production and when tight tolerances are required. The finish quality tends to be very high, making it a preferred choice for specialized applications where quality and precision are critical, such as aerospace or high-performance automotive parts. However, CNC machining is generally more time-consuming and expensive compared to cold heading, particularly for high-volume production.
Cold Heading 12 Point Bolt:
Cold heading, also known as cold forming, is a process that shapes the bolt by forcing a metal blank into a die under high pressure. This method is much faster and more cost-effective for producing large quantities of bolts. Cold heading increases the material’s strength due to work hardening, making it a good choice for bolts requiring excellent mechanical properties. It is ideal for producing standard-sized bolts in large quantities. However, cold heading may lack the ability to achieve the same level of customization and precision as CNC machining, especially for complex geometries.
Precision and Customization: CNC machining provides higher precision and allows for custom designs, while cold heading is limited in its ability to produce complex geometries.
Production Volume and Cost: Cold heading is better suited for mass production due to its speed and cost-effectiveness, whereas CNC machining is more suitable for small batches and custom orders.
