Brand: Satin
Satin M3-45 refers to a metric thread pitch (45 threads per millimeter) with a satin finish. The thread size is specifically M3 (3 mm diameter) and has a left-hand helix (M3 is a common size for screws and fasteners in electrical, electronic, and mechanical engineering applications). The satin finish, also known as a line finish, has a line-like appearance with alternate high and low ridges on the surface of the thread, providing a more aesthetically pleasing look over traditional thread finishes. It is commonly used in high-precision applications where appearance and surface finish are important.
