A threaded lead screw is a mechanical component used to convert rotational motion into linear motion, or vice versa. It consists of a threaded shaft with a helical groove or thread running along its length, typically made of materials such as steel, stainless steel, or brass. Threaded lead screws find applications in various industries, including manufacturing, automation, robotics, and automotive. Here's an overview of threaded lead screws and their key features: Thread Profile: Threaded lead screws feature a helical groove or thread that spirals along the length of the shaft. The thread profile can vary depending on the application requirements, with common profiles including Acme threads, trapezoidal threads, square threads, and buttress threads. These profiles determine factors such as efficiency, load capacity, backlash, and self-locking characteristics..
