Review NATIONAL HARDWARE Eye Bolt 300-lb. Load 1/2 Inch

The National N100-381 is a high-strength, 1/2 inch diameter bolt designed to support heavy loads. With a nominal tensile strength of 300,000 pounds, these bolts are ideal for industrial and construction applications where maximum load-bearing capacity is essential.

These bolts are manufactured to meet or exceed the stringent requirements of ANSI/ASME B18.2.1-2019 standards for bolting and studding. Each bolt undergoes rigorous testing to ensure it meets the specified tensile strength and other critical dimensions.

The N100-381 bolt features a hexagonal head design, providing a large contact area between the wrench and the bolt, allowing for easy application of torque. The head is also recessed, helping to prevent accidental contact with surrounding surfaces during tightening, reducing the risk of damage.

The bolt body is made of SAE 4340 steel, which is known for its excellent strength and toughness. The material undergoes a heat treatment process to further enhance its mechanical properties, ensuring the bolt can withstand the high loads it's designed for.

The N100-381 bolt comes with a protective zinc coating, which provides corrosion resistance, helping to maintain the bolt's structural integrity over time, even in harsh environments. The coating also makes it easier to handle and install the bolts without the need for additional lubrication.

In summary, the National N100-381 bolt is a heavy-duty, high-strength bolt designed for industrial and construction applications where maximum load capacity is required. It undergoes rigorous testing to meet or exceed ANSI/ASME standards and comes with a protective zinc coating for added corrosion resistance. The hexagonal head design ensures easy application of torque and reduces the risk of damage during installation.
