Commodity | Stainless Steel Heavy Hex Bolts |
Material | Made from 304 stainless steel, these screws have good chemical resistance and may be mildly magnetic. They are also known as A2 stainless steel |
Head Type | Hex Head |
Length | Is measured from under the head |
Thread Type | Coarse Thread, Fine Thread.Coarse threads are the industry standard; choose these screws if you don't know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance |
Standard | Screws that meet ASME B18.2.1 or formerly DIN specifications comply with these dimensional standards. |
Advantage
High Load Capacity | The heavy hex design distributes load more evenly, reducing the risk of loosening under stress. |
Enhanced Torque Application | Thicker hex head allows for higher torque during installation, ensuring a secure fit. |
Corrosion Resistance | Performs reliably in harsh environments, including exposure to chemicals and moisture. |
Durability | Built to withstand extreme conditions, reducing the need for frequent replacements. |
Wide Compatibility | Meets industry standards for heavy-duty applications. |
Application
Construction | Used in structural steel connections, bridges, and high-rise buildings. |
Oil and Gas Industry | Essential for pipelines, drilling equipment, and refineries. |
Heavy Machinery | Perfect for mining equipment, cranes, and agricultural machinery. |
Power Generation | Used in power plants and wind turbines. |
Transportation Infrastructure | Ideal for railways, highways, and airport construction. |
