Hex Heavy Bolt Carbon Steel Grade 12.9 M16 7/16 Inch Black Oxide Finish High Strength Structural Support

Hex Heavy Bolt Carbon Steel Grade 12.9 M16 7/16 Inch Black Oxide Finish High Strength Structural Support

Product Description:

This high-strength hex heavy bolt is made from carbon steel grade 12.9, offering the tensile strength needed for structural support in critical applications. The M16 size with a 7/16-inch thread is ideal for large structural projects, such as steel structures, bridges, and high-load equipment. The black oxide finish provides an added layer of corrosion resistance and a sleek, professional appearance. This bolt is highly durable, making it perfect for industrial, mechanical, and structural applications that require heavy-duty performance and long-term reliability.

Hexagon Bolt Stainless Steel SS316L M10 9/16 Inch Polished Finish Corrosion-Resistant for Chemical Industry: The SS316L stainless steel hexagon bolt is designed for superior resistance to chemical corrosion. Its low carbon content ensures greater flexibility and prevents carbide precipitation, which is especially beneficial in high-temperature and chemical environments. The M10 size with a 9/16-inch thread provides a strong, secure hold in various industrial applications. The polished finish offers enhanced corrosion protection while improving aesthetic appearance. This bolt is ideal for use in the chemical industry, where resistance to corrosive substances, acids, and extreme temperatures is essential. It is also suitable for food processing plants, pharmaceutical equipment, and other facilities that require high-quality, durable fastening solutions.

Applications

12.9 grade screws usually refers to the use of SCM435 alloy steel material manufacturing, its minimum tensile strength of 1220Mpa, hardness of 39~44HRC ultra-high strength screws. Domestic mainly for the textile, hydraulic, injection moulding, machinery industry in use.
12.9 level is the top varieties of screws, with high hardness and tensile strength, its Rockwell hardness (HRC) up to 39-44 between the tensile strength of up to 1220N/mm2, but because of the shape of the screws manufactured differently, so the use of the same material production of countersunk head socket head cap screws (flat cups), half-round head socket head cap screws (round cups) can only be achieved at the minimum tensile strength of 10.9 level. The same can fully meet the high requirements of fasteners for special occasions and components of industrial and mining enterprises.
