Hex Nuts

Hex Nuts

Hex nuts are one of the most common types of nuts, known for their hexagonal shape which provides easy wrenching and turning. They are used in conjunction with bolts, screws, and other fasteners to secure materials together.

  • Standard six-sided nut design
  • Used in various applications for secure fastening
  • Compatible with a wide range of bolts and screws
  • Available in different materials like steel, stainless steel, brass, and nylon
  • Ideal for general-purpose use
