Fasteners, fastening techniques
Fasteners are components used to connect and secure different parts and assemblies within structures or equipment. These elements are used in a wide variety of fields, from construction and engineering to engineering to the automotive, electronics and furniture industries.
The main types of fasteners:
- Screws are threaded elements that fasten two or more parts by screwing them together. They are often used with nuts to create a secure connection.
- Nuts are internally threaded components used in conjunction with screws or threaded rods for secure fastening.
- Washers are flat discs placed between the head of a bolt or nut and the surface of the workpiece. They distribute the clamping force evenly over the surface and protect the parts from damage.
- Rivets are used to make permanent joints between two or more parts. They are inserted into a pre-drilled hole and then deformed (by hammering or pressing) to fix the parts.
- Threaded shafts are rods of metal or other material with threads running the full length of the shafts, designed for the attachment or connection of components requiring greater tightening and strength or connecting parts.
- Dowels are fasteners used primarily in the construction industry for fixing elements in masonry or concrete. They are inserted into pre-drilled holes and extended by the insertion of a screw for a tight fit.
- The pins are used for temporary or permanent alignment and assembly of two parts.
Quality fasteners increase the life of the assembly and make it resistant to extreme conditions (e.g. vibration, humidity, high temperatures).
Secure joints reduce the risk of failures, accidents and injuries in critical applications such as construction and industrial equipment.
The right choice of these components, depending on the application, is essential for the reliability, safety and efficiency of the final assembly.
