M6 M8 Carbon Steel Hex Heavy Duty Bolt with Nut Washer Galvanized Grade 8.8 Class 8.8
Product Description:
The M5 and M6 mild steel hex heavy head bolts with nut washers are a reliable fastening solution for light to medium-duty applications. Made from mild steel and galvanized for enhanced corrosion resistance, these bolts are commonly used in construction, automotive, and industrial machinery. The galvanization process provides a protective layer, making these bolts resistant to rust and environmental wear, while the grade 4.8 classification ensures sufficient strength for standard applications.
Features:
• Galvanized Coating: The galvanization process creates a zinc coating that enhances the bolt’s resistance to corrosion, making it ideal for use in outdoor or humid environments.
• Grade 4.8 Classification: The bolts are classified as Grade 4.8, meaning they have a tensile strength of 400 MPa and yield strength of 320 MPa, suitable for medium-strength applications.
• Heavy Head Design: The large hex head design improves torque application, ensuring secure and stable fastening.
Advantages:
• Cost-Effective: Mild steel bolts are generally less expensive than stainless steel bolts, making them a cost-effective choice for general-purpose applications.
• Corrosion Resistance: The galvanized coating significantly increases the bolt’s resistance to corrosion, extending its life compared to uncoated mild steel bolts.
• Ease of Installation: The hex head allows for easy tightening with standard wrenches, improving installation efficiency.
Maintenance Tips:
• Inspect regularly for signs of corrosion, especially at areas where the galvanization may be damaged.
• Clean bolts with a mild detergent to remove dirt and debris, which could affect the galvanization’s protective properties.
• In environments with extreme moisture, consider applying an additional protective coating to prolong the lifespan.
Applications
1,Vibration Resistance
- Due to their strong structure and tight threading, hex bolts offer excellent vibration resistance, making them suitable for environments with heavy vibration or shocks, ensuring a secure connection.
2,Resistant to Environmental Changes
- Stainless steel and galvanized hex bolts can withstand harsh outdoor environments, including exposure to marine conditions and chemicals. Their anti-corrosive and oxidation-resistant properties provide long-lasting performance.
3,Aesthetic and Functional
- Hex bolts, especially stainless steel varieties, offer a smooth, polished appearance, making them ideal for applications where aesthetics matter, such as in architectural designs and decorative structures.
Hex bolts are indispensable in various industrial and consumer applications due to their strength, versatility, and ease of use. They provide reliable and durable fastening solutions across multiple sectors.
Generally required chromium content of 18% or more, nickel content of 8% or more, because of its good corrosion resistance, heat resistance and other advantages, often used in food processing, storage and transport, or applied to agriculture, auto parts, building materials, chemical industry, etc., is the most widely used stainless steel, accounting for almost more than half of the total production of stainless steel. 316 stainless steel generally require chromium content of more than 16%, nickel content of more than 10%, molybdenum content of more than 2%, nickel and molybdenum, the two alloying elements of the proportion of the enhancement, so that it has a better resistance to (acid) corrosion, welding performance, and so on, and therefore have a higher price, in the medical and surgical, fine industrial components, etc. to play a greater use.
