When it comes to securing heavy-duty structures and machinery, the right fastener is crucial. That’s where Heavy Hexagon Bolts come into play. These specialized bolts are engineered for applications requiring high strength and reliability, making them a top choice in construction, infrastructure, and industrial settings. Heavy Hexagon Bolts feature a larger head and bearing surface compared to standard hex bolts, which distributes clamping force more effectively and reduces the risk of loosening under stress. Available in various grades and materials, these bolts are built to withstand extreme conditions, ensuring long-term performance and safety. Whether you're working on bridges, heavy equipment, or structural steel frameworks, Heavy Hexagon Bolts deliver the durability and holding power needed for critical connections.
Heavy Hexagonal Bolts are meticulously designed to meet rigorous industry standards, including ASTM and SAE specifications. Key characteristics that set these bolts apart include:
For detailed specifications, refer to the table below:
| Grade | Material | Size Range (Diameter) | Length Range | Tensile Strength (min) | Yield Strength (min) | Common Applications |
|---|---|---|---|---|---|---|
| ASTM A325 | Medium Carbon Steel | 1/2" to 1-1/2" | 1" to 30" | 120,000 psi | 92,000 psi | Structural Steel Connections |
| ASTM A490 | Alloy Steel | 1/2" to 1-1/2" | 1" to 30" | 150,000 psi | 130,000 psi | High-Strength Structural Applications |
| SAE J429 Grade 5 | Medium Carbon Steel | 1/4" to 1" | 1/2" to 8" | 120,000 psi | 92,000 psi | General Machinery & Equipment |
| ASTM A193 B7 | Alloy Steel | 1/4" to 4" | 1/2" to 36" | 125,000 psi | 105,000 psi | Pressure Vessels, Piping Systems |
Heavy Hexagonal Bolts are available in multiple finishes and coatings to enhance performance. Common options include plain (black oxide), hot-dip galvanized for corrosion protection in outdoor settings, and mechanical zinc plating for indoor applications. For high-temperature environments, Heavy Hexagonal Bolts made from heat-treated alloy steel retain their mechanical properties without compromising integrity. Custom lengths, threads, and head markings can be specified to align with project blueprints and safety regulations. Proper installation with calibrated torque wrenches is recommended to achieve the designed preload and joint security.
