ANSI/ASME B18.2.2 is the American Society of Mechanical Engineers (ASME) standard for hexagon nuts. This standard covers general purpose hexagonal nuts, including machine nuts, hexagonal nuts, square nuts, hexagonal flange face nuts, and joint nuts.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

1. High strength: Hexagonal thick nuts are thicker than ordinary nuts, providing higher preload. 2. Reliability: Suitable for high-strength connections and occasions where disassembly is often required. 3. Compatibility: Conforms to ANSI/ASME B18.2.2 standard, ensuring compatibility with other standard parts.

Scope of Application

1.Construction industry: for the fixing of building structures. 2. machinery manufacturing: for the assembly of mechanical equipment. 3. automotive industry: for the fixing of automotive parts. 4. electronic equipment: for the assembly of electronic equipment.
