trådprofiler
Trådprofiler refer to the shape of the threads on a screw, bolt, or nut. This profile is crucial for the proper functioning and strength of a threaded fastener. The most common type of thread profile is the V-thread, characterized by a triangular shape with flanks meeting at an angle. Within V-threads, there are several standards, such as the Unified National Coarse (UNC) and Unified National Fine (UNF) threads, which differ in their pitch (the distance between adjacent threads). The International Organization for Standardization (ISO) also defines metric thread profiles, commonly designated with an "M" followed by the nominal diameter and pitch.
Another important thread profile is the square thread, which has a rectangular cross-section. Square threads are
