Gängfogar

Gängfogar, or threaded joints, are a common method of connecting two or more parts using screw threads. This type of connection relies on the interlocking helical ridges of a male threaded component, such as a bolt or screw, and a female threaded component, such as a nut or internally threaded hole. The threads are designed to create a strong mechanical bond when tightened.

The principle behind a gängfog is simple mechanics. As the male thread is rotated within the female thread, it moves axially, drawing the parts together. The force exerted by the threads converts rotational motion into linear motion, allowing for both assembly and disassembly. The friction between the thread surfaces is crucial for preventing the joint from loosening under vibration or load.

Gängfogar are widely used in countless applications, from simple furniture assembly to complex machinery and structural engineering. They offer several advantages, including ease of assembly and disassembly, adjustability, and the ability to create strong and reliable connections. However, they can be susceptible to loosening if not properly secured, and over-tightening can lead to thread damage. Various methods exist to enhance the security of gängfogar, such as using lock washers, thread-locking compounds, or cotter pins. The design and material of the threads are critical factors influencing the strength and durability of the joint.
