A2-70 Stainless Steel Hex Bolt
A2-70 Stainless Steel Hex Bolts are manufactured from A2 stainless steel, which is commonly equivalent to 304 stainless steel, and are widely used for fastening applications requiring good corrosion resistance and reliable mechanical performance. The A2-70 designation indicates the material group and strength class, with a minimum tensile strength of 700 MPa, providing a suitable combination of strength and durability for general industrial applications.
Compared with standard carbon steel hex bolts, A2-70 stainless steel hex bolts offer better resistance to rust and oxidation, making them suitable for outdoor environments, machinery, equipment assembly and general construction applications. They are available in different sizes, thread specifications and finishes to meet various fastening requirements.
