Nuts are threaded components used in bolted connections. Their main function is to maintain the connection between two or more elements. The nuts are both a connecting element and a securing element for the connection. The advantage of this type of connection is that components can be repeatedly connected and disconnected without the risk of physical damage.

The most common nuts are hexagonal nuts with a through hole with an internal thread along the entire length of the hole, slightly less common are nuts with other characteristics depending on requirements.

Nuts come in a variety of sizes, materials and thread types to suit different applications and design requirements. The most common are nuts with metric threads and nuts with inch threads. The threads may be present along the full length of the nut, or they may be incomplete. Nuts can be right-handed (right-threaded nuts) or left-handed (left-threaded nuts), with a through hole or blind hole.

Nuts are used in a wide range of applications, whether in construction, automotive, industry or domestic applications. Critical to the durability and safety of the connection is the correct choice of nut in terms of its size and characteristics.

Special nuts belong to a group of non-standard nuts, designed and manufactured for specific applications or operating conditions. They are used in situations where the use of standard nuts is impossible or difficult due to their shape or characteristics.

Special nuts are distinguished by design or functional features that enable them to be used under specific conditions. They can be made from a variety of materials, such as steel, stainless steel, brass, copper, aluminium, bronze or plastics, and take different shapes according to their needs and purpose.

Use of special nuts:

Special nuts are mainly used in situations where:

  • it is not possible to apply standard solutions (‘regular’)
  • unusual nut shape required
  • unusual technical characteristics of the nut are required
  • the nut must have certain mechanical properties
As a manufacturer of caps, we offer the production of such nuts upon request:
  • nuts with metric threads
  • nuts with inch threads
  • nuts with trapezoidal threads
  • nuts with fine threads
