Carbon Steel Hexagon Bolt Grade 4.8 M8 1/4 Galvanized Heavy Load Industrial Applications

This carbon steel hexagon bolt features grade 4.8 steel, providing reliable strength for various industrial applications. The M8 size with a 1/4-inch thread ensures secure fastening in machinery, equipment, and construction projects. The galvanized coating offers excellent corrosion resistance, making it ideal for outdoor environments or places with moisture and chemicals.

Meeting ASTM A193 and A194 standards, this bolt can handle heavy loads and maintain high performance in demanding industrial settings. Commonly used in automotive, construction, and machinery industries where durability and strength are crucial.

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, especially beneficial in high-temperature and chemical environments. The M10 size with a 9/16-inch thread provides a strong, secure hold.

The polished finish offers enhanced corrosion protection while improving aesthetic appearance. Ideal for chemical industry applications, food processing plants, pharmaceutical equipment, and other facilities requiring high-quality, durable fastening solutions.

• Vibration Resistance: Strong structure and tight threading provide excellent vibration resistance, ensuring secure connections in environments with heavy vibration or shocks.
• Environmental Resistance: Stainless steel and galvanized hex bolts withstand harsh outdoor conditions, including marine environments and chemicals, with anti-corrosive and oxidation-resistant properties.
• Aesthetic & Functional: Stainless steel varieties offer a smooth, polished appearance suitable for architectural designs and decorative structures.

The value of grade 4.8 and 8.8 is divided by performance, with higher values indicating better performance. Key differences:

• 4.8 grade are standard bolts, while 8.8 grade are high-strength bolts.
• 8.8 grade bolts are made from low-carbon alloy steel or medium-carbon steel with heat treatment (quenching, tempering), unlike 4.8 grade.
• 4.8 grade bolts are made from unprocessed round steel, while 8.8 grade bolts undergo lathe processing for precise dimensions and smooth surfaces.
