Acme thread is a type of screw thread commonly used in mechanical applications. It features a trapezoidal shape, which provides a larger contact area between the threads, allowing for better load distribution and increased strength. This design makes it ideal for applications requiring linear motion, such as in lead screws and linear actuators. The standard angle of an Acme thread is 29 degrees, which helps reduce friction and wear during operation. Acme threads are often found in machinery, tools, and various industrial equipment, making them a popular choice for engineers and designers seeking reliable and efficient threaded connections.
