This product description refers to a type of heavy hexagonal bolt made from stainless steel, conforming to either DIN933 (fully threaded) or DIN931 (partially threaded) standards. It includes a corresponding nut.

Key Specifications & Features:

• Standards: Conforms to DIN933 (fully threaded hex head bolts) and/or DIN931 (partially threaded hex head bolts), indicating the threading configuration.
• Material: Stainless steel, ensuring excellent corrosion resistance and durability in various environments.
• Material Grades:
  • A2-70: Austenitic stainless steel (A2 is equivalent to AISI 304), with a minimum tensile strength of 700 N/mm², providing good strength and general corrosion resistance.
  • A4-80: Austenitic stainless steel (A4 is equivalent to AISI 316), with a minimum tensile strength of 800 N/mm², offering superior corrosion resistance, especially in marine and chemical environments, along with higher strength.
• Sizes (Metric): Available in diameters ranging from M20 to M100. This indicates suitability for substantial, heavy-duty applications.
• Sizes (Imperial): Available in diameters ranging from 3/4 inch to 4 inches. This covers a wide range of large imperial sizes used in heavy construction and industrial sectors.
• Head Type: Heavy Hexagonal Bolt. As described previously, this features a larger, thicker hexagonal head designed for higher stress, greater torque capacity, and enhanced load distribution.
• Inclusion: Supplied with a corresponding nut, ensuring a complete fastening solution for the specified bolt.

Typical Applications:

Due to their heavy hex design, high-strength stainless steel materials (A2-70 / A4-80), and large size range, these bolts with nuts are ideal for:

• Heavy-duty construction, especially in structural steel connections where high loads and corrosion resistance are critical.
• Bridge construction and infrastructure projects.
• Marine and offshore applications (A4-80 highly recommended for salt water exposure).
• Chemical processing plants and corrosive industrial environments.
• Machinery and heavy equipment manufacturing, where robust and durable fastening is required.
• Power generation facilities and renewable energy installations.

These bolts offer excellent mechanical properties, strong resistance to rust and oxidation, and are designed for secure and long-lasting connections in demanding environments.
