M6 M8 M10 Weld Nut Carbon Steel Grade 8.8 12.9 Weld Hexagon Nut Hot-Dip

Product Specification

M6 M8 M10 Weld Nut Carbon Steel Grade 8.8 12.9 Weld Hexagon Nut Hot-Dip Galvanized
 
Product Description:

This weld nut is constructed from high-strength carbon steel in grades 8.8 and 12.9, making it perfect for medium to heavy-duty applications that require high tensile strength and durability. Available in sizes M6, M8, and M10, this weld nut is ideal for use in construction, automotive manufacturing, and machinery where secure, long-lasting threaded connections are critical.

Grade 8.8 carbon steel offers a moderate strength level suitable for most general applications, while grade 12.9 is a high-strength steel ideal for more demanding environments. These two grades ensure that the weld nut will maintain its integrity under both light and heavy loads. The 8.8 grade is typically used in standard machinery, while the 12.9 grade is well-suited for heavy-duty industrial applications requiring additional strength.

The hot-dip galvanizing process gives this weld nut a thick, protective coating of zinc, which significantly enhances its resistance to corrosion. The galvanizing process involves immersing the weld nut in molten zinc, providing a strong and durable protective layer that prevents rust and degradation even in the harshest outdoor conditions. This makes it a perfect choice for applications in construction, heavy machinery, and other environments where exposure to moisture, chemicals, or saltwater is common.

The hot-dip galvanized finish also improves the durability of the weld nut and ensures that it retains its integrity even under repeated exposure to stress or harsh environments. The galvanized coating offers both aesthetic benefits, with a shiny, metallic finish, and practical benefits, including improved resistance to wear and tear.

This weld nut provides a secure, stable, and corrosion-resistant solution for threaded fastening needs in various industrial and commercial sectors.

Applications

Compared with carbon steel, stainless steel fasteners have the characteristics of high temperature resistance and corrosion resistance, stainless steel is also more widely used in our life, what are the advantages of stainless steel in the end?

The first point, high temperature resistance

Stainless steel fasteners high temperature resistance: it is because the hardness of the stainless steel fasteners itself is strong enough, after the production and processing of fasteners have a strong anti-oxidation ability, and it is also able to work properly at high temperatures, so it will not be subjected to high temperatures too much interference. If the stainless steel fasteners can be used after manufacturing at the same time before passivation, then its effect will become better.

The second point, the rate of electric Yin

Stainless steel fasteners electro-negative rate: the physical properties of stainless steel fasteners have a high electro-negative rate, so and carbon steel wire compared to stainless steel fasteners than its electro-negative rate is five times higher. After testing, we concluded that there is a coefficient of expansion in the fastener, if the temperature is higher, then the expansion coefficient of stainless steel fasteners will gradually increase with the temperature.

The third point, force capacity

Stainless steel fasteners stress capacity: for stainless steel fasteners, its stress capacity to carry the load is medium, even if it can not be comparable with high strength bolts, but the stress capacity of stainless steel fasteners can also meet the daily needs of people.

The fourth point, mechanical properties

Mechanical properties of stainless steel fasteners: in the mechanical properties, most of us have learnt that many of the mechanical properties of fasteners have a great relationship with the stainless steel wire. For example: will not rust, high corrosion resistance, etc., these are with the nature of the stainless steel material itself has a great relationship, with the continuous development of fasteners, these mechanical properties have become stronger.

High corrosion resistance: 316 stainless steel contains molybdenum, which can show better corrosion resistance in chloride environment, so it is widely used in marine, chemical, pharmaceutical and other fields. Good high temperature resistance: 316 stainless steel high temperature strength and oxidation resistance are better than 304 stainless steel, can maintain stable performance in high temperature environment. Good mechanical properties: 316 stainless steel has high strength, plasticity and toughness, suitable for manufacturing high-strength mechanical structures. Suitable for welding: 316 stainless steel has good welding performance and can be processed by various welding methods. Disadvantages: higher price: due to the presence of molybdenum and other precious metal elements, 316 stainless steel price is relatively high. Processing difficulty: 316 stainless steel hardness is relatively high, processing is more difficult, need to use higher cutting force and cutting speed. Higher environmental requirements: 316 stainless steel in the manufacturing process requires the use of higher purity gas and water, requiring a clean and dust-free production environment.
