Description

Heavy Hex Nuts USS Grade 2 Steel Plain 3/8-16 is a versatile fastener designed for dependable, everyday fastening. Crafted from USS Grade 2 steel, this plain (uncoated) heavy hex nut delivers solid strength and reliable grip for a wide range of projects—from light to medium-duty assembly to machinery and structural work. The 3/8-16 thread size refers to coarse UNC threads, ensuring easy installation and compatibility with standard bolts.

  • Material: USS Grade 2 steel
  • Finish: Plain (uncoated)
  • Thread size: 3/8-16 UNC
  • Type: Heavy hex nut for maximum bearing surface
  • Applications: Construction, machinery, automotive, general hardware

Ideal for medium-duty fastening where a strong, reliable nut is needed. The heavy hex design provides more contact area with the mating bolt, improving torque retention and resistance to loosening under vibration. However, being plain steel, it offers basic corrosion resistance; for outdoor or moisture-prone environments consider plated or coated alternatives.

Stocked in sizes for easy procurement—add the 3/8-16 heavy hex nut to your cart today and ensure you have the right hardware on hand for your next project.
