Review NATIONAL MFG/SPECTRUM BRANDS HHI Eye Bolts Stainless Steel 5/16 Inch

The National Mfg. / Spectrum HHI N221-622 bolts are a high-quality fastener solution for various applications. These steel bolts are manufactured in the USA by National Mfg. Co., a reputable name in the industry known for their commitment to engineering excellence and innovation. The specific model in question, the HHI N221-622, is designed to meet the demands of heavy-duty use.

These bolts are made of carbon steel and feature a 5/16 inch nominal size. The thread pitch is UNC, which stands for Unified National Coarse. This thread design is widely used in North America for various bolt and screw applications due to its versatility and compatibility with various materials.

The HHI N221-622 bolts are designed to deliver superior strength and durability. They have a minimum tensile strength of 120,000 psi (pounds per square inch), ensuring they can withstand significant loads. This makes them well-suited for applications in construction, manufacturing, and other industries where high load-bearing capabilities are essential.

The heads of these bolts are hexagonal in shape, allowing for easy application with standard hex wrenches. The hexagonal shape provides a larger contact area between the wrench and the bolt head, ensuring more torque can be applied and reducing the risk of rounding or damaging the head during installation. The bolts also come with a lock washer and a nut to ensure a secure connection.

These bolts have a zinc coating, which provides corrosion resistance and extends their lifespan in harsh environments. The zinc coating is applied using a hot-dip process, ensuring even coverage and maximum protection against rust and other forms of corrosion.

In summary, the National Mfg. / Spectrum HHI N221-622 bolts are a high-performance, heavy-duty fastener solution. They are manufactured in the USA, made of carbon steel, and feature a 5/16 inch nominal size and UNC thread pitch. These bolts have a minimum tensile strength of 120,000 psi and come with a hexagonal head, a lock washer, and a nut for easy installation. They have a zinc coating for corrosion resistance, making them a reliable choice for various industrial and construction applications.
