Types of USA Nuts

These nuts are typically supplied in Grade 5 steel and are used in general construction, equipment repair, and light manufacturing. They are available in multiple finishes to provide corrosion resistance and support specific industry requirements.

USA Structural and Heavy Hex Nuts

USA heavy hex nuts are larger and stronger than finished hex nuts, designed for structural applications. They are paired with structural bolts such as A325 and A490 and are commonly specified in bridges, buildings, towers, and infrastructure projects. Manufactured to meet ASTM standards, heavy hex nuts are relied on in projects where safety and long-term performance are critical.
