Frequently Asked Questions about Threading

Which threads are miniature and which are micro?
A: In principle, there is no standardized definition of the terms "miniature" and "micro". Different industries have their own specific requirements for the size range of miniature and micro threads.
Generally speaking, miniature threads are usually defined as threads in the range of approximately 0.3 mm (.012 in) to approximately 2 mm (.08 in) in diameter. These threads are typically used in applications such as electronics, small appliances, and precision instruments.
In contrast, micro threads are typically smaller, with diameters generally under 0.3 millimeters (.012 inches). These extremely small threads are typically used in microelectronics, medical devices, optical equipment and other specific industries that require precision and miniaturization.
