The hex nut, also known as a hexagon nut, is one of the most fundamental and universally used fasteners. It is characterized by its six-sided (hexagonal) shape and a centrally threaded hole.

Its primary function is to mate with a bolt, screw, or stud to secure components together. The key features and advantages of its design are:


  • Practical Geometry: The hexagonal shape provides multiple flat surfaces, allowing for easy gripping and turning with common hand tools (like wrenches or sockets) from various angles.

  • Effective Torque Application: The design allows for the effective application of tightening torque, creating a strong, reliable, and often demountable joint.

  • Wide Availability: Hex nuts are manufactured in a vast range of materials (carbon steel, stainless steel, brass, nylon), strength grades (e.g., Grade 4, 8, stainless steel markings), sizes (from miniature to very large), and thread types (metric or imperial).


Common variants include thick nuts, thin (jam) nuts for locking, nyloc nuts with an integrated nylon ring for vibration resistance, and flange nuts with a built-in washer face.

These nuts are indispensable across virtually all industries, including construction, machinery, automotive, aerospace, and general manufacturing and repair. They are standardized under specifications such as ISO 4032 (metric hex nuts) and ASME/ANSI B18.2.2 (imperial hex nuts).
