8.8 Nut Bolt Manufacturer

About Hexagonal Nut Bolts

Hexagonal Nut Bolts, or Hex Bolts, are characterized by their six-sided heads and threaded shafts, designed for secure fastening when used with compatible nuts. These bolts are widely used in mechanical, structural, and industrial assemblies due to their high reliability and robust performance. The 8.8 grade signifies superior tensile strength and resistance to wear and tear, making them ideal for heavy-duty applications.
