metric thread

A **metric thread** is a type of screw thread that follows the International System of Units (SI). It is widely used in manufacturing and engineering applications worldwide due to its standardized measurements in millimeters. Metric threads are defined by their major diameter and pitch, making them easy to identify and specify for fasteners, bolts, and nuts. Common examples include M6x1.0 or M10x1.5, where “M” denotes metric, followed by the diameter and pitch. This threading system ensures compatibility across different components and provides strong, reliable fastening in mechanical assemblies.
